Well done hevab. The waist measurement is because a larger waist increases our resistance to insulin. Over 37 for a man is given as a sign of insulin resistance. Not sure of the figure for a woman. But a large waist means bigger fat cells which makes it harder for our insulin to put excess sugars from our blood into those cells. I think the actual measurements are a bit of a stab in the dark, because 37inches for me at 6ft 1in is not as bad as 37 inches for a bloke who's 5ft and a fag paper tall. But the idea is right.
