The eggs have it. What exactly do they have? The power to peel away pounds, that's what.

Poached, scrambled, or sunny-side up, eggs are a do-good diet food. We know this because people in one study on a low-calorie weight loss plan who ate two scrambled eggs with unbuttered toast -- jelly was permitted -- for breakfast lost 65 percent more weight than dieters who ate a bagel with cream cheese.

Here's the point: Eggs are filling, which keeps us satisfied longer, which keeps us from snacking later in the day. Here's the caution: This study featured a low-calorie diet, and this means eating eggs for breakfast works ony if you're watching what and how much you eat for the rest of the day.
