Men with beer bellies warned they are at risk of weaker bones

Men with excessive fat around their middles aren't just putting their hearts under strain - they are also at risk of weaker bones.

A study from Harvard Medical School found men with beer bellies had a higher chance of developing osteoporosis, a disease usually associated with older women.

The condition makes bones more prone to breaks as they lose density. Over a third of women have one or more bone fractures because of osteoporosis in their lifetime, however so do one in five men.

'Most studies on osteoporosis have focused on women,' study leader Dr Miriam Bredella said. 'Men were thought to be relatively protected against bone loss, especially obese men.

' To check this assumption, Dr Bredella and her team of researchers evaluated 35 obese men with a mean age of 34 and a mean body mass index, a measure of body fat, of 36.5.


The men were divided into two groups: one with mainly subcutaneous fat, which lies just beneath the skin and is spread all over the body, and the other with mostly visceral or intra-abdominal fat, located deep under the muscle tissue in the abdominal cavity.

 Visceral fat, which is what causes the a pot belly even in thin people, is far more menacing because the fat is packed in-between the inner organs and is strongly linked to heart disease. Genetics, a high-fat diet and a sedentary lifestyle all contribute to visceral fat.

 'What surprised us most was that men with visceral fat had significantly weaker bones than (the subcutaneous fat) group. These are men with the same degree of obesity and who were about the same age,' Dr Bredella said.

 For the study, she put the men through a computed tomography, or CT scan, of the abdomen and thigh to measure fat and muscle mass, as well as very high resolution CT of the forearm. She assessed bone strength to predict fracture risk using a technique called finite element analysis, which is used in mechanical engineering to determine the strength of materials for the design of bridges and airplanes.
