Healthy Weight Loss With Alpha Lipoic Acid

Alpha lipoic acid (ALA) is a well known dietary antioxidant that has been shown to have multiple antioxidant functions including the scavenging of reactive oxygen and nitrogen species, the regeneration of other antioxidants and the enhancement of at least one of our own cellular antioxidants.  Alpha lipoic acid is found in several foods including organ meats like liver and kidney and plants like broccoli and spinach.  However, absorption of ALA from food is reported to be very low; therefore, individuals taking ALA for its antioxidant benefits generally take a dietary supplement.  While it has been suggested that ALA might have a number of health benefits related to its antioxidant function, little is known about its utility in weight management practices.

A new obesity research study explored the possible weight loss benefits of alpha lipoic acid.  For this obesity research study, investigators treated nearly 600 obese and nearly 500 pre-obese men and women with 800 mg alpha lipoic acid per day for a total of 4 months.  On average, pre-obese men and women lost about 8% of their body weight, reduced their body mass index (BMI) by 2 points, and reduced their waist size by about 2.5 to 3 inches.  Similarly, consuming alpha lipoic acid daily for 4 months resulted in a 9% decrease in body weight, a 3-4 point decrease in BMI, and a reduction in waist size of 3.5 to 4" in obese men and women.

This is an interesting study that will need some additional follow-up and confirmation.  While these obesity research results were very positive, this study did not appear to have a control group of individuals that did not take the alpha lipoic acid supplement.  Furthermore, the study summary does not indicate if the study participants were following any diet and/or exercise regimens in addition to taking alpha lipoic acid daily for 4 months.  Previous research in rodents suggests that alpha lipoic acid successfully induced weight loss by reducing food intake and enhancing energy expenditure.  Alpha lipoic acid is a very popular antioxidant that some consider to be a "universal" antioxidant because of its unique characteristic of being both fat- and water-soluble.  Despite its antioxidant benefits, more research is needed to confirm its role in any healthy weight loss program.  If you choose to use diet pills, whether it is alpha lipoic acid or one of the other popular diet pills, it is important to remember that these are best used as part of an overall weight loss strategy that includes appropriate caloric intake and adequate amounts of exercise.

Take Small Bites & Chew Slowly!

Retronasal aroma release is the process by which food aromas are released and sensed through our mouths during chewing.  Research has suggested that increasing the level of aromas released in this way can increase our feelings of fullness and potentially reduce our food consumption during a meal.  While we apparently each have individual differences in how well we recognize these food aromas, studies are being conducted to find ways to enhance the release of these aromas.  This includes research into different food processing methods and the effects of different eating patterns.

A new research study published online ahead of print in the British Journal of Nutrition examined the impact of bite size and chewing duration on retronasal aroma release.  In the initial part of the study, investigators asked 21 young, healthy, normal-weight volunteers to either eat freely or to eat two different fixed bite sizes.  In the second part of the study, the same volunteers were asked to either chew the food quickly (3 seconds) or more slowly (9 seconds).  During each part of the study, aroma release from the food was measured in the study volunteers.  The results of this investigation showed that:

• Taking multiple small bites of food resulted in a substantially greater release of food aromas compared to a smaller number of large bites.
• Chewing the test food for a longer duration resulted in a higher level of aroma release compared to chewing for a short length of time.
• Combining small bite size with longer chewing time did not enhance aroma release compared to either small bite size or longer chewing time by themselves.

This is a fascinating research study, which suggests that consuming our food in small bites and/or chewing more slowly releases greater amounts of aroma from the food we eat.  If retronasal aroma release is linked to an increase in feelings of fullness as some studies suggest, then eating smaller bites or chewing more slowly might cause us to feel full more quickly at meal time.  This has the possible long term effect of causing us to eat less food, assuming we listen to our bodies and actually stop eating when we feel full.  Additionally, this has the possibility of providing us with a more enjoyable dining experience based on the higher levels of food aromas we sense while eating.  Many of us have already developed particular eating habits with some eating very quickly and others eating more slowly.  Learning new, slower eating habits can be difficult for some of us, so choosing foods that lend themselves to taking smaller bites or choosing foods that are naturally chewy might be a good way to start developing better dining habits.

Higher Calcium & Vitamin D Levels Support Weight Loss

The effect of vitamins and minerals on weight loss has been and remains an active area of research investigation.  Two of the most studied are calcium and vitamin D; however, the results to date have been mixed and inconsistent making the role of the calcium and vitamin D in weight loss somewhat controversial.

A new weight loss study published online ahead of print in the American Journal of Clinical Nutrition further examined this possible relationship.  Weight loss researchers collected and analyzed data from 322 volunteers who took part in the 2-year Dietary Intervention Randomized Controlled Trial.  The results of the weight loss researchers analysis showed that:

• Vitamin D blood levels at the beginning of the study were lower in volunteers with higher body mass index (BMI) scores.
• At 6 months, higher levels of dairy calcium consumption were linked with greater weight loss.  An average of 580 milligrams of calcium per day was linked to a weight loss of about 12 lbs on average, while intake of about 360 milligrams per day on average was associated with a weight loss of about 8 lbs.
• Similar results were observed for vitamin D.  Blood levels of about 30 ng/ml vitamin D on average were also associated with a weight loss of about 12 lbs.
• Each incremental increase in dietary calcium intake was associated with about a 45% increased chance of losing 10 lbs, while each incremental increase in vitamin D blood levels increased the chances of successfully losing 10 lbs by about 70%.

These are excellent results indicating that higher consumption of calcium and higher blood levels of vitamin D, two important micronutrients, might be related to greater weight loss while dieting.  In general, it is very important to make sure you get adequate amounts of vitamins and minerals when dieting since dieting has been reported to lead to insufficient micronutrient intake.  This study not only supports that, but also indicates that getting enough of these two micronutrients might be one key to successful weight loss.  If you are not getting adequate amounts of these and other micronutrients through your regular diet and lifestyle, a good multivitamin/multimineral can be a good way to get your fully daily complement of vitamins and minerals.

Exercise Reduces Genetic Likelihood Of Obesity

While it is clear that being overweight or obese can be the result of too many calories consumed and not enough exercise, it is just as clear that genetic factors can play a major role in a person's risk for becoming obese.  In fact, research has shown that at least 12 different gene locations are involved in increased body mass index (BMI) and that these 12 different gene locations can be used to determine a person's chances of becoming obese by calculating a genetic predisposition score.  What is less clear is whether exercise can overcome a person's genetic likelihood of becoming obese.

Investigators collected data from over 20,000 men and women who took part in the European Prospective Investigation of Cancer - Norfolk (EPIC-Norfolk) study in an attempt to examine the possible relationship between physical activity and the genetic risk for obesity (free to download).  Physical activity was determined with a questionnaire and categorized as inactive, moderately inactive, moderately active, and active.  A genetic predisposition score was calculated for each study subject by adding up the changes at the 12 different gene locations linked to increasing BMI.  Analysis of the interaction between genetics and physical activity showed that:

• When all study subjects were examined together, each additional BMI-increasing gene was linked to a 0.154 increase in BMI.
• This was even greater in the inactive volunteers where each BMI-increasing gene was linked to a 0.205 increase in BMI.
• In contrast, each additional BMI-increasing gene was only linked to a 0.126 increase in BMI in active individuals, indicating that exercise suppressed the genetic effects on body mass.
• Moderately active and moderately inactive individuals showed an intermediate effect on BMI-increasing genes, suggesting that even small amounts of activity can help fight against the genetic likelihood of becoming obese.
• When looking at obesity risk instead of body mass index, taking part in regular physical activity suppressed the genetic predisposition for obesity by about 40%.

These are both fascinating and important results.  Overall, this study shows us that while genetics certainly play a role in obesity risk and weight gain, exercise can dampen the effects of genetics.  Interestingly, the study investigators report that even exercising less than 30 minutes per day can have a positive effect on one's genetic likelihood of becoming overweight or obese.  While getting enough exercise is an important part of a healthy lifestyle for everyone, individuals who are genetically predisposed towards becoming overweight might gain additional benefit from a regular exercise routine.  So rather than believing that one's genetics doom us to being overweight, it is important to remember that exercise can fight back against one's genetic risk for obesity.

In addition to making exercise an important part of our fight against obesity, following a healthy eating plan can also be critical.  My easy diet plan is a great way develop better eating habits and lose weight while still enjoying delicious tasting foods.  Visit us at www.drtabor.com to learn more or tune in to watch me on QVC September 12th from 1 AM - 2 AM EST!

Don't Make Food Your Reward!

We all experience differences in weight loss success with some of us able to lose weight much easier than others.  In many cases, this can be simply due to differences in the amount of exercise we do; however, some research shows that these differences exist even when the exercise routine is supervised.  The reasons for this are not completely clear, but a new exercise and weight loss study suggests that differences in how we desire food after exercise might play a part in the individual differences in weight loss.

In this new weight loss study, which is free to download, obesity researchers examined exercise-induced changes in the perceived reward value of foods in overweight and obese volunteers.  Study volunteers followed a supervised exercise routine designed to burn 500 Calories per day, 5 days per week for 12 weeks.  The reward value of food was measured in each study volunteer using a computerized procedure that measured liking, wanting, and food preferences based on photographic food images that showed foods with different tastes and fat contents. Study volunteers were classified as Responders (exceeded predicted loss in fat mass) and Non-Responders (lower than expected loss in fat mass) and differences in their perceived reward value of food after exercise were examined at the start and end of the study.  The obesity researchers reported that:

• Responders lost an average of about 11 lbs in 12 weeks compared to Non-Responders who lost an average of 4 lbs.
• After a bout of exercise, the liking for all foods remained unchanged in Responders.  In contrast, Non-Responders experienced an increase in their liking for all foods immediately after an exercise session.  This perception in reward value of foods was similar at both the start and end of the study in both groups of volunteers.
• After an exercise session, Non-Responders showed a greater desire for high fat foods than Responders.
• Non-Responders experienced an increased preference for high fat, sweet foods immediately after exercise, while Responders showed an increased preference for low fat, non-sweet foods after exercise.

This is a fascinating study that concludes that overweight and obese individuals who show an increased desire for food, especially foods high in fat and sugar, immediately after an exercise session lost less weight.  One of the interesting aspects of this study is the fact that even individuals who successfully lost weight showed an increased desire for food; however, their preferences were for non-sweet, lower fat foods.  The obesity researchers also indicated that the preference for high fat, sweet foods after exercise in Non-Responders was only seen at the beginning of the study, suggesting that exercise if maintained regularly might be able to eventually overcome these preferences.  It is apparently unclear why some individuals experience a heightened desire for foods after exercise while others don't.  The study authors suggested that differences in brain hormones after exercise might sensitize some individuals to food and food cues.

This study shows the importance of not making food a reward for weight loss or exercise.  Of course, it makes sense to not use food as a reward because we often eat more than planned and defeat the purpose of exercise.  However, knowing that exercise might increase our desire for food makes it even more important to set up other reward systems.  For example if you meet an exercise goal, plan a relaxing day at the pool, beach or at the spa. Just make sure it is not food!

What reward system do you use?

Exercise in an important part of any good diet or weight loss plan.  My easy diet plan, which uses delicious high protein, low-glycemic bars and shakes, recommends walking 30-45 minutes a day as a great way to start exercising.  Tune in to watch me on QVC September 12th from 1 AM - 2 AM EST!

Lose Belly Fat - Support Normal Blood Vessel Health

Just a few days ago, I mentioned the fact that excess belly fat is dangerous to our health.  These research studies have reported that excess belly fat (also called abdominal obesity) has been linked to poor heart health, poor blood sugar health, and overall mortality.  Previous studies have implied that belly fat gain might be linked to poor heart health by inducing changes in blood vessel health and the ability of blood vessels to stretch normally.  However, this potential link between belly fat and blood vessel health was unclear.

In an attempt to start better understanding the potential interaction between belly fat and normal blood vessel health, heart health researchers examined changes in blood vessel health during a short-term belly fat study (free to download).  For this study, the investigators recruited 43 healthy volunteers with a normal body weight and assigned them to either (1) maintain their weight for 16 weeks or to (2) gain weight for 8 weeks and then lose weight during a second 8-week period.  Changes in the ability of arm blood vessels to stretch and relax were measured at the beginning of the study, after weight gain and at the end of the study.  The heart health researchers reported that:

• Volunteers assigned to gain weight gained about 9 lbs on average over 8 weeks with over 80% of the weight gained as fat.
• In study volunteers that were asked to maintain their body weight, blood vessel health remained normal and unchanged.
• Volunteers who gained weight and belly fat developed poorer blood vessel health with substantial loss of blood vessel stretchability.
• Weight loss after the short-term weight gain resulted in a return to normal blood vessel health.

This is a fascinating study indicating the importance of maintaining a normal body weight or losing excess belly fat  for the support of normal blood vessel health.  According to these current study results, even a modest belly fat gain like seen during vacations or around the holidays can negatively impact blood vessel health.  Fortunately, losing this excess belly fat helped support normal blood vessel health.  While this study shows the possible impact of belly fat on normal blood vessel health, it also raises some interesting questions that will likely be the focus of future research studies.  For example, what happens to normal blood vessel health during long-term (over several years) weight gain, which is typical in many of us?  Also, can losing weight after years of carrying around excess belly fat still help with the support of normal blood vessel health and if so, to what extent?  And, how does weight cycling effect normal blood vessel health.  I look forward to seeing the answers to these types of questions in the future.

Watch What You Eat - Choose Healthy Carbs

Obesity has become a serious problem in the U.S. with approximately two-thirds of our population considered overweight or obese.  In fact, it has been reported that obesity rates have increased in 28 states and 8 states have obesity rates higher than 30% of the population.  Dietary changes, like increases in portion sizes and increases in sugar consumption, have been reported to be partly responsible for this increase in obesity.

Sugar consumption, both the amount consumed and the type consumed, has been a focus of serious and sometimes heated debate in regards to its importance to our current obesity epidemic.  This is due to the fact that sugar, particularly added sugar, has the potential to lead to excess calorie consumption.  Despite the concerns about dietary sugar, sugars will remain a very common part of our food supply.  Many sugars like glucose, fructose, sucrose, and lactose are natural components of fruits, vegetables, grains, and more.

A recent nutrition study (free to download) examined changes in energy, total sugar, and added sugar intakes from the 1970s to the 1990's using the NHANES I and NHANES III data sets.  According to the authors of this study, many previous studies assessed dietary changes on a per capita basis, which does not always take into account amounts of food purchased and consumed.  In hopes of getting a clearer picture of dietary changes, the investigators assessed dietary changes using the NHANES data, which assessed actual food consumption and has previously been used to show the nations increase in obesity.  The results of this analysis provided some interesting information...

Energy Intake:  Total energy intake increased from the 1970s to the 1990s by 144 Calories per day on average.  Interestingly, calorie intake decreased by about 56 Calories per day in people 18 years of age or younger, while people over 18 years of age increased calorie consumption by a whopping 226 Calories per day on average.

Total Sugar Intake:  Total sugar intake, which includes added sugars, increased by 10 grams per day on average.  Average total sugar intake did not increase in people 18 years of age or younger, but increased by 14% in people over 18 years of age.

Added Sugar Intake:  Similar to total sugar intake, added sugar consumption increased by 9 grams per day on average with adults over 18 years age showing the greatest increase (18% or 13 grams per day more in the 1990s than in the 1970s!) in added sugar consumption.

Total Carbohydrate Consumption:  While increases in total sugar and added sugar were evident, the increase in total carbohydrate intake was even greater.  From the 1970s to the 1990s total carbohydrate intake increased by 40 grams per day overall with an increase of 15 grams per day in individuals 18 years of age or younger and an amazing increase of 53 grams per day (25%)  in people over 18 years of age.

However, not everything looked bad.  While carbohydrate and sugar intake increased, total fat consumption remained steady and actually decreased when looked at as a percentage of total energy intake.  Additionally, saturated fat and cholesterol intake decreased, while dietary fiber increased from the 1970s to 1990s as did intake of several vitamins.  Interestingly, while sugar intake increased, it actually decreased when examined as a percent of total carbohydrate intake.  According to these study investigators, previous research studies using per capita data might have substantially over-estimated sugar consumption.

According to the study investigators, the biggest change linked to the increase in total calorie consumption was the dramatic increase in the consumption of foods classified as "mixtures of mainly grain", which included food items like burritos, tacos, pizza, egg rolls, spaghetti, rice, other pastas, and frozen meals where the main course is a grain mixture.  Regular carbonated soft drinks, remained the biggest source of added sugars regardless of the age of the population of the decade examined.  In fact, total sugar intake from soft drinks increased by over 40% from the 1970s to the 1990s.

This is an interesting paper with quite a bit of information in it about our dietary changes that I've not discussed here, making it a good read if you have the time to spare.  Based on this study, consumption of total sugars, added sugars, and total carbohydrates have increased from the 1970s to the 1990s, but the increase in carbohydrate consumption was dramatically greater than the increase in sugar consumption.  These data and the study authors suggest that the increase in "mixtures of mainly grain", which are present in common frozen and fast food meals, might be the major contributor to excess calorie consumption and the rise in obesity rates since the 1970s.  With the increasing abundance of these foods, it becomes more important for each of us to be nutritionally aware and make healthy choices whenever possible.  While sugar and carbohydrate intake has increased, we can counteract that to some degree by choosing low glycemic options.  By targeting low or even medium glycemic foods, we can minimize rapid blood sugar changes and gain better control of our food cravings and eating habits.

Reducing Belly Fat Might Reduce Risk of Dying!

There are lots of names for it (pot belly, belly fat, etc.), but no matter what we call it abdominal obesity is dangerous to our health.  Numerous research studies have reported that abdominal obesity, or excess belly fat, has been linked to poor heart health, poor blood sugar health, and chronic inflammation.  It has also been shown that a large waist size is linked to an increased risk of death regardless of one's body mass index (BMI).  However, the effect of a large waist size within different BMI categories remained less clear until a new obesity study published in the recent issue of Archives of Internal Medicine.

For their study, obesity researchers analyzed data from over 48,000 men and over 56,000 women who took part in the Cancer Prevention Study II Nutrition Cohort.  Associations between deaths from 1997 - 2006 and waist size were examined after adjusting for BMI and various other risk factors.  The obesity investigators reported that:

• Very large waist sizes (> 47 inches in men and > 43 inches in women) increased the risk of death by more than 2 times.
• In men, an increase of about 4 inches in waist size was linked to an increased risk of death for those with a normal BMI (16%), overweight BMI (18%), and an obese BMI (21%).
• In women, a similar increase in waist size was also linked to an increased risk of death in all three BMI categories; 25% increased risk in normal BMI, 15% in overweight BMI, and 13% in obese BMI.

This new obesity study emphasizes the importance of getting rid of belly fat and maintaining a healthy waist size, regardless of one's body mass index!  Research suggests that abdominal obesity is particularly dangerous because it is linked with the development of fat tissue around internal organs.  According to the National Institutes of Health, a waist size over 35 inches in women and over 40 inches in men are linked to poorer health.  This new study expands upon that information indicating that very large waist sizes are linked to an increased risk of death.

Of course, the most interesting part of this study is the fact that this increased risk of death with increased waist size was even seen in men and women with a normal body mass index.  Therefore, even if one has a healthy body weight for their height, an overly large waist can still negatively impact their health.  The exact reasons for this are currently unclear and will require further research.  This finding may also add fuel to the debate on whether body mass index or waist:hip ratio are better measures of overall health.  In either case, be sure to make waist size an important part of your weight loss or weight control strategies.

Obesity Linked To Poor Omega-6 to Omega-3 Ratio

Dietary fats are often misunderstood and as a result are often grouped together as a bad part of our regular diets.  For years we were told that limiting the amount of fat in the diet was the right way to eat for both weight management and heart health.  While this is still correct to a point (eating too much fat is still not good for us), we have learned that eating healthy consists of choosing the right fats in the correct amounts.  Fats are an essential part of a healthy diet.  They supply energy and are vital for the absorption of the fat-soluble vitamins A, D, E, and K.  Fats also are important for the normal operation of many of our body's functions.  Unhealthy fats consist of the saturated fats and trans fats, which have been linked to poor heart health.  In contrast, the monounsaturated and polyunsaturated fats are considered healthier fats.  Interestingly, research over the last several years suggests that even the healthy fats need to be consumed in appropriate proportions.

A new obesity research paper explored the impact of a Western diet, which typically has an unhealthy ratio of omega-6 to omega-3 polyunsaturated fats, on obesity over several generations of mice.  For this study, the obesity researchers fed male and female mice a high fat diet (35% of total calories).  This high fat diet  consisted of a high ratio (28:1) of omega-6 fat (linoleic acid) to omega-3 fat (alpha-linolenic acid) and was fed over four subsequent generations.  Consumption of this unbalanced, Western diet resulted in an increase in fat mass over the four generations.  Additionally, changes in fat tissue genes and protein production, particularly those involved in inflammation, were observed throughout the generations of mice consuming this unbalanced diet.  These researchers concluded that even in a population with genetic stability and an unchanging routine, consumption of an unbalanced, high fat diet leads to greater incidence of obesity.

The results of this study appear to reflect the unbalanced diets we typically consume and the rise in obesity seen over the last 20 years or more.  According to some researchers, human beings originally consumed a diet with a 1:1 ratio of omega-6 to omega-3 fats.  Unfortunately, a typical Western diet now contains a ratio of approximately 20:1 omega-6 to omega-3 fats.  This unhealthy ratio of omega-6 to omega-3 fats has arisen through both the excessive consumption of omega-6 fats and insufficient consumption of omega-3 fats.  Current research efforts suggest that dropping back down to a ratio of less than 4 parts omega-6 to 1 part omega-3 has many healthy benefits and that increasing omega-3 consumption is a critical part of re-balancing our dietary fat intakes.  This new obesity research study explored the omega-3 fatty acid alpha-linolenic acid.  The current recommendation for alpha-linolenic acid consumption is between 1.1 - 1.6 grams per day and can be obtained from a variety of plant sources including flaxseed, soybeans, walnuts, and olive oil.  When designing your healthy eating plan, remember to not only aim for healthy fats but for the right balance of healthy fats.

Aim For A Lower Glycemic Index

The glycemic index measures the impact of a food on a person's blood sugar levels.  A food with a high glycemic index causes a rapid rise in blood sugar, while a low glycemic food will not.  Numerous research studies have reported that following an overall low glycemic diet appears to have a variety of health benefits.  In regards to obesity, some studies have suggested that a diet with a low glycemic index typically has a better nutritional profile and might help improve weight control.

A new obesity research study explored the impact of the dietary glycemic index on the body mass index (BMI) and waist size of children (6-11 years of age).  For this study, obesity researchers measured the body weight, waist size, and BMI of more than 3,700 Italian school children and asked their parents to fill out a food frequency questionnaire designed to measure the types and amounts of foods and drinks consumed during the previous year.  Based on the responses to the dietary questionnaire, the study investigators calculated the glycemic index and glycemic load of each child's diet as well as their nutrient intake.  The relationship between each child's dietary habits and body measurements were analyzed.  These obesity researchers reported that:

• Children grouped into the highest quarter of glycemic index measures had the highest body mass index and highest incidence of obesity with almost a third of these children being obese.
• Over 25% of the children in the top two glycemic index levels were considered overweight.
• An increasing glycemic index value was linked to an increase is waist size.
• A high glycemic index diet was linked to increased intake of energy, carbohydrates, and fiber and decreased intake of dietary fat.

Overall, the results of this new obesity research study showed that consuming a diet with an overall high glycemic index was linked to increased body weight, waist size, and obesity risk in children. These results emphasize the importance of avoiding an overall high glycemic index diet. Previous research has also suggested that following a low glycemic diet might be important for healthy weight management due to its ability to support normal blood sugar health and to suppress hunger.

Following an overall low glycemic diet does not necessarily mean avoiding all foods that have a high glycemic index.  In fact, some fruits (watermelon) and vegetables (some potatoes) have been reported to have a high glycemic index, but these can still be a nutritious part of an overall healthy diet.  Instead of trying to avoid all high glycemic index foods, a better approach would be to aim for a healthy balanced diet that includes plenty of low glycemic or medium glycemic index foods.  By doing this, even if you have the occasional high glycemic item, your overall diet is more likely to remain at a low or medium glycemic index level.  The Glycemic Index has a searchable database of foods and their glycemic index values, making it easier to aim for a lower glycemic diet.

Resveratrol Might Help Prevent Weight Gain

Resveratrol, an antioxidant phytochemical found in the skins of red grapes, red wine, and purple grape juice as well as other foods, has been implicated in a number of possible health benefits, particularly heart health.  Emerging research continues to suggest that resveratrol might have anti-obesity benefits.  In fact, one recent human cell culture study suggests that resveratrol modifies the growth, development, and function of human fat cells.  However, the vast majority of this research to date has been done in rodents or cell culture systems.

A new obesity research study (free to read) examined the potential weight control benefits of resveratrol in a non-human primate (grey mouse lemur) model of obesity.  For this study, obesity researchers fed resveratrol to the lemurs for 4 weeks during their winter period of natural weight gain.  Changes in body weight, food intake, metabolic rate, hormone profiles, daily activity, and more were examined.  The obesity researchers reported that:

• Weight gain was suppressed from about 6% to 1% after the addition of reseveratrol to the lemur's diet.
• Addition of resveratrol to the diet reduced overall food consumption by 13%
• The resting metabolic rate of the lemurs fed resveratrol for 4 weeks increased by 29%.

These are interesting results that continue to support the possible weight control benefits of resveratrol.  Based on this new animal study, resveratrol appears to support weight control by reducing food consumption and increasing metabolism, thereby altering the ratio of 'calories in' versus 'calories out' in a beneficial direction.  Since resveratrol did not have any impact on levels of gut hormones involved in appetite suppression, the reason for the reduction in food consumption appears uncertain in this study.

While the weight loss or weight control benefits of resveratrol continue to get a lot of attention, the actual research in human volunteers remains sparse.  However, one new study in the Journal of Clinical Endocrinology and Metabolism reports that resveratrol has anti-inflammatory actions in human subjects and according to ClinicalTrials.gov a number of resveratrol obesity-related studies are in progress.  Therefore, we might have a clearer picture of resveratrol's weight control benefits in the near future.  In the mean time, resveratrol appears to have possible anti-inflammatory and antioxidant benefits and can be found in a number of foods that can be included as part of a healthy diet.

Following a diet plan or weight control plan can be difficult for many of us.  Including delicious tasting foods in my diet plan makes it easy to follow and maintain long-term.  Visit us at www.drtabor.com to learn more!

Snacking Linked to Reduced Obesity Risk In Children?

A new obesity study published in the American Journal of Clinical Nutrition reports that snacking is linked to a decreased risk of being overweight and a decreased risk of abdominal obesity.

Upon reading that, many of us are probably thinking that these results make no sense.  After all, wouldn't it make more sense that snacking would increase one's risk for obesity if for no other reason than snacking would increase the amount of calories consumed?  Apparently, the impact of snacking on obesity risk in children is understudied and the results have been inconsistent to date.  Some studies have reported that frequent snacking between meals increases obesity risk, while other studies suggest that consuming several small meals throughout the day instead of relying on 1-3 main meals per day helps with weight control.

This new study examined nutrition and body weight data from the National Health and Nutrition Examinaton Survey (NHANES) between 1999-2004.  For this study, teens were categorized based on the number of snacks they ate per day and their percent of total energy intake from snacks.  Differences in various weight measures between these groups were analyzed.  The study investigators reported:

• Increasing levels of snacking by teens was linked to lower body weights, reduced percentage of overweight or obesity, and smaller waist size in addition to reductions in other weight measures.
• The risk for overweight or obesity was reduced by about 60% in teens eating more than 4 snacks per day.
• Eating more than 4 snacks per day was also linked to about a 60% decreased risk for abdominal obesity.
• Similar results were observed when snacking was examined as a percentage of total dietary intake.  Consumption of snacks at a level greater than 20% of total energy was linked to reduced risk for overweight and abdominal obesity.  

These are both interesting and somewhat puzzling results that will probably continue to fuel the debate regarding snacking frequency in teens and weight control.  These inconsistencies are liable to be due to such things as the types of snacks consumed and whether beverages are included in a study's definition of snacking.  If the snacks being eaten are of poor nutritional quality (high in energy, low in nutrients), then snacking might have the potential to increase obesity risk.  In contrast, if the snacks are healthier and nutrient rich, then snacking might have weight management benefits.  This new study does not appear to mention if the types of snacks were determined.  Instead, this new study appears to be looking at snacking as a general eating pattern regardless of the types of snacks consumed. While nutritionists and other food researchers continue to explore the impact of snacking on weight management and obesity, it is best if we all choose healthy snack options.  This could be as simple as choosing fruits and vegetables for snacking or taking the time to look for snacks that have more protein and carbohydrates than fat content.

Snacking can be a great way to curb mid-morning, mid-afternoon, and late evening hunger.  Each serving of my Crispy Lace Non-Naughty Nibbles contains 7 grams of protein, 2 grams of fiber and only 100 calories, making them a delicious snacking option.  Visit us at www.drtabor.com to learn more about my delicious foods!

A New Diet Pill On The Horizon?

Diet pills are extremely popular for many individuals trying to lose weight, though the success of most of the pharmaceutical weight loss pills has been dampened by their safety profile.  Many of the popular diet pills, like fenfluramine, dexfenfluramine, and sibutramine, have been removed or are in danger of being removed from the market due to safety concerns.

According to a new weight loss study published in the New England Journal of Medicine, a new drug, lorcaserin, successfully helps with weight loss without the safety concerns of previous diet pills.  In this study, investigators randomly assigned  over 3,000 overweight or obese adults to receive either a lorcaserin diet pill or a placebo pill twice daily for 1 year.  After completion of the first year, individuals who had received the lorcaserin were re-assigned to either continue taking lorcaserin or take the placebo pill for a second year.  All study volunteers received regular counseling to exercise moderately 30 minutes each day and to consume 600 fewer Calories per day.  Weight loss was examined after the first year and weight maintenance was determined after the second year.  The study investigators reported that:

• Volunteers taking lorcaserin lost 13 lbs on average after 1 year, while volunteers taking the placebo pill lost only 5 lbs on average.
• 47.5% of volunteers taking lorcaserin lost more than 5% of their body weight compared to only 20% of volunteers taking the placebo pill.  
• During the second year of the study, 68% of the study subjects taking lorcaserin maintained their weight loss for a year.  Only 50% of the subjects taking the placebo pill managed to maintain their weight loss after a year.
• Side effects of lorcaserin use were considered mild and included headache, dizziness, and nausea.  Furthermore, use of lorcaserin was not linked to increases in heart valve problems.

At first blush, these look like excellent results.  Study volunteers taking this new diet pill lost weight, maintained their weight loss, and, compared to control subjects, experienced no differences in serious side effects.  However, I keep coming back to that average 13-lb weight loss. Volunteers in the lorcaserin group exercised 30 minutes per day, consumed 600 fewer calories per day than they needed, and took lorcaserin twice daily, all of which resulted in an average loss of 13 lbs in one year.  If you look at that number another way, that would be equal to an average of 1/4 lb per week.  How many of us would be happy losing only 1/4 lb per week?

According to an article on the Mayo Clinic website, cutting 500 calories per day (3,500 calories per week) from your typical diet will result in losing 1 lb per week.  The volunteers in this study were supposed to consume 600 calories per day (4,200 calories per week) less than their energy needs and yet they only lost 1/4 lb per week on average.  This could suggest that either the study volunteers weren't exercising and dieting according to the instructions or the diet pill wasn't as effective as it appears.  A previous study of this same diet pill showed that it could help with weight loss in individuals following their regular diet and activity plans, suggesting that diet and exercise might not be needed when taking this diet pill.

Since this drug works by decreasing food intake, it might be possible that weight loss could be achieved without additional dieting and exercise; however, an average weight loss of 13 lbs per year does not seem as effective as diet and exercise alone can be.  For example, dieters lost nearly 400% more weight on my diet's eating and physical activity plan when compared to another study of dieters who used a leading weight loss diet pill plan. You can lose more weight in less time on my diet plan without using diet pills; however, if with your doctor’s consent you choose to use a diet pill, my eating and physical activity plan is the perfect complement for the best results.

Don't Let Your Workouts Slow You Down!

Regular exercise, outside of our normal daily physical activities, is a vital part of maintaining a healthy lifestyle and a healthy body weight. The 2008 Physical Activity Guidelines for Americans recommends that we should exercise more than 300 minutes per week of moderate-intensity exercise or more than 150 minutes per week of vigorous-intensity exercise, though less than half of us meet these recommendations.

Research studies have suggested that committing to a regular, structured exercise program might cause us to reduce the amount of physical activity we get during the rest of the day, partially compensating for our daily workout.  Whether our choice of exercise intensity impacts our overall daily amounts of physical activity remains unclear and is the subject of a new obesity research study. 

For this new study (free to download), research investigators enrolled 36 overweight or obese postmenopausal women who had been inactive during the 6 months before the study started.  Eighteen of the women were assigned to moderate-intensity exercise and the other 18 women were assigned to vigorous-intensity exercise such that calories burned were similar in both groups of women.  Total physical activity (structured exercise + normal daily activities) was measured both on days with structured exercise and on days without structured exercise.  The results of this investigation were very interesting.

Moderate-Intensity Exercise.  In women exercising at a moderate intensity, the amount of energy burned was higher on days when they exercised (~577 Calories) than on days when they did not exercise (~450 Calories).  However, this difference between exercise and non-exercise days (~127 Calories) was substantially less than the calories burned on the treadmill, suggesting that the women burned less calories outside of their workout on days that they exercised.

Vigorous-Intensity Exercise.  In women exercising at a vigorous intensity, the amount of total energy burned was LESS on days with treadmill exercise (~450 Calories) than on days without treadmill exercise (~520 Calories), suggesting that the women in this study were reducing the amount of physical activity they did outside of the structured program on days they exercised.

These are fascinating results that suggest we might automatically compensate for any structured exercise program to which we commit if we are not careful.  According to this study, the greatest risk appears to come with vigorous-intensity exercise.  In this group of women, those that committed to vigorous-intensity exercise on average reduced their non-treadmill physical activity so much that they burned more calories on non-exercise days than they did on exercise days.  While this reduction in non-treadmill physical activity was seen in both groups of women, it was clearly more pronounced in women following a vigorous-intensity program.  These findings make it clear that we need to educate individuals deciding to start a structured exercise program about the importance of maintaining their normal levels of physical activity in addition to their exercise program in order to achieve the best possible results.

Walking 30-45 minutes per day is a great way to start a healthy exercise and weight loss plan.  Visit us at www.drtabor.com to learn more about my easy diet plan and physical activity plan.

Berberine Blocks Fat Production in Obese Mice

Berberine is chemical found naturally in plants such as Berberis (a shrub) and Goldenseal (a member of the buttercup family).  It has been used in traditional herbal medicine to treat bacterial and fungal infections.  Research into the potential health benefits of berberine suggests that it might have heart health and other benefits.

A new obesity study was conducted in mice to determine if the potential anti-obesity benefits of berberine seen in cell culture studies might also be evident in an animal model of obesity.  For this study, obesity researchers treated mice being fed either a normal diet or a high-fat diet to induce obesity with berberine.  The results of this study showed that:

• Berberine reduced weight gain in obese mice fed a high fat diet.
• Food intake by obese mice was reduced by treatment with berberine.
• Berberine had beneficial effects on markers of cholesterol health and blood sugar health.
• Treatment with berberine did not have any negative effects on mice fed a normal diet.

These are interesting results suggesting that this naturally occuring plant chemical might have potential weight management benefits.  Previous research indicates that berberine's possible benefits are likely due to its anti-inflammatory activities and its ability to reduce production of fat by fat cells.  Additional research will be needed to test the potential anti-obesity benefits of berberine in human clinical trials.  While appropriate levels of exercise and food consumption remain the cornerstone of maintaining a healthy body weight, new discoveries that can help fight the current obesity epidemic are always welcome!
