Obesity and diabetes: The link is not as clear as you might think

We keep hearing about the epidemics of type 2 diabetes and obesity. There is also a tendency to link the two. Certainly, obesity is a risk factor for type 2, but the link is nowhere near as straightforward as you might think.

My latest HND piece takes a hard look at this, and reports a few interesting things...

  • People afflicted with Berardinelli-Seip syndrome have virtually no body fat, yet ALL of them are diabetic.

There is also a big glitch in the classical "thrifty gene" explanation of how the Pima Indians became diabetic, once they moved from Mexico to Arizona.

In short, beware of simple explanations, when applied to something as incredibly complex as human metabolism.
