‘If you fast and eat Keto your body will burn fat, not muscle. Stop spiking your insulin with 3 meals a day and constant snacking’
Correct. The probem with keto is it’s very easy to ‘fall out of the wagon’ especially for people used to constant snacking. Not to mention the problems with oxalates (joint pains and kidney stone risk). With carnivore, none of these inconveniences exist, you can snack as often as you want and intermittent fasting can come naturally (I personnally eat 3 meals per day at fixed hours, never snack but can skip a meal without any craving). That why a lot of ketos become carnivore to be more consistent and have better results.
I cycle in and out of carnivore. After about two weeks I crave vegetables so I do a lot of them for a while, then back to meat. I call it bunny/tiger eating.
Most people fail at keto because they never get their fat ratio high enough. A lot of people are very stuck on fat is bad and just don’t put enough olive oil or butter on their food.
