Has anyone heard of Dave Asprey, better know as the Bulletproof Executive? He was on the Joe Rogan podcast this week and made a ton of outlandish claims. He runs the website www.bulletproofexec.com and describes himself as a "bio-hacker who takes self-quantification to the extreme of self-experimentation." Apparently he has spent $250,000 on experiments where he is the guinea pig and claims he has ">20 IQ points, lowered his biological age, and lost 100 lbs without using calories or exercise." He is a big proponent of avoiding grains completely, eating a ton of grass-fed beef, a lot of grass-fed butter and saturated fats, and states that calories have zero effect on weight. He even claims that when he was in his late teens he would eat under 2000 calories a day, exercise 6 days a week for an hour and a half each time and still weighed 300+ pounds. Then he started eating 4500 calories per day and stopped exercising and all of a sudden lost 100 pounds and got a six pack. This was due to eating the "right" foods like saturated fat. Anyway I'm not educated enough to refute his outlandish claims but I would appreciate if you guys could check out his website, watch some of his videos and comment. Thanks guys.
