Key Moments

Best blood work in a decade: IF after 3-4 weeks of keto produced high testosterone and strength gains

Ferriss was skeptical of IF after DEXA data showed people losing muscle mass. But after 3-4 weeks of strict keto followed by intermittent fasting, he got his best blood work in over a decade -- including high testosterone, strength improvements, and muscle mass gains.

"I began doing intermittent fasting after three to four weeks of strict ketogenic diet. And had the best blood work I have seen for myself in more than a decade."
