Fidgeters 'Likely To Be Thinner'

Scientists working in Germany and the US say they have found a "fidget" molecule and if you have it in your genes you are less likely to be fat.

Mice with the molecule are more likely to be primed athletic beasts, while those without laze around getting fat.

It is the second time in recent months scientists have claimed to have located genetic material linked to body weight.

Scientists in Britain said they had found a separate gene, dubbed the fat gene, linked directly to obesity.
