Exercise instantly boosts fat-busting genes

Now there is no excuse to avoid the gym: just one hour of exercise instantly changes your genes to boost the breakdown of fat.

Scientists looked for epigenetic changes – the addition of a methyl group to genes – in muscle cells during strenuous exercise. To do so, the team collected biopsies from the thigh muscles of eight men who led relatively sedentary lives, both before and after an hour of exercise.

Several genes involved in fat metabolism that were methylated before the exercise lost their methyl group. Such demethylation allows genes to more easily make proteins, which suggests that more proteins involved in the breakdown of fat are being made after exercise. Learn more here or here.
