3、ore than half the Australian population(63% of men and 47% of women)to a life of battling with their weight The argument goes like this: it doesnt matter how little they eat， they gain weight because their bodies break down food and turn it into energy more slowly than those with a so-called normal

4、metabolic rate 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 cl

5、ear, 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 lifeti

6、me: 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

7、 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 leadinq obesity researchers, geneticist Professor Stephen ORahilly, goes so far as to say we are on the threshold of a com

8、plete change in the way we view not only morbid obesity, but also everyday overweight. Prof. ORahilly s 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. O Rahilly, They have a medical condition due to

9、a genetic defect and that causes them to be obese. E In Australia， the University of Sydneys Professor lan Caterson says while major genetic defects may be rare， many people probably have minor genetic variations that combine to dictate weight and are responsible for things such as how much we eat，

10、the amount of exercise we do and the amount of energy we need When you add up all these little variations, the result is that some people are genetically predisposed to putting on weight He says while the fast/slow metabolism debate may have been settled that doesnt mean some other subtle change in

11、the metabolism gene wont be found in overweight people He is confident that science will， eventually, be able to cure some forms of obesity but the only effective way for the vast majority of overweight and obese people to lose weight is a change of diet and an increase in exercise F Despite the $50

12、0 million a year Australians spend trying to lose weight and the $830 million it costs the community in health care Obesity is at epidemic proportions here, as it is in all Western nations Until recently, research and treatment for obesity had concentrated or behaviour modification， drugs to decreas

14、ng other things But it wasnt until 1994 that Professor Jeffery Friedman from Rockerfeller University in the US sent science in a new direction by studying an obese mouse Prof Friedman found that unlike its thin brothers， the fat mouse did not produce a hitherto unknown hormone called leptin Manufact

15、ured by the fat cells， leptin acts as a messenger, sending signals to the hypothalamus to turn off the appetite Previously, the fat cells were thought to be responsible simply for storing fat Prof Friedman gave the fat mouse leptin and it lost 30% of its body weight in two weeks H On the other side

16、of the Atlantic Prof ORahilly read about this research with great excitement For many months two blood samples had lain in the bottom of his freezer, taken from two extremely obese young cousins He hired a doctor to develop a test for leptin in human blood， which eventually resulted in the discovery

17、 that neither of the childrens blood contained the hormone When one cousin was given leptin she lost a stone in weight and Prof ORahiIly made medical history Here was the first proof that a genetic defect could cause obesity in humans But leptin deficiency turned out to be an extremely rare conditio
