Which diet is best for keeping the weight off?

Diet composition does count: those eating fewer carbs burn more energy, researchers say

A low-carb diet could help overweight patients maintain weight loss, especially if they have high insulin secretion, new research shows.

Despite being on equal-energy diets, those on a low-carbohydrate diet burn more energy than those on higher amounts of carbohydrate, according to the study in the BMJ.

“Consistent with the carbohydrate–insulin model, lowering dietary carbohydrate increased energy expenditure during weight-loss maintenance,” say the researchers from Harvard Medical School, US.

“This metabolic effect may improve the success of obesity treatment, especially among those with high insulin secretion.”

The researchers want to see whether dietary composition affects energy expenditure in people who have already lost weight.

“With weight loss, hunger increases and energy expenditure decreases — physiological adaptions that defend against
