The egg diet is a high-protein, low to no-carbohydrate diet. So basically, the diet includes 1-2 boiled eggs for breakfast, a piece of fruit for lunch and a small piece of chicken or fish (or more eggs) for dinner. As this is some kind of nutritional fasting where you stop consuming certain nutrients, in this case, carbohydrates, sure you'd probably lose some weight. But it's not really a healthy way to lose weight. Chances are, you'd gain it all back once you get tired of eating almost nothing but eggs. It's not easy but try to modify your lifestyle to lose weight and get healthy. Eat well and exercise - make that your diet plan.
