This is really a very simple equation. Your body need certain amount of calories to keep itself going. If your intake provides more than that amount of calories, you gain weight. If your intake is less than this amount, you start losing weight. Isn’t it very simple.
But, this equation is not really that simple. For, if you start eating severely low diet, your body will consider this as starving and will indicate this by making you feel tired and week. And would start pulling energy from your stored fat and from your muscle tissues as well. So, dieting alone should never be practised for weight loss.
So, a regular exercise program is needed in addition to eating less. This will make your body system such that it will pull energy from stored fat resources not the muscle tissues. Rather, the muscle tissues will be more perfectly built. And, you will be losing weight by reducing the unwanted tires not from your muscles.
