A low-calorie ketogenic diet can increase testosterone levels in obese men

New research shows that a low-calorie ketogenic diet can improve testosterone levels in overweight men and reduce obesity overall.

A very low-calorie ketogenic diet can improve testosterone and sex hormone (SHBG) levels in overweight men. This is the result of a study that was presented at the 23rd European Congress of Endocrinology (e-ECE 2021) on Monday, May 24th, 2021, at 2 p.m.: 06:00 CET.

The study found that following a recommended low-calorie ketogenic diet for four weeks, body weight, fat mass, and body mass index (BMI) decreased significantly, and there was also a significant increase in total testosterone and SHBG levels. Testosterone is responsible for sexual and reproductive functions. However, it also plays an important role in calorie utilization and metabolism.

This study was the first of its kind to examine the effects of a very low-calorie ketogenic diet on testosterone and SHBG levels, highlighting the close relationship between insulin effects, energy balance, and testicular function. Because men who are overweight or obese may also suffer from low testosterone and SHBG levels, the data suggests that further research on a low-calorie ketogenic diet and its effects on male testosterone and SHBG levels is a promising area for additional Could be research.

The global obesity prevalence nearly doubled between 1980 and 2008. The country estimated for 2008 that over 50% of men in the WHO European Region were overweight and around 20% were obese. Obesity can lead to diabetes and heart disease, as well as mental health problems.

To address this problem, various lifestyle changes, activities, and treatments are widely recommended, and a ketogenic diet is increasingly recognized as one of them. The diet is low in protein and very low in carbohydrates, and when performed very low in calories, a daily intake of less than 800 calories is recommended. A very low-calorie ketogenic diet was previously found to reduce body weight, glycemia, and insulinemia, but its effects on total testosterone and SHBG levels have so far been less clear.

Dr. Angelo Cignarelli and a team of colleagues from the University of Bari in Italy investigated whether this controlled diet would have the same positive effect that it had on total body weight for total testosterone and SHBG levels. The 17 male subjects in the study were on a low-calorie ketogenic diet for four weeks, and various tests were performed before and after one (1) and four (4) weeks.

We wanted to assess the response of total testosterone and sex hormone levels to a very low calorie ketogenic diet in a cohort of overweight or obese non-diabetic male subjects. We found that there is a discernible relationship between a certain controlled diet and insulin action, energy balance and testicular function. “

This is the first study to examine the early response of androgen levels to the introduction of a very low-calorie ketogenic diet, highlighting the relationship between insulin action, energy balance, and testicular function.

The results of this study now show that a very low-calorie ketogenic diet can have a positive effect on total testosterone and SHBG levels. Further analysis will provide information on the impact of this nutritional intervention on additional clinical outcomes related to testosterone such as sexual function, muscle strength and quality of life.
