Lose Belly Fat With These 28 Super Delicious Foods, Scientifically Proven

ONIONS AND LEEKS

While probiotics encourage the growth of good bacteria, prebiotics feed the ones you already have. When you eat prebiotic foods like onions and leeks, they produce butyrate, a metabolic wonder drug that improves insulin sensitivity and increases the amount of fat you burn, says Rafael Kellman, M.D., author of The Microbiome Diet. Now that it’s summer, pop either on the grill to bring out their sweetness. Drizzle with olive oil, salt, and pepper and cook until golden.

JICAMA

This Mexican root vegetable contains inulin, a type of fiber that slows down the absorption of blood sugar to help you feel fuller longer, Kellman says. It’s also high in magnesium and manganese, two vitamins needed for digestive enzymes to function at their peak. Add chopped jicama to give salads a nice crunch or shred it in your favorite summer slaw.

WATER WITH LEMON

Lipman suggests sipping it as soon as you wake up and after each meal. “Bitter foods like lemon help stimulate your body’s GI juices and aid the start of the digestion process. When digestion is robust, your body breaks down food better and absorbs more of its nutrients, both of which help you maintain a healthy weight and flat belly.” Arugula, dandelion root, and apple cider vinegar will also do the trick, so munch on a salad with these greens before your main course — bonus if it’s dressed with cider vinaigrette.
