A study on how men with higher body fat are at an increased risk of osteoporosis was published in the Endocrine Society's 'Journal of Clinical Endocrinology and Metabolism'. Most studies have shown positive or neutral effects of body fat mass -- the weight of fat in your body -- on bone health. Lean mass is the entire weight of your body, including organs, skin and bones, minus the fat. Health care providers often assume people with higher body weight have high bone density and are at low risk of fracture, and these patients are less likely to be screened for osteoporosis.
"We found that higher fat mass was related to lower bone density, and these trends were stronger in men than women," said Rajesh K Jain, MD, the University of Chicago Medicine in Chicago, Illinois. "Our research suggests that the effect of body weight depends on a person's makeup of lean and fat mass and that high body weight alone is not a guarantee against osteoporosis."
