The Nature Genetics Journal reporting that the “lean gene” not only keeps people skinny but causes type 2 diabetes.

Conventional thinking by health officials is that obese (fat) and sedentary (lazy) people are the most at risk for type 2 diabetes (despite the fact that the majority of diabetics live in China and India, where there isn’t that many fat or lazy people).

A study of the IRS1 gene revealed that not only does it keep people skinny by burning up fat, but it also increases heart disease and type 2 diabetes by 20%.  Scientists weren’t expecting that result.  The study proves that just because you’re naturally skinny doesn’t mean you’re healthy.
