Several studies of overweight women showed that eating eggs instead of bagels increased their feeling of fullness and caused them to consume fewer calories over the next 36 hours. Egg breakfasts have also been shown to cause up to 65% greater weight loss, over 8 weeks (7, 9). A similar study in men came to the same conclusion, showing that an egg breakfast significantly reduced calorie intake for the next 24 hours, compared to a bagel breakfast. The egg eaters also felt more full (16). Furthermore, the egg breakfast caused a more stable blood glucose and insulin response, while also suppressing ghrelin (the hunger hormone) (16). Another study in 30 healthy and fit young men compared the effects of three types of breakfasts on three separate occasions.
