Dieters who eat two eggs for breakfast lose 65 percent more weight, scientists have found.
The eggy start to the day also gave eaters higher energy levels and a greater reduction in body mass index compared with those eating a bread based breakfast.
Researchers from the Louisiana State University monitored two group of overweight adult, one group ate two eggs each morning the others a bagel (with the same number of calories and had identical weight.)
Both groups were then asked to follow the same diet, but those who had started with the bagel were found to snack and eat more.
"People have a hard time adhering to diets and our research shows that choosing eggs for breakfast can dramatically improve the success of a weight loss plan," said lead researcher Nikhil Dhurandhar.
Dietitian Jackie Newgent, said: "Eggs are a good source of all-natural, high-quality protein, so they can help keep you satisfied longer, making it easier to resist tempting snacks," said Newgent.
"Nearly half of an egg's protein, and many of the other nutrients, are found in the yolk, so make sure to eat the whole egg for maximum benefits."
"Apparently, the increased satiety and energy due to eggs helps people better comply with a reduced-calorie diet."
