Does Intermittent Fasting Increase Testosterone?

Intermittent fasting concept, empty plate and full plate

Studies show that men of this generation have declining testosterone levels compared to those of the previous generation. According to the 2007 study, an ordinary 65-year-old man in 2004 had 17% lower testosterone than a typical 65-year-old man in 1987. Another alarming fact is that around 40% of 45-year old men have hypogonadism.

The increasing health concerns regarding lower testosterone levels are raising awareness about methods to increase testosterone. One of the methods being considered effective in increasing testosterone levels is intermittent fasting. The question is: does intermittent fasting increase testosterone?

Intermittent Fasting and Testosterone

Intermittent fasting is one of the most celebrated trends worldwide. There is a link suggested between testosterone levels and intermittent fasting. Let's discuss the practice of intermittent fasting and its possible effects on testosterone.

What is Intermittent Fasting?

Intermittent fasting involves restricting energy consumption for specific periods, so you have periods of normal food consumption paired with periods of fasting. There are several methods for intermittent fasting that can differ in the fasting periods and how intense they should be.

The practice is gaining popularity due to its links with several health benefits. It has proven results for people trying to lose weight, and it can even help improve cognitive function in people, based on observations so far.

Does Intermittent Fasting Improve Testosterone Levels?

There needs to be more extensive research into the benefits of intermittent fasting. When it comes to intermittent fasting and testosterone, there is still a lot of debate. There are studies suggesting that fasting has an impact on the process that encourages testosterone production. However, there is no consensus on whether it is always effective.

An early study from November 1989 suggests that intermittent fasting can boost testosterone levels. The study observed nine obese and eight healthy men to study how intermittent fasting affects the luteinizing hormone (LH). The hormone is important for healthy testicular function and production of testosterone.

The study found negligible effects on obese men. However, the non-obese men observed a 67% increase in LH levels. The result was a 180% boost of testosterone in the non-obese men. The result showed a marked difference in testosterone levels due to intermittent fasting. However, such a small pool of people cannot count as a very reliable study.

Some studies have found completely opposite results of intermittent fasting and testosterone levels. A recent study of energy restriction showed a decrease in testosterone levels in the subjects.

Final Thoughts: Does Intermittent Fasting Increase Testosterone?

Despite a very promising result from an old study, the scientific community still has a long time to go before it can adequately determine whether intermittent fasting increases testosterone levels.

There is a chance that intermittent fasting can help through other health benefits linked with the practice. However, relying on the practice to boost testosterone might not be the best possible way to go. There are other natural ways you can increase testosterone levels. If you are experiencing low testosterone levels, you should consult with a doctor to determine the best possible course of increasing your testosterone to healthier amounts.
