People who eat their biggest meal at breakfast are far more likely to lose weight and centimetres off their waistline, than those who eat a large dinner, according to new research from Tel Aviv University.1
The study, published in the journal Obesity, randomly assigned 93 obese women to one of two groups. Each consumed a moderate-carbohydrate, moderate-fat diet of 1,400 calories a day for 12 weeks. The first group consumed 700 calories at breakfast, 500 at lunch, and 200 at dinner. The second group ate 200 calories at breakfast, 500 at lunch, and 700 at dinner.
At the end of the 12 weeks the “big breakfast” group had lost an average of 8kg each and 7.6 cm off their waistline, compared to a 3kg and 3.5cm loss for participants in the “big dinner” group. Researchers say those eating a big breakfast had less desire to snack, were more satiated and had significantly lower levels of the hunger-regulating hormone ghrelin.
