Why do older men with low testosterone often have belly fat and heart risks?
Low total testosterone levels are associated with the metabolic syndrome in elderly men: the role of body weight, lipids, insulin resistance, and inflammation; the Ikaria study.

Older men with low testosterone tend to have more belly fat, high blood sugar, and inflammation — all signs of metabolic syndrome. But when scientists looked closer, they found testosterone itself might not be the cause — it’s more about weight, insulin, and inflammation.
Surprising Findings
The 3% reduced MetS risk per 10 ng/dL testosterone increase disappeared entirely after adjusting for BMI, insulin, lipids, and hs-CRP.
Most media and supplement companies claim testosterone directly improves metabolism—this study shows the association is entirely mediated by obesity and inflammation.
Practical Takeaways
If you're an older man with low testosterone, focus on losing belly fat, improving insulin sensitivity (via diet/exercise), and reducing inflammation before considering hormone therapy.

In men 75 and older, having more testosterone in the blood is linked to a lower chance of having metabolic syndrome — for every little boost of 10 ng/dL in testosterone, their risk drops by about 3%, no matter how much they sleep, exercise, or eat.
When men have very low testosterone for a long time, it can mess up their metabolism and make their body and mind not work as well as they should.
In older men, having less testosterone seems to go hand-in-hand with having a bigger waist, higher blood sugar, more body inflammation, and lower 'good' cholesterol — all signs of metabolic syndrome — but this doesn’t happen the same way in older women.
In older men, low testosterone doesn’t seem to directly cause metabolic syndrome—instead, it’s mostly because they tend to have more body fat, insulin problems, inflammation, and bad cholesterol, which are the real culprits.
In older men, having low testosterone seems to go hand-in-hand with more heart disease, but that’s probably because low testosterone often comes with other issues like being overweight, having high blood sugar, or inflammation — so it’s not necessarily testosterone itself causing the problem.
