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!
