Winter burns fat naturally.
Feeling to lazy to go out for a jog in winter? The good news is u need to spend half the effort in winter to burn calories. Just go out for a walk and expose yourself to cold. Your body has 2 kinds of fat, white fat which messes the body up and brown fat which is a calorie burning fat. When u go out in cold, body favours brown fat over white, which in-turn burns more calories than in summer. Shivering for 10 minutes on the other hand will burn calories equivalent to a hours worth of exercise.
