How many eggs can I eat a day?

From a calorie perspective, 2-3 eggs per day fits comfortably in most weight loss plans (1,200-1,800 cal/day). That's 144-216 calories. Current research shows no significant health risk from eating up to 3 whole eggs daily for most healthy adults.

Are egg whites healthier than whole eggs?

Egg whites are lower in calories (17 vs 72 per egg) and fat (0.1g vs 4.8g), but you lose half the protein and nearly all the vitamins. For weight loss, whole eggs are usually the better choice because the yolk's nutrients and fat keep you fuller longer.
