On my hand, I encourage everyone I know who is interested in longevity to stick to actual scientific research and stay away from Mr. Johnson as much as possible. There are more red flags around this man than in the entire People's Republic of China. Let's make a small, non-exhaustive list of them:

1. First of all is that he talks significantly more about the supposed results of his program than he does about why his program is like that or even what does his actual program consist in. You will notice that nowhere at all is the actual "program" explained or even described in its entirety. As has been mentioned, all of his content is about "wow, look how amazingly strong I am" or "wow, look at my amazing metabolism" but none of it is actionable content beyond telling people to buy his shit.

2. Speaking of "telling people to buy his shit", once you get beyond the amazingly extensive wall of "wow, look how amazing my results are", his website looks remarkably like every single other unproven supplement peddler out there. I am looking at his website right now as I write this and the number of supplements he sells himself has, in fact increased greatly. He has gone from the $60 olive oil which was his original product to a branded line of spreads, drink mixes, and whatever else to the point that he's starting to look a lot like the Liver King (https://www.youtube.com/watch?v=BKpmAGZQetc), if more "creepy 50 year-old trying to look like a teenager" than Liver King's "creepy 50 year-old trying to look like a jacked piece of salami"

3. While I admire Mr. Johnson's willingness to self-test unproven treatments supposedly in order to figure out if they actually work for himself, his website is remarkably light on warnings on which treatments are actually unproven and which might actually carry some level of danger. The amount of warning on unproven and unlicensed therapies in his website amounts to a single footnote very well hidden under a gigantic wall of "wow, look how amazing my test results are and how impressive my wall of supplements is!"

4. Speaking of his test results, early on Mr. Johnson actually used to talk about challenges, things that went wrong or even just "not so great". As time went on, it's all rah-rah "look at how amazing I am! My measurements are better than an Olympic athlete!!". And while I truly do hope Mr. Johnson's (unexplained, just-so) protocol is just that great, it does seem a lot like peddling his olive oil and whatever else would suffer if he were to say that anything he did was anything beyond perfect.

5. Oh god, the "philosophy" parts. I really want to talk as little as possible about this one, because it's all vapid bullshit and even talking too much about it helps it spread - in fact Mr. Johnson is well-known for actively courting Twitter drama as a way to strengthen his brand. (It should be a well-known fact by any human being living in the 21st century that controversy will make grifters stronger in the short run). His rant on how he is somehow going from "First Principles thinking" to "Zeroth principle thinking", which is "the base of genius" can compete with anything written by any "motivational guru" who talks about "quantum healing" to large audiences... Including a part where he says that anyone who doubts him and his protocol must be weak, miserable, scared of being left behind, afraid of change, and lacking self-control. Wow.

6. Now, let's look at what all this high-minded philosophical talk builds up to. Well, it seems that somehow Mr. Johnson's protocol will help you resist "corporate profiteering at your detriment" and also stop us from "destroying the biosphere" by "aligning us with what the 25th century would value". Huh. Ok, seems pretty great. How can we get there, Mr. Johnson?

It would have been hard to predict the books that would be written with the introduction of the printing press; or what the internet would enable. The same principle applies to what the human race can become when paired with the torrid wave of technological and scientific progress. We can take baby steps as we work on stretching our imaginations:

Week 1: drink the Green Giant (GG) daily.
Week 2: GG + Super Veggie (SV) daily.
Week 3: GG + SV + Nutty Pudding (NP) daily.
Week 4: GG + SV + NP + supplements daily.

Oh, ok, we just need to buy his shit.

I rest my case.
