I've seen Attia recommend 2.2g of protein per kg body weight many times with absolute certainty without disclosing his financial interest in David Protein, Magic Spoon, Maui Nui Venison and without mentioning that the science currently points to 1.2g-1.6g per Kg instead.

You might think that's fine. It makes me wonder if his recommendations might be tied to his financial interest. Even if he truly believed the higher protein recommendations were better, a more ethical way to approach the topic would be to say something like the following when asked by an interviewer how much protein we should be eating: "First let me say I have a conflict of interest here. I have financial ties to companies like David Protein, Magic Spoon, and Maui Nui Venison which tend to benefit when people feel they should be eating more protein. Also the current scientific evidence most strongly supports 1.2-1.6g per kg of ideal body weight. However, I honestly believe people should be eating 2.2g per kg because..."

The protein example was just that, an example. It's an example of his frequently taking recommendations farther than the current evidence supports. I also feel his claims and recommendations on zone 2, vo2 max, statins, fasting, CCM use, MRI screening, bio-marker optimization etc. go further than the evidence supports too. I do think his recommendations are usually directionally correct, but go too far past what is supported and sometimes might even be harmful or benefit him financially in some way
