Researchers from the Medical Research Council rather involved 33 men and women who are overweight. They asked to have breakfast three times in three days with a different portion.
First, breakfast contains 700 calories. Secondly, the breakfast had a 20 percent lower calories than the first day. Then, the third the number of calories from breakfast provided is the first half of the day.
A few hours after breakfast, respondents were offered biscuits and supervised calorie consumption at lunch.
As a result, they were able to have breakfast in small amounts to control appetite and tends to take a portion of which is almost the same as the breakfast at lunch.
"By limiting calories at breakfast, they could cut the intake of 270 calories a day, " said researcher Susan Jebb, as quoted by the Daily Mail.
Researchers also suggest that calorie restriction should not be underestimated. Because small changes can have a large impact for waist circumference.
