Fasting has been around for a very long time. Before the conveniences of agriculture and social structure, ancient peoples had to hunt and gather. This meant it was possible to have days go by in between meals.
Our bodies are naturally adapted to fasting but with a constant flow of calories at our fingertips, many people have forgotten about this natural instinct. Fasting is a making a strong comeback as a way to increase testosterone and overall health.
What is Intermittent Fasting?
Intermittent fasting is a unique way of timing your meals so that you are only eating for eight hours per day. A 16-hour fast may sound brutal but most of it takes place during the hours when you’re sleeping.
Intermittent Fasting Benefits
While it may take some time to adjust, intermittent fasting has been scientifically shown to promote a variety of health benefits:
- Increased weight loss
- Improved body composition
- Promotes brain cell growth and overall brain health
- Supports anti-aging benefits through cell protection
- Triggers the production of recovery-focused growth hormones
Intermittent Fasting and Testosterone Levels
Intermittent fasting has also been shown in several studies to trigger the production and release of testosterone in the body. One study showed that men fasting during Ramadan experienced a significant increase in testosterone levels during this period.
How to Use Intermittent Fasting
When using intermittent fasting to increase testosterone levels, you will fast (eat nothing) for 16 hours. During this time, you can still drink plenty of water, plain tea, black coffee, and calorie-free beverages. You will then have an eight-hour window to eat your normal diet. Most people will begin fasting at 8 p.m. and then eat their first meal at 12 p.m. the following day.
