While in this state, as soon as you eat, the body automatically stores the food in the form of fat and does not burn it for energy. Your body stores because it's not sure when it will be fed again, and while in this self-preservation mode it is only bothered about survival. The body, instead of using up the fat particles stored, raids muscles. And this vicious cycle continues till you put an end to it. You can gain weight just by the way you look at food and eat.
Protein is the most important part of our meals, whether to gain or lose weight.
If you give your body enough protein throughout the day, your body won't look to your muscle for fuel. To make sure you are getting enough protein, double your lean body mass in protein grams. If you weigh 80 kg and your body fat percentage is 15 per cent, your lean body mass should be 68 kg. To sustain your present mass, you must consume at least eat 170 grams of protein a day. Please seek the advice of a competent nutritionist to measure your body fat percentage.
