Ben Greenfield is widely recognized as the leading influencer in the biohacking space. The New York Times bestseller, podcaster, educator, and all-around biohacking God sat down with us at the Biohacker Summit in Toronto, which Prime helped put on, to share his knowledge after spending most of his life immersed in researching how to optimize himself, experimenting on his own body to test the results of his research, and sharing those learnings with those who are interested. Here are his top three biohacks that are free and simple for you to implement immediately:

1. Combine a lot of sunlight exposure with high intake of minerals.

2. Subject yourself to cold stress daily.

3. Intermittent fasting for 12-16 hours daily.
