Intermittent fasting increases testosterone in older males?
In response to our email about Bill Faloon's recent blood test results, we've had more than one male supporter tell us they've seen their testosterone levels increase while regularly practicing intermittent fasting.
To further substantiate that observation, Paul McGlothlin, President of The CR Way Longevity Center, sent Bill Faloon the following message about this phenomenon, which he has observed in his community. He allowed us to share this message on the forum here:
Happy New Year, Bill.
Both Intermittent fasting and calorie restriction can raise testosterone levels to higher than normal for a person's age, provided that one maintains a healthy BMI above 19. If BMI drops too low, then testosterone (and IGF-1) drops so low that very little can raise it.The CR Way avoids that by emphasizing cell signaling rather than calorie restriction.
I have never seen sudden spikes in testosterone.
Hope that helps,
Interesting thanks Max. FWIW I have a BMI of 20 and have done intermittent fasting for over a decade, in addition to twice a year 1 week water only fasts. At 50 my testosterone started to drop below age adjusted 'normal' and persistently stayed there. Otherwise my health is superlative as I eat a whole foods vegan diet with a good balance of the macro nutrients, I lift weights, do Pilates, run and cycle. One small data point.
Good news is that with a topical application I've been able to bring the Testosterone up nicely :)
