Obesity

　　Obesity is a global health problem. When human bodies have accumulated excess fat and are unhealthy it can lead to serious illness including heart disease, chronic lethargy and cancer.

　　Drug companies such as Roche have been leading obesity research since the mid-1970s. Specialized hormones were connected to reduced food intake and body weight. One of the latest medicines to improve obese conditions is Xenical. It acts on the digestive system and promotes weight loss from body fat, not muscle.

　　With effective drugs that are safe for long term use on the market, and increased education about diet and exercise, obesity may soon become extinct.
