Diet drinks and diet pills that are used as meal substitutes do help in reducing weight, but as soon as the user stops taking them, he again starts gaining weight. There are a lot of other nutritional programs, products, and formulas such as Herbalife Nutritional Program, Mega-Thin 100 Formula, Nestlé’s Sweet Success, Ultra Slim Fast, Products Containing Chitosan, Supplements Containing Chromium, Products Containing Green Tea Extract, Algae Tablets, St. John's Wort Supplement or Glucomannan Products most of which must be taken before each meal. However, either these products are not effective enough or safe. Most of them are very expensive and as soon as their use is discontinued, the user resumes weight gain.
A lot of research has been done in this area and researchers are coming up with many weight loss products every day. Most physicians recommend good weight loss products with minimum side effects to overweight and obese people to help them get back to shape and avoid developing chronic diseases like diabetes or heart related problems. Anti-obesity drugs or weight loss pills such as fenfluoramine, ephedra, nicotine or cocaine help in losing weight directly through suppression of appetite and increase in the body's metabolism. These drugs also interfere with the body's ability to absorb specific nutrients in food. However, the continued use of weight loss pills can cause serious side effects, physical illness or disorders, such as heart valve disease, pulmonary hypertension etc. Moreover, prolonged unsupervised use of amphetamines causes addiction, tachycardia and hypertension.
A lot of people who are overweight either lack the attitude or the time or the will to work towards weight loss. Sustained weight loss and maintenance has no shortcuts. One must resort to healthy and nutritious low-calorie diet along with moderate exercises in order to get back a well-toned shapely body and a feeling of well-being.
