The 10 Best Foods for Flat Abs

Salmon and Quinoa

Seafood, especially fatty fish like salmon, tuna, and mackerel, is an excellent source of omega-3 fatty acids. These uber-healthy fats may help promote fat burning by making your metabolism more efficient, according to Kleiner. An Australian study showed that overweight people who ate fish daily improved their glucose-insulin response. Translated, this means that seafood may help slow digestion and prevent cravings. If that doesn't hook you, consider this: Seafood is an excellent source of abs-friendly protein.

Try for: Two four-ounce servings per week. Wild salmon, though pricey, contains more omega-3 fatty acids than farm-raised. (If it doesn't say wild, it's farm-raised.) If seafood's not your thing, you can get your omega-3's from flaxseed (grind and sprinkle on your cereal) or walnuts.

Never heard of it? Pronounced KEEN-wah, this whole grain contains 5 grams of fiber and 11 grams of protein per half cup. Cook it as you would any other grain (although some brands require rinsing). Quinoa's nutty flavor and crunchy-yet-chewy texture are like a cross between whole-wheat couscous and short-grain brown rice.

Try for: At least one half-cup serving (a third of your whole-grain requirements) per day. Try substituting AltiPlano Gold brand instant quinoa hot cereal (160 to 210 calories per packet), in Chai Almond and Spiced Apple Raisin, for oatmeal. Look for it in health-food stores.
