The fat gene mystery

That genetic differences are responsible for weight gain has long been thought by scientists. Indeed those suffering from excess weight are also sometimes keen to suggest this too. There maybe something to this though as slight differences in a single gene could be responsible for suppressing metabolism, thus making those individuals tired and unable to burn calories effectively.

Scientists now believe that the gene may control the rate of metabolism. This could well explain why some individuals find it more difficult to lose or to gain weight. With more testing scientists hope to develop drugs that will modulate the genes activity, but Dr Ruther suggests that the gene "have more complex effects on both food intake and energy expenditure than has been so far".
