Testosterone impacts numerous aspects of health. Testosterone levels typically peak during adolescence and early adulthood, then naturally decline with age. It’s involved in muscle growth, bone density, and mood regulation, among other functions. This powerful hormone drives many essential bodily processes. You’ve probably heard of it, the celebrated hormone.

Specializing in Performance Psychology, his expertise is backed by both rigorous study and practical experience. While fasting may increase total testosterone, the increase is often overshadowed by the rise in SHBG levels, reducing the bioavailability of free testosterone. For men seeking ways to optimise hormone levels or improve overall health, fasting could be a valuable tool when used correctly. While intermittent fasting for hormone health shows promise, it’s not suitable for everyone. One study that is often cited to support the idea that fasting boosts testosterone is from 1989. Unfortunately, the research into the link between intermittent fasting and testosterone has not yet revealed a clear picture. It is thought that intermittent fasting has a number of health benefits. It is secreted from the fat cells in the stomach to send signals to the brain that food consumption is no longer necessary. Leptin, sometimes referred to as the satiety hormone, is largely responsible for making you feel full after meals. So, for example, you may choose Wednesday and Friday as your one-meal days and continue to eat normally every other day for the rest of the week. In general, the beneficial effects of mineral water consumption on changes in blood pressure 27,28, plasma lipid profile 29,30, propensity to lower insulin levels in blood after meal 30,31 and prevention of undesirable weight gain has been documented. It should be noted that disturbances in the fluid and electrolyte balance may have serious consequences for the proper functioning of the body and may also accompany the water-only fasting. The most extreme fasting, which is also practiced in some religions, is based on periodic starvation for several days or longer and water-only fasting, which is defined as the total abstinence of food except for water. Moderate energy restriction which characterizes the intermittent fasting has been shown to extend the span life of laboratory animals 3,4. The results showed that after 8 days of water-only fasting, Qmax and IPSS improved but PV and TTV decreased significantly. Yes, consulting a healthcare provider is recommended to assess individual health risks before starting any fasting regimen.
