In further research about the timing of eating meals, it seems that skipping breakfast has been shown to be as bad as your mother told you it would be. Contrary to earlier reports that suggest skipping breakfast leads to an inability to catch up on the number of calories eaten during the day (thus promoting weight loss), skipping breakfast and overeating in the evening have been shown to play a significant role in weight gain and obesity.
From June to October 2012, researchers at Tel Aviv University in Israel recruited 93 overweight and obese women to participate in a three-month, 1,400-calorie-a-day diet, an amount recommended in some weight-loss diets. The women were in their mid-40s and had metabolic syndrome, the term for a cluster of health conditions associated with Type 2 diabetes. Half the women were assigned to a breakfast group (BF) that consumed 50% of the allotted daily calories at breakfast, 36% at lunch and 14% at dinner. A dinner group (D) did the opposite, eating 14% of calories at breakfast, 36% at midday and 50% at dinner. Participants were measured for various body and metabolic markers every two weeks.
The BF subjects lost an average 19.1 pounds over 12 weeks, while the D group shed 7.9 pounds. BF subjects trimmed 3.3 inches from their waistlines compared with 1.5 inches in D group; body-mass index dropped 10% and 5% in the BF and D groups, respectively.
The BF group also had significantly lower glucose and insulin responses in post-lunch blood tests, suggesting that eating a relatively high-calorie breakfast helped to maintain stable insulin levels after the second meal of the day, researchers said.
No measurements were given on particular macronutrient content of any of the meals, and with a period of research of less than 6 months the long term effects are presently unknown.
