that's part of the problem, with male BMI I'm underweight, but with female weight I'm in the ideal range. I also fail to see why men and women have different dietary needs, and I suspect it's men's diets that are causing the male gender to die soon than women. Women generally take better care of their body not only through diet but are far more willing to see a doctor them men generally are I think men could learn alot from women in this respect.
