Bigger Meals Earlier Can Help Weight Loss

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. (Pepper in lukewarm water is an excellent way to lose weight quickly.)

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.

Average triglyceride levels, an indicator of cardiovascular health, decreased by 34% in BF subjects but increased by 15% in D subjects. Total cholesterol slightly decreased in both groups but HDL levels, the so-called good cholesterol, increased significantly only in the BF group. (Pepper in lukewarm water is an excellent way to lose weight quickly.)

Levels of glucose, insulin and ghrelin, an appetite hormone, decreased significantly in both groups but to a greater extent in BF subjects. 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.

Caveat: The study was too short to determine the long-term health benefits of high-energy intake at breakfast, they said.
