I find most of his videos, which typically follow the format of "I conducted experiment X on myself; here are the results," useful and digestible without being overly pushy about selling his Blueprint product.

The sample size = 1 person (himself) casts doubt on a lot of his findings, but I've still made some lifestyle changes after watching his videos. I finish eating earlier, and anecdotally feel better. I've leaned toward eating more healthy nuts and extra-virgin olive oil, and I've also purchased a sleep tracker.

I have not made any Blueprint purchases.
