New York: For many men suffering from testosterone deficiency, losing weight can help increase testosterone levels. Researchers say that a particularly low-fat diet may be associated with a small but significant decrease in testosterone. "We found that men who followed a fat-restrictive diet had lower serum testosterone than men who did not follow a restrictive diet," said researcher Jake Funtas of the University of Chicago, US.
"Although the clinical significance of small differences in serum-T in the diet is unclear," Funtas said.
The research team analyzed data from more than 3,100 men from a nationwide health study (National Health and Nutrition Examination Survey, or NHANES) for the study published in the Journal of Urology.
All participants had data on diet and serum testosterone levels.
The American Heart Association (AHA) defined that 14.6 percent of men met the criteria for a low-fat diet based on a two-day diet.
On the other hand, 24.4 percent of the men consumed diet like fruits, vegetables and whole grains. These people reduced the intake of protein and dairy products from animals.
Only a few men involved in the research took a low carbohydrate diet with AHA criteria, so this group was excluded from the analysis.
Average serum testosterone levels in men during research were 435.5 ng / dl (nanograms per dl).
According to the study, men taking a restrictive diet found less serum testosterone, which was found to be 411 ng / dL on a low-fat diet.
Testosterone is a hormone found in men in their testes. It increases sexual power within men and maintains adequate levels of muscle and red blood cells and is also helpful for sexual functions.
