Eat more calories! ! 200? Seriously? Not even a baby eats them! Eat more fruits and veggies whole grains.. you should go every day to the toilet..stay away from salty and processed foods..and as gymndande above said Pilates and aerobics would help..fix your posture when you walk and sit..and always keep in mind that if you are a girl u will sometimes be a bit puffed at the time of the month...hope I helped keep going ;)
Could be several reasons you might be struggling to exercise away that stubborn belly fat.
It's not so easy to zap fat just where you want it to disappear. The more you exercise and the more fat you lose, the more likely it is that your belly fat will eventually be burned away. You can't choose where and how your body burns away fat. If your body weight and BMI are healthy but your belly still seems flabby, maybe you're focusing on the wrong type of exercises. Aerobic or cardiovascular exercises help burn off fat, but strengthening exercises tone and firm muscles. Do ab-specific exercises like the Plank and bicycle crunches; along with Yoga and Pilates to help tone and tighten your core. Perform your toning exercises every second day; or yoga every day.
You have to create a calorie deficit in order to burn fat. Cutting 500 calories a day is good; but never drop more than a 1000 calories from your diet. You need lean proteins, fiber-rich foods and healthy fats if you're exercising. Restrict sugar, fill up on fruits and vegetables, nuts and seeds for snacks and choose whole-grain products instead of processed white flour foods.
