There are differences of opinions on whether one should go for fasting as an aid to weight loss or not. During fasting, a process called Ketosis occurs. Mild ketosis is not harmful. Due to this process, accumulated fat in the body gets dislodged and is burnt away. This is useful as reduction is fat can't be done without 'ketosis'. Bad habits of eating and living are generally responsible for obesity which fastng can't eliminate.

During the period of fasting few steps must be taken to ensure intake of vitamins, minerals. If this is not taken care of body starts depleting, which is very undesirable. Thus there must be an end to fasting at some stage. At this stage, there is every chance of gaining the lost weight and the fat. For these reasons some experts are of opinion that fasting should not be done in weight reduction but it may help gain some control over your diet. Doctors advise to go for better eating habits than to go for fasting.

It has been studied that the reduction in weight is more if a person continues to eat some amount of food than fasting altogether. This helps to those who eat something because of the increased basal metabolic rate. Short term fating has been noticed as useless in shedding extra fat.

Under normal circumstance, fasting is not advisable for weight loss. However, for getting rid of stubborn obesity which does not yield to other remedial measures, long term fasting can help but should be carried out under medical supervision. In period of fasting, one must ensure sufficient water intake or lemon juice to protect against problems created by severe fast.
