After somewhere between three and five hours, your body stops processing its last meal. There's nothing left to absorb, so insulin levels naturally decrease. Then, somewhere between eight and 12 hours after that last meal, your body starts burning stored fat. (Why don't you start burning fat sooner? Biology is sometimes a pain in the ass; it's like our bodies will do anything to hang on to fat.)
Ultimately, you need to pick a healthy eating plan you can stick to, Stewart says. The benefit of a low-carb approach is that it simply involves learning better food choices—no calorie-counting is necessary.

3. Doing Bicycles not only help to melt belly fat it also works on the muscles of your upper body. For this you have to lie on your back and raise your legs at 90 degree, then bend your legs to 90 degree and hold it. Keep your hands under your head and slowly raise your head and shoulder off the ground. Now with a fast movement bring your right elbow to your left knee and extend your right leg in the front. You have to switch sides fast to create the cycling effect. Use your core muscles to keep your head and shoulder above the ground throughout the exercise. Do 20 repetitions and add 10 as you become stronger.
