Please send us your feedback on this article. The use of anorectic drugs in medicine has always been a highly controversial issue. It is generally accepted that the problem of obesity comes more from behavior rather than genetics. Many doctors believe that diet drugs should not be used, and instead people wishing to lose weight should simply eat less and exercise. The first is that you will only lose weight for three to six months before reaching a plateau.
Weight loss is pretty quick for the first three months for almost all diet and exercise plans.
Even the best diet and exercise plans start to lose their effectiveness after three months and by six months weight loss almost always stops completely. The second problem is making sure you are losing fat and not muscle. Many poor diet and exercise plans induce almost as much muscle loss as fat loss, while a good plan can reduce muscle loss to almost zero. Preserving muscle is key for long-term weight loss. Loss of muscle lowers metabolism - making it very difficult to keep the weight off.
