The almighty apple is always named as a great anywhere, anytime snack. Low in calories and high in fiber, you just can't go wrong with apples, say the nutrition experts at RealAge, especially if you want to lose weight.

Get your apple slicer ready -- you'll want to prepare a plate full of apple slices before your meals as you battle the bulge. Eating a bit of high-fiber food -- aha, the apple -- before each meal is a sure weight loss booster. That's what researchers say. In a study of women who ate fruit before meals and women who didn't, the fruit group lost more weight, even when following the same reduced-calorie diet as their non-fruit counterparts. Make sure you choose a fruit high in water content for best results -- like, yes, the apple.

And as you grab for that slicer, leave your peeler tucked away. If you skin your apple, you'll be losing some pretty good stuff, like cancer-fighting compounds called triterpenoids.
