From your point of view, I can definitely set why you say that grains are suboptimal. In context, they are better than starving, and certainly weren't preferred. 
Thank you! I'm definitely better off that I have been, and being lighter is definitely a benefit for pretty much everything.  

 I think this tracks better with what I've learned about insulin over the years.  

 In the absence of carbohydrates they are insulin sensitive, but I said physiologically insulin resistant, meaning they likely won’t pass a glucose tolerance test. I’d argue that it’s better to be insulin sensitive at all times and not just when eating certain foods.

On the “correct amount of hormones” many men doing a carnivore diet experience a decline in testosterone levels and some even have worse sleep (too much cortisol?). Many try to explain it away, but that has the same vibes as vegans telling ex-vegans that they didn’t do it right.  

Humans are unquestionably omnivores, and many of us are quite resilient and can thrive on many different diets. Some are less resilient and have to stick to only eating meat, but to say humans didn’t eat fruits and other carbohydrate containing foods, specially those living close to the equator, is just false.      

Insulin spikes are not inherently dangerous. As long as one is insulin sensitive they can be beneficial for nutrient delivery, and insulin itself is anabolic (muscle growth) which is beneficial for obvious reasons.

 I’ve listened to him and the rest of the carnivore gang. Was deep in the health rabbit hole between 2013-2020

Yep, the carnivore diet is a great tool/medical intervention to fix an array of ailments

What I’m saying is that not everyone is broken 

 It’s the optimal dietary path. You’re wrong on some things in your previous reply but I don’t have to explain it, Chaffee does a great though. Best of luck. 

 I think you’re blinded by the cult. No shame, I was too at one point.

Optimal for what? 

Weight loss? Sure
Athletic Performance? Probably not
Fertility? Questionable 
Muscle growth? No
Addressing autoimmunity? Yes 

It’s all good, at end of the day what matters is ones N=1. People know what works best for them 

 I also have some issues with assumptions that carnivore is best for what ails women as a direct corollary that it's best/more gooder for men (long term or life long). 

I don't think that it can be easily disputed that some modern humans are so screwed up that eating only ruminant meat is the only way that they can survive in a way that doesn't cause their bodies to try to moidalate (yes, that's a VERY technical term 😁) their own body every time they try to introduce plants into their diet.  

 No, I just accept the most credible evidence. 

But for me (n=1) since I cut out all modern foods and simply subsist off fatty ruminant meat I’ve: gained muscle, lost fat, hit PRs in every lift in the gym while not working out as often, I objectively heal faster, my “itis” have vanished, low-grade nerve pain also resolved, my silent reflux is gone, my dandruff has been reduced by 90%, my skin is flawless, I can go all day without eating and put in extreme effort while doing so, and my sleep has improved to a point where it is perfect - fall asleep every night in a few minutes and wake up 7.5 hours later no alarm like clockwork. 

Being a sugar / carb / vegetable clown (who still ate meat) in my previous life had lead to all those health problems. Eating optimally relieved all of them over the course of a couple years. Remarkable. 

 How long have you been carnivore?  

 Just under 2 years. I was low carb but still making smoothies daily. Finally cut them out a couple years ago and experienced a big difference. 

 Dang! Go you!
