You can crunch as much you can but without proper diet it is impossible to get those perfect abs you have been looking for. If you really want good and killer abs you have  to alter your diet. All of the  foods  that work on slim waist contain fiber to banish bloat, antioxidants to boost your abs routine’s effectiveness, and protein to help maintain a healthy metabolism. 

Here are  the top ten healthy food  for  absolutely flat abs.

  • Eggs-

Eggs

You won’t find a more perfect protein source. Eggs are highly respected by dietitians because of their balance of essential amino acids (protein building blocks used by your body to manufacture everything from muscle fibers to brain chemicals). 

Try 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.)

  • Quinoa-

Quinoa

 Pronounced as ( 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.It is now easily available in the supermarkets.

Try at least one half-cup serving (a third of your whole-grain requirements) per day. 

  • Almonds-

Almonds

are delicious and versatile nuts contain filling protein and fiber, not to mention vitamin E, a powerful antioxidant. They’re also a good source of magnesium, a mineral your body must have in order to produce energy, build and maintain muscle tissue, and regulate blood sugar. The composition of their cell walls may help reduce the absorption of all of their fat, making them an extra-lean nut.

  • Soy-

Soy

Soybeans are a great source of antioxidants, fiber, and protein. Plus, they’re incredibly versatile. Snack on dry-roasted soybeans, toss shelled edamame into soups, and slip a spoonful of silken tofu into your morning smoothie. Liquid soy also makes a good meal replacement.

Try  twenty-five grams of whole (not isolated) soy protein daily. A half cup of steamed edamame contains about 130 calories and 11 grams of protein. Four ounces of tofu (94 calories) contain 10 grams. Choose whole soy foods over products packed with “isolated soy protein” — the latter may not provide all the benefits of whole soybeans.

  • Apples-

Apples

 A large apple has five grams of fiber, but it’s also nearly 85 percent water, which helps you feel full. Apples also contain quercetin, a compound shown to help fight certain cancers, reduce cholesterol damage, and promote healthy lungs.

  • Berries-

Most are loaded with fiber, every dieter’s best friend. The more fiber you eat — experts say that it’s best to get between 25 and 35 grams every day — the fewer calories you absorb from all the other stuff you put in your mouth. That’s because fiber traps food particles and shuttles them out of your system before they’re fully digested. Berries (and other fruits) are also high in antioxidants, which not only help protect you from chronic diseases like cancer but may also help you get more results from your workouts. 

  • Yogurt-

Yogurt

People who get their calcium from yogurt rather than from other sources may lose more weight around their midsection.The probiotic bacteria in most yogurts help keep your digestive system healthy, which translates into a lower incidence of gas, bloating, and constipation, which can keep your tummy looking flat.

Try  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.

  • Veg soups-

Veg soup

 people who eat broth-based (or low-fat cream-based) soups two times a day are more successful in losing weight than those who eat the same amount of calories in snack food. Soup eaters also maintained, on average, a total weight loss of 16 pounds after one year. 

Try at least one cup of low-calorie, low-sodium vegetable soup every day.

  • Fish-

Fish

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,  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.

  • Green Leafy Vegetables-

Green Leafy Vegetables

Their cancer-preventing carotenoids won’t help shrink your waistline, but their low calorie count definitely will. One cup of spinach contains only about 40 calories, while a cup of broccoli has 55 calories and satisfies 20 percent of your day’s fiber requirement. Most leafy greens are also a good source of calcium, an essential ingredient for muscle contraction. In other words, they help fuel your workouts.Try for: 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.
