Body responses negatively when calories are cut off immediately :-
Body has its own system and it reacts negatively when calorie intake is reduced immediately i.e. when some one is put on a weight loss diet and was made to cut off calorie ...very early. When on a weight loss diet body starts burning less calories as cutting on food threatens the body. It tries to protect itself by slowing rate at which it burns calories at rest i.e. basal metabolism. This makes weight loss harder. To counter this effect it is important to make the changes gradually in your eating habits. Any drastic change is going to result in body reacting negatively to the change and going in hibernation mode. Moreover even a weight loss diet should be nutritionally complete.
