Fat & happy

November 23, 2012

Canadian scientists have found proof for the adage fat and happy:

. . . Scientists out of McMaster University have discovered a happy gene — and it just so happens to be the same one that is a major contributor to obesity.

“So you can be obese, and happy,” said David Meyre, an associate professor at McMaster’s department of clinical epidemiology and biostatistics and a senior author of the study released Tuesday in the journal Molecular Psychiatry.

“This is the first time we know there is some biological reason, or a pathology, behind something like mental health, especially depression,” added first author Zena Samaan, an assistant professor at McMaster’s department of psychiatry and behavioural neurosciences.

The scientists set out to find out which genes leave people more susceptible to depression. What they found was that a gene that predisposes some people to obesity, called FTO, also offers some protection against depression. . .

If the happy gene is a  fat one, does the reverse apply making the miserable gene a skinny one?
