Insulin resistance develops diabetes, and leptin resistance develops obesity. You'll see girls with muffin tops and saddle bags. Then there's the pregnant man look - you know that solid looking potbelly. That's visceral fat, fat surrounding the organs of the abdomen. Yuck!
And to tie everything together, elevated blood sugar levels for long periods of time corrode the arteries; cholesterol (which is actually a friend to the body) comes in and patches up the "rust spots" in the blood vessels. The excess sugar travelling around in your blood stream from the inability of insulin to deliver causes heart disease in that sugar acts as rust on our blood vessels.
