I don't follow him or know much of his content but I actually have a somewhat positive memory of him when people on social media got angry with him saying that suicide often isn't necessarily linked with depression. While he might be pro-life and YouTube-Mainstream-friendly he at least made a statement that set him apart a bit
Edit: found the clip:
This video made me respect him a bit more as well, even though I don't vibe with a lot of his other content (particularly those pushing meditation and alternative medicine ideas) I can admire his stance towards separating suicidal ideation from a solely depressive state, as few prominent figures are willing to acknowledge such an idea.
I also think it was pretty unfair to him that he was immediately blamed for the death of his guest that conversed with on livestream, although he handled it poorly, when the man had clearly been suicidal for a long time. The general public saw having an open conversation about his issues (albeit potentially profiting off of it by televising it to the world) as "offering unlisenced therapy" which begs the question, is giving advice/support to a friend about mental health issues something that is going to become inherently monetised and strictly regulated to "professionals"? It feels like we're living in such a grim reality.
Other than that, I don't really like his content that much either. Obesity and addiction are very complex issues, that often aren't as simple as making lifestyle changes especially if there's some underlying issues. A lot of people who are on psychiatric medications will go through metabolic changes as a result of that. Our eating habits are fundamentally governed by a complex interplay of hormones and sensory cues, and one's environment as well as medications or lack thereof can impact that, as well as overall metabolism. I can bet a great deal of Dr. K's audience are probably taking such medications and might not have been fully informed of the potential side effects.
I think most people like to believe in the idea of having full control over your health and your life, and watching content like this can be motivational and reinforce the idea that if you are in the right mindset you can achieve many things of your own free will without assistance. See the disgust that many have towards others taking appetite suppressants like ozempic, as they see it as cheating and not "doing the work" of going to the gym etc. When ozempic can be a truly life changing medication for weight loss, and get certain people back to a healthy weight quickly. Yet, taking a drug is seen as taking the easy way out/pathetic, even if it could drastically improve someone's life.
The type of content Dr. K produces can certainly resonate with a lot of people, especially those who are geared towards self-improvement messages, but if you're the sort of person who has been let down by such content before and lifestyle changes alone haven't helped us, we don't really connect with it as much.
I also have a friend who highly praises Dr. K and gets angry and defensive with me when I say meditation makes me feel worse instead of relaxed, and acts like my own feelings regarding such methods are invalid, "because Dr K knows better than you" so I can understand your frustration with youtube gurus quite well.
