Saw this over on Alwyn Cosgrove's blog, pretty interesting: Here's a study that was just released last month: Alexander et al. Association of Breakfast Skipping With Visceral Adiposity in Overweight Latino Youth. Obesity (Silver Spring). 2009 May 7. The study compared three groups that consumed IDENTICAL total calories. No breakfast Breakfast occasionally Breakfast every day The researchers concluded that "breakfast omission was associated with increased levels of intra-abdominal fat independent of daily energy intake. Eating breakfast is associated with lower body fat levels in overweight Latino youth. Interventions focused on increasing breakfast consumption are warranted" Another study was presented at The Endocrine Society's 90th Annual Meeting in San Francisco (June 2008) by Jakubowicz MD et al This consisted of two groups that consumed similar total calories (very low - 1200 and 1100). Bothe were low carb diets (group one had 17g of carbs per day and group two had 97g of carbs per day - still considered low carb). The primary difference being that group one consumed a 300 cal breakfast, and group two consumed a 600 cal breakfast After 4 months on each plan there was no significant difference between the groups. However, after 8 months: Group one: 300 cal breakfast - had lost ten pounds Group two: 600 cal breakfast had lost THIRTY-NINE pounds Conclusion of both studies is that eating breakfast, and perhaps a bigger breakfast than usual (therefore eating slightly less calories the rest of the day) could be a useful real world tool for fat loss with clients.
