You do you but I would never recommend either Keto or Carnivore. I’m a proponent of dietary guidelines that can be sustained for life instead of dietary yo-yo’s, because you will almost certainly bounce back the other way.
Difficult to explain succinctly and I will elaborate if I get to a journal but right now I’m at my daughters soccer game, not paying very good attention apparently.
You get to the point where you have high motivation to change. Generally you are overweight or sick. That’s your current reality. You have a strong motivation to not be sick or overweight so the ideal you is far away. There is tension between your reality and your desired outcome. Your brain naturally wants to resolve that structural tension. You do carnivore or some other extreme diet. You make some progress. The tension is no longer present so You lose motivation. You stop the diet. You slide backwards again, statistically speaking often worse off than before, due to other structural tension models that exist such as, I’m really craving junk food right now and it just so happens I have a ton in my pantry. Makes it easier to resolve that structural tension conflict than the one where you’re only slightly overweight or not so terribly sick anymore.
Diets don’t work.
If you consciously decide to take on the identity of a healthy person, then there are many small, gradual, sustainable changes that can be made for life long health. With identity you can make better decisions every moment of every day. There are additional processes like implementation intentions that can ease the burden of trying to willpower everything.
This all deserves a much, much longer explanation than I can thumb on a phone in ten minutes. More to come I guess…,
