More blogging on Fit/Fat Times blog

To Sharon X; post #115 - Sharon said: "Dr. Abby A. wrote: “BMI discriminates against women, since we are genetically programmed to store more fat in hips breasts and thighs, yet are held to the same BMI standards as men.” This statement is illogical because men almost always carry more lean muscle than women (testosterone vs. estrogen) at the same weight, so the man at 5Åå9Åç
and 180-lbs is automatically going to be leaner than a women at that height and weight. Muscle weighs more than fat."

Great Point, Sharon X! After thinking about it, it seemed that you were right, so I bounced it off a highly credible and influential researcher, Paul Ernsberger, Ph.D. He wrote back to say, " She’s right in so far as, for a given BMI, a woman will have a higher % body fat. This is only important if you believe that % body fat is important, which I do not."

I wrote back and said, "Paul, am I correct in assuming that even though a woman probably has a higher body fat at any given BMI, it's irrelevant because it has nothing to do with fitness, as measured by endurance and/or strength?"

He wrote back and said "yes." So I thank you again for making me think, and for helping us towards a greater understanding of these issues.
