The calorie requirement should be reduced to lose weight but how much lower? Many make the mistake of reducing their daily caloric requirement too much too soon. If you do this I guarantee you will lose weight fast, so fast and be healed. If you reduce your calories over what you lose is fluid and muscle tissue, none of the things we lose if we want permanent weight loss.
The caloric requirement needed to lose fat
Sensible weight loss in adults should begin with a reduction of 300 calories than the body requires daily. Then, if progress could be reduced to stop another 200 calories. Thus the body may establish a new balance of power, and do it slowly rather than shock to the body. Doing so helps keep metabolism high, which also means more calories burned.
It is also recommended to exercise (with the approval of a doctor or first) to increase calorie burning. If you rely solely on diet to burn fat you will be disappointed because it is not even half as effective if you implement an exercise program with that reducing your caloric requirements.
The calories should never lose the 1500, and in most cases should remain above. Remember that there are 4500 calories in half a kilo of fat so fat removal will be a gradual process, thus reducing your caloric requirement should also be gradual.
