The science isn’t conclusive regarding whether or not intermittent fasting boosts testosterone in men. Some studies show that testosterone levels are raised when men first start fasting, but as time goes on, testosterone levels drop.

Intermittent fasting has numerous health benefits and can increase your vitality and energy levels. You will look and feel better and probably be more attractive to others.

Your improved health will give you increased strength and can improve your sex drive, but it might not be due to increased testosterone levels. Your overall health will help you get benefits usually associated with increases in testosterone.

Key Takeaways

  • The science on whether or not intermittent fasting boosts testosterone in men is inconclusive. While some studies show a temporary increase in testosterone levels, it is unclear whether this effect is sustained over time.
  • Intermittent fasting has numerous health benefits beyond boosting testosterone levels. It can improve overall health, increase energy levels, and reduce the risk of diseases like diabetes, Alzheimer’s, and cancer.
  • While intermittent fasting may not be suitable for everyone, there are other ways to boost testosterone levels, such as improving your diet, lifting weights, reducing stress, and getting enough sleep and vitamin D. Heavy alcohol consumption and other harmful environmental factors can negatively affect testosterone levels.

Testosterone and Fasting

What is known about intermittent fasting is that it increases HGH (human growth hormone) and the testosterone precursor LH (luteinizing hormone).

Intermittent fasting normalizes and regulates hormone levels regarding insulin and anti-aging hormones. More studies need to be done to determine the effects of intermittent fasting on men of different body types.

Fasting affects the endocrine system, which controls all types of hormones in your body. It can help reset hormone levels and normalize them. Whether or not certain hormone levels increase or decrease after intermittent fasting often depends on where you start in your fasting journey.

Choose Intermittent Fasting for Improved Health

Intermittent fasting is more than just an excellent way to lose weight. Intermittent fasting has anti-aging benefits and can reduce your risk for diabetes, Alzheimer’s, and cancer.

However, intermittent fasting isn’t for everyone. For people underweight or trying to build muscle mass, intermittent fasting doesn’t provide enough calories. The same goes for pregnant and nursing women.

People with eating disorders are at risk, and intermittent fasting isn’t recommended. If you have any health conditions or are on medication for heart problems, consult your doctor before starting a fasting plan.

Use Diet and Exercise to Boost Testosterone

Even without intermittent fasting, improving your diet will boost your testosterone levels. Good nutrition can normalize your hormone levels, and eating a diet with adequate protein, carbs, and fat will help you maintain healthy levels of testosterone.

Lifting weights and exercising can also increase your testosterone levels. Even though any type of exercise will help improve your testosterone levels, high-intensity, and resistance training are the most effective short-term methods of boosting testosterone.

Other Ways to Boost Testosterone

Stress is extremely hard on your body and reduces your testosterone levels. Stress can also cause you to gain weight and lose sleep, which is also hard on your hormone balance.

Get plenty of sleep and maintain a healthy body. If you continue to be stressed, try practicing meditation or yoga.

Fresh air and sunshine can help you boost your Vitamin D levels, which is also associated with increases in testosterone. If you cannot get adequate sunlight, take a Vitamin D supplement or multivitamin.

Heavy alcohol consumption also negatively affects your testosterone levels. Changes in your testosterone levels happen quickly after alcohol consumption. In just 30 minutes after consuming alcohol, your testosterone levels drop. Heavy drinking and other harmful environmental factors can cause drops in testosterone levels.

Choosing the Right Fasting Method

You might have to play around with fasting methods before you find the one that works best for you. Start slow, ask other people for help, and stay hydrated.

No matter what type of fasting technique you choose, it can be tough to stay on track, and using a fasting app will help you improve your chances of success.

Fasting apps are easy to use and do more than just tell you when your eating and fasting windows stop and start. A good fasting app will prompt you to keep track of your meals, track your moods, and document your physical activity.
