If female and your waist/hip ratio is above .8 you are said to be at increased risk for coronary disease than if you are less than that. I found my tape measure and took my measurements. My waist is 28 inches. My hips are only 34 inches. This puts me at .82, at increased risk for coronary disease. I am 5'5'' and weigh 115 pounds. My arms and legs are virtually fat free and look like tooth picks and my hips are pretty fat free too. Several of my bones stick out.
When I was heavier, my waist was only a little bigger and I had more weight on my hips and was below .8. In fact the heavier I was (i got up to 150 at one time), the lower my waist/hip ratio. Was I really at a lower coronary disease risk when I was overweight than I am now underweight?
