Canadian scientists prove link between the gene that causes obesity and rates of depression

The old saying 'fat people are more jolly' has more than a grain of truth to it. It turns out there's good reason for the stereotypical "happy" fat person immortalised in characters like Santa Claus - it's genetic.

Scientists from McMaster University in Canada have found that the so-called 'fat gene' FTO is also responsible for people's sense of wellbeing or happiness.

FTO is a genetic contributor to obesity but it also reduces the risk of depression by up to eight per cent.

The scientists studied 17, 200 DNA samples in a study investigating the psychiatric health of a group of people from over 21 nations. The finding that FTO lead to a lower rate of depression was backed up by three further international studies.

While eight per cent might not sound significant, Professor David Meyre, of McMaster University in Canada, said that it was the "first evidence that an FTO obesity gene is associated with protection against major depression, independent of its effect on body mass index."

He said the discovery won't change the day-to-day treatment of patients, it identifies a "a novel molecular basis for depression."

    There's probably a link to comfort eating which is over eating to lift the mood. Both weight and mood are elevated linking unhealthy obesity with happiness.

    It's true what they say.You are what you eat.Why is it so hard for people to understand what a healthy weight is.Healthy weight is not under or over weight.There are other ways to reduce depression,for example exercise,meditation the list goes on.If your stomach is empty then your life becomes empty too.

    I found early in life that when you try to share in their jolliness they often turn into being plain rude and obnoxious.
