People who want to lose weight commonly, and first of all, think about reducing the amount of food they eat. This may be quite a solution but not exactly the best there is. In fact, depending on the amount you reduce in your food intake, it may even be dangerous to one's health.
Children, adolescents, pregnant or breast feeding women, should not follow very low calorie diet plan unless as a part of a specialized obesity treatment program. The only candidates for very low energy diets are those suffering from moderate to severe obesity, who are at risk from weight-related illness and these risks are worse than the potential side effects of a very low-calorie diets, and this is when doctors prescribe them.
The problem comes when only mildly overweight people begin to use them as a quick fix. Sudden dietary changes forced upon your body your body can wreak havoc, and more often than not you can end up back where you started.
Very low-calorie diet is also compensated for by the body by burning muscle. People on this type of diet who revert back to their old eating habits end up gaining back some, if not all the weight they have shed off. This would consist mainly of fats. And since fats have more volume per mass than muscle, they end up having the same weight as before but more bulkier. In losing weight, one should keep in mind that they should lose excess body fats only.Muscle loss is extremely unhealthy (do you afford to lose heart muscles?).
These diets do not change long established bad eating patterns and cause the body to slow down their metabolism significantly, so when the dieter returns to a more normal eating pattern - which is unavoidable - their slower metabolism generally leads to increased weight gain.
Apart from the minor side effects that disappear within weeks like fatigue, nausea, constipation and diarrhea, there are serious side effects like gall stones.
In the absence of a special factor, successful treatment of obesity requires a long term commitment to improved dietary and exercise habits.SO these very low -calorie diets are not likely to be effective.
Fad diets, unbalanced diets, diet pills, diet supplements, weight loss surgery and other short term weight loss methods are not recommended for permanent weight control.
The best way to lose excess fat and maintain a healthy weight in the long term is to follow a balanced calorie controlled diet ( slightly less than your basal metabolic rate, i.e.about 2000-calories/day)and take regular aerobic exercise.
