Greg Pomerantz: Salt and self-experimentation – #44
By: Dave Asprey
June 3, 2013
For Greg Pomerantz everything is a science experiment. He takes citizen science to a personal level by biohacking his blood pressure and detailing his data. He blogged about his self-experiment research on salt clarifying some misnomers he had about salt’s effect on the body. He determined what his salt type is, either one is salt sensitive, or one that isn’t affected much by increases in salt. He discusses how to do that in today’s podcast.

Bonus Client Review with Jonathan Kos
Jonathan Kos is an IT professional and a recent follower of the Bulletproof Diet. He is a 44 year old IT professional . He is a former college athlete that played football, and competitive ice hockey up until the age of 25. At 6’3” he was an extremely fit 220 lbs and his coaches wanted him to weigh in at 275 to play the defensive line so he was eating literally non stop to put weight on. After college he dropped down to around 200 lbs and eventually settled at a healthy 235. As he got older and more settled in his job, his weight climbed and he couldn’t keep it in check with exercise alone. He started to diet and was up to 300 lbs- he was exercising more than ever but the weight didn’t come off.
After he met his wife, exercise went out the window, a carb heavy diet was in, and his weight ballooned up to 365lbs. He was about to give up until he heard Tait Fletcher on Joe Rogan’s podcast mentioning Bulletproof® Coffee and he gave it a shot.
He lost 45lbs in 45 days, and is here to share his experience with you.
