WEB DESK: You can crunch yourself into a coma and still have ab flab. If you really want a sleek, sexy midriff, you've got to tweak your diet. All of the best waist-whittling foods contain fiber to banish bloat, antioxidants to boost your abs routine's effectiveness, and protein to help maintain a healthy metabolism.

Here, the top six choices for flatter stomach:

1. Almonds

An ounce a day (about 23 almonds), with approximately 160 calories. An empty Altoids tin will hold your daily dose perfectly.

2. Eggs

One egg a day, unless you have high blood cholesterol, in which case you should check with your doctor first. (One egg packs about 213 milligrams of cholesterol.)

3. Apples

An apple (or two) a day. A study published in the Journal of Agricultural and Food Chemistry found that the Red Delicious, Cortland, and Northern Spy varieties had the highest antioxidant activity.

4. Berries

At least half a cup daily, or about 30 calories' worth. Don't limit yourself to the usual suspects, like raspberries, blueberries, and strawberries.

5. Leafy Greens

Three servings daily. Keep a bag of prewashed baby spinach in your fridge and toss a handful into soups, salads, pasta dishes, stir-fries, and sandwiches. When you get sick of spinach, reach for a bunch of arugula, broccoli rabe, or broccolini, a cross between broccoli and Chinese kale.

6. Yogurt

One to three cups a day of low-fat or fat-free yogurt. Choose unsweetened yogurt that contains live active cultures. Add a handful of fresh chopped fruit for flavor and extra fiber.
