　　B This is nonsense, says Dr Susan Jebb from the Dunn Nutrition Unit at Cambridge in England. Despite the persistence of this metabolism myth, science has known for several years that the exact opposite is in fact true. Fat people have faster metabolisms than thin people. What is very clear, says Dr Jebb, is that overweight people actually burn off more energy. They have more cells, bigger hearts, bigger lungs and they all need more energy just to keep going.

　　C It took only one night, spent in a sealed room at the Dunn Unit to disabuse one of their patients of the beliefs of a lifetime: her metabolism was fast, not slow. By sealing the room and measuring the exact amount of oxygen she used, researchers were able to show her that her metabolism was not the culprit. It wasnt the answer she expected and probably not the one she wanted but she took the news philosophically.

　　D Although the metabolism myth has been completely disproved, science has far from discounted our genes as responsible for making us whatever weight we are, fat or thin. One of the worlds leading obesity researchers, geneticist Professor Stephen ORahilly, goes so far as to say we are on the threshold of a complete change in the way we view not only morbid obesity, but also everyday overweight. Prof. ORahillys groundbreaking work in Cambridge has proven that obesity can be caused by our genes. These people are not weak-willed, slothful or lazy, says Prof. ORahilly, They have a medical condition due to a genetic defect and that causes them to be obese.
