Consuming eggs in the morning can help you lose weight. They are just protein though so you should incorporate some form of carbohydrate (eg. starchy vegetables) so that you get a well rounded meal.
published in the “International Journal of Obesity” in 2008 compared
weight loss in individuals who consumed eggs for breakfast to those who
consumed a bagel. Even though the two groups maintained an identical
caloric deficit during the study, the people who ate eggs lost more
weight and body fat than the bagel group.
If you currently consume a
breakfast rich in carbohydrates, switching to an omelette might promote
weight loss without the need for further food restriction.
