Biggest Loser proves genes don't control weight, says Michelle Bridges.
From Sunday Life
I am not a scientist. However, I can't help being fascinated by what is going on in the research world as it relates to obesity and weight management. One of the things scientists are focusing their attention on is the field of epigenetics, which explores how every gene a person has inherited ends up expressing itself in their physical and neurological characteristics. This subject is even more interesting now that science has unravelled the human genome sequence.
In the past, we've looked to our parents and grandparents for the determinants of the way we look, or for our propensity for disease or obesity. What epigenetic research tells us is that our genes themselves are not wholly responsible for our physical characteristics.
