Welcome to my website! I’m Ryan Fernando, a nutrition coach, and today, I’m addressing a question that many people have been curious about:
Can fasting increase your testosterone levels?
This question is surrounded by a lot of confusion, especially with so many claims circulating on social media about fasting increasing testosterone by thousands of percent.
Some say it’s a 13,000% increase, while others talk about 1300%, or even just a 13% boost. Terms like “natural testosterone storage” are thrown around too. So, what’s the truth? Is fasting really the magic solution for boosting testosterone, or is it based on incomplete research and misunderstandings?
Let’s dive in and break it down step by step to understand whether fasting can really help or not.
What Is Testosterone?
First things first, let’s talk about what testosterone actually is. Testosterone is a hormone found in both men and women, but it’s more prominent in men. It’s essential for energy, muscle development, and mood regulation. In men, it also plays a crucial role in the development of male characteristics, such as a deeper voice and facial hair.
To simplify, think of testosterone as a coach who helps your body perform better, with muscles being the players. If the coach (testosterone) is active, the players (muscles) perform better.
Now, what’s important to note is that testosterone doesn’t get stored in your body like fat or sugar. It exists in two forms in the blood: free testosterone and bound testosterone. Free testosterone is the active form that your body can use, while bound testosterone is attached to a protein called SHBG (Sex Hormone Binding Globulin). When SHBG levels are high, more testosterone gets bound and is unavailable for use, leading to a decrease in free testosterone. This can lead to symptoms like fatigue, low muscle strength, and reduced libido.
On the other hand, when SHBG levels are low, less testosterone gets bound, allowing more free testosterone to circulate in the body. However, even this situation can create problems like acne, hormonal imbalances, and other health issues.

Fasting and Testosterone: What Does the Research Say?
Now, let’s get into the real question: Can fasting increase your testosterone?
When I looked into the research, I found that fasting does not significantly increase testosterone levels. In fact, studies suggest that fasting may actually lead to an increase in SHBG levels, which means that free testosterone levels might decrease as a result. This contradicts the popular claim that fasting boosts testosterone significantly.
While fasting may increase total testosterone, the increase is often overshadowed by the rise in SHBG levels, reducing the bioavailability of free testosterone. The body may have more testosterone circulating, but it won’t be able to use it effectively. This can lead to symptoms like fatigue and low libido, making fasting less effective for boosting testosterone than people believe.
Growth Hormone and Fasting
Fasting can also increase growth hormone levels, which plays a role in repairing and building muscle. However, this effect is often not as significant as many might think. Growth hormone increases because the body starts breaking down fat for energy during fasting. This process, known as lipolysis, helps the body use stored fat for fuel.
But just like testosterone, the impact of fasting on growth hormone is not as dramatic or consistent as some claims suggest.
Inflammation and Fasting
One of the more subtle benefits of fasting is its impact on inflammation. Inflammation is your body’s natural response to injury or infection, like a fire alarm signaling that something is wrong. While this alarm can be helpful, excessive or chronic inflammation can cause problems.
Research shows that systemic inflammation (the kind that shows up in blood tests) is often higher in people with excess body fat. Fat cells release certain chemicals called adipokines that increase inflammation. However, when fat is reduced through fasting or calorie control, inflammation tends to decrease.
Interestingly, studies have not shown that fasting is significantly more effective than calorie restriction for reducing inflammation. In fact, fasting alone isn’t the ultimate solution; the key to reducing inflammation is overall fat loss and better metabolic health, which can be achieved through a variety of methods, not just fasting.
Autophagy and Fasting
Another concept often associated with fasting is autophagy. Autophagy is your body’s natural process of cleaning out damaged cells and regenerating new ones. It’s like an internal cleanup crew. Fasting has been shown to activate autophagy, but it’s not unique to fasting. Even regular calorie restriction can stimulate autophagy.
The idea that fasting is the only way to achieve autophagy is misleading. Whether you fast or follow a calorie-controlled diet, autophagy can still be triggered.
Should You Fast?
So, should you fast or not? My simple answer is: If fasting suits your body and health goals, then go for it.
However, there are a few things to keep in mind. Fasting for more than 24 hours is generally not recommended unless advised by a medical professional. Intermittent fasting, which involves having a 12 to 14-hour gap between your last meal of the day and your first meal of the next day, can be effective for weight loss and metabolic health. A once-a-week light fast or a water fast can help detoxify the body. Religious fasting can be beneficial too, as long as your body is ready for it and there are no health concerns.
Fasting without planning, or following trends blindly, is not the way to go. Understand your body’s needs and adapt your approach accordingly. It’s essential to have a therapeutic and nutrition-based approach tailored to your body’s requirements.

To sum up, fasting can be a helpful tool for maintaining metabolic health, fat utilization, and body weight. However, fasting isn’t the magic solution for boosting testosterone. It’s essential to understand that every body is unique. What works for one person may not work for another. Before you jump on any health trend or follow claims without scientific backing, make sure you understand the science behind it.
Finally, always start with a proper body diagnosis to understand your health goals and needs. Whether you’re looking to lose weight, gain weight, or address specific health issues, your approach should be personalized. This is what we call bio- individuality – what works for one person may not work for another.
