Losing Weight can improve Low Testosterone Levels in Men

Weighing in - BSN

(Best Syndication News) - A study found that overweight men could improve their low testosterone levels by losing extra weight and exercising more. The men in the study were middle age, overweight, and had pre-diabetes. The results were presented this week at The Endrocrine Society’s 94th Annual Meeting in Houston, Texas.

Study co-author Frances Hayes, MD, professor at St. Vincent's University Hospital, Dublin, said that doctors should try to support men in their efforts to lose weight before prescribing testosterone therapy to restore low levels of the hormone.

Around 900 men that had impaired glucose tolerance, or pre-diabetes, were participants in the Diabetes Prevention Program. The study participants helped to first determine that weight loss can help delay or avoid developing type 2 diabetes. Now, the same participants were used to learn more about testosterone levels and weight loss.

The researchers narrowed their study down to 891 participants because they ruled out men that were diagnosed with hypogonadism and were already taking hormone therapy to restore testosterone levels. The remaining participants were randomly assigned to one of three treatment options. Lifestyle modification was assigned to 293 men. The second group consisted of 305 men who were assigned to take the diabetes drug metformin. The remaining 293 participants were given a placebo medication.

The lifestyle modification group were tasked with the job of exercising 150 minutes each week along with reducing dietary fat and eating less calories overall.

At the beginning of the study, around one in four men showed low testosterone levels under 300 nanograms per deciliter. After one year, the lifestyle modification group showed improvements. This group started at around 20 percent of the men having low testosterone levels, and by the end of a year, the rate was 11 percent. The metformin group started at 24.8 percent and ended at 23.8 percent at the end of the year. The placebo group at the start was 25.6 percent and at the end, it was 24.6 percent.

The lifestyle modification group also lost on average 17 pounds over the course of one year.
