I find it laughable that people worry their testosterone levels will decrease when they go without food for more than 3 hours, when it’s widely known that testosterone levels are at their highest early in the morning, just after an overnight fast (the very reason why you get morning wood!).
Though it’s true that longer fasts lasting several days can lead to a slight decrease in testosterone levels, there is no evidence to suggest this happens during intermittent fasts of 16-24 hour duration.
Here are 3 ways that I think intermittent fasting can actually BOOST testosterone in your body:
1. Reduces Generalized Body Fat
Research presented at the Endocrine Society’s 2012 meeting indicates that overweight men across the board, have drastically lower levels of testosterone. This is because fat cells contain the enzyme aromatase, which converts testosterone to estrogen. Fat cells also store estrogen.
The influence of fat cells in keeping testosterone levels low is so strong that REDUCING body fat is easily one of the most effective ways to boost testosterone.
Since studies have found that intermittent fasting is more effective than traditional diets at reducing body fat, this means that intermittent fasting also plays an important role in reducing testosterone.
2. Enhances Insulin Sensitivity
A 2005 study in The Journal of Clinical Endocrinology & Metabolism found that insulin resistance actually directly inhibits the Leydig cells in your testes from producing testosterone.
When you enhance insulin sensitivity, you reduce insulin resistance, thereby allowing your Leydig cells to produce more testosterone.
3. Prevents Feeding-Induced Testosterone Reduction
Studies have shown that even a small meal (about 300 Calories) is able to decrease serum testosterone levels for over 3 hours, and it doesn't seem to matter whether this meal is made of Fat, Protein, Carbohydrates or sugars.
So imagine having 6 meals a day where you eat every 3 hours. That would mean your testosterone levels stay low ALL DAY! As opposed to the fasted state, where your T levels remain high and unchanged throughout the fast.

The trouble with intermittent fasting is you have to know how to do it right. Did you know for example that a lot of Muslims who fast during Ramadan either don't lose any weight, or even end up GAINING weight in the process?
The fact is, that there are some methods of intermittent fasting that almost guarantee failure, while there are other methods that almost guarantee success. I see a lot of newbies to intermittent fasting commonly making the same mistakes over and over again.
To find out what these mistakes are, and ensure that YOU start out with a method of intermittent fasting that can guarantee SUCCESS, grab yourself a copy of my new book, Untold Secrets of Intermittent Fasting. You can get it here:
