Can fasting boost testosterone?

Intermittent fasting can potentially increase testosterone by 180%. It does this by triggering the hypothalamus and releasing GRH.  Insulin will kill your testosterone levels. 

Things that increase insulin:

• Eating 

• Frequent eating 

• Carbs 

• Alcohol

• Being fat

As you lose weight, it will likely get easier and easier to stimulate testosterone. Consider fasting for at least 16 hours with an 8-hour eating window. It may be beneficial to work up to 20 hours of fasting with a 4-hour window of eating.
