Jonathan Kos is an IT professional and a recent follower of the Bulletproof Diet. He is a 44 year old IT professional . At 6' 3" and a former college athlete that played football, competitive ice hockey up until the age of 25 he was an extremely fit 220 lbs and my coaches wanted me up to 275 or so to play the defensive line so I was eating literally non stop to put weight on. After college he dropped down to around 200 lbs and eventually settled at for me was a healthy 235. As he got older and more settled in his job, his weight climbed and he couldn’t keep his weight in check with exercise alone and he started to have to diet he was up to 300 lbs and was exercising more that ever but the weight didn’t come off.
After he met his wife, exercise was 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 day
