Eggs are one of the healthiest and most versatile foods on the planet. One large egg contains less than 1 gram of carbs and fewer than 6 grams of protein, making eggs an ideal food for a ketogenic lifestyle. An egg diet may offer benefits as conventional ketogenic diets, including weight and belly fat loss.

• Egg and Grapefruit Diet: Eggs are an excellent choice when you follow the keto diet. On this version of the diet, you eat half a grapefruit at each meal with your egg or lean protein. No other fruit is allowed.

• Egg-Only Diet: This version of the weight loss program is a mono diet. Mono diets are extreme, unhealthy weight loss programs where you eat only a single food for an extended period. Dieters on this program eat only hard-boiled eggs and water for two weeks.

• Medical Egg Diet: This version of the egg diet requires that you eat one egg and one piece of bread, three times each day. You can also eat as many fruits and vegetables as you like. 

Eggs are definitely among the few of the healthy comfort food options and it helps to lose weight by restricting calories and promoting ketosis- a metabolic state in which your body uses ketones as a source of fuel.
