Comment of the Week

We are lucky enough to have La Wade, a real live scientist, saying smartypants things in the comments.

"You're right that being fat doesn't cause diabetes, but a lot of the physiological changes associated with being fat do. Fat tissue secretes a number of hormones that are important for regulation of glucose homeostasis, especially PPAR-gamma and leptin. The more fat tissue you have, the harder it is for your body to correctly regulate levels of these hormones. In addition, many overweight and obese people become so through poor diet, overeating, and lack of exercise, all of which can contribute to diabetes. You are not guaranteed to become diabetic if you're obese, but it dramatically increases your risk."
