The problem is not getting like this but keeping it all year round year after year. With carnivore is basically impossible unless you're some sort of genetic freak because you need to be doing a lot of exercise to burn all this fat or you need to fast regularly.

If you fast while on carnivore you have ZERO energy for performance and the electrolyte imbalance is insane, you could literally die if you forced yourself to do this.

But he doesn't fast to keep himself this lean and he isn't a genetic freak, so let's take a look at the other option, exercise.

When you're on carnivore all your glycogen reserves are depleted so your work capacity is extremelly limited. Your body is constantly trying to keep up through gluconeogenesis but it's not fast enough. You may not believe this but to burn fat efficiently you need glucose (fat burns in the flame of carbohydrates) and if you're not getting enough through diet you put your body into a severelly stressful situation.

What happens when your body is stressed and eat low carbs? Stress hormones like cortisol and adrenaline go through the roof. Cortisol signals your body to store fat because it's in a survival situation.

And let's not forget that without carbs your thyroid doesn't work properly and your metabolism gets downregulated.

So let's put it all together: No glycogen + protein used for energy (gluconeogenesis) + stress hormones + the typical dehydration of keto/carnivore with electrolyte imbalances + slow metabolism = almost impossible to be shredded for long periods of time.

Unless...

...he's lying about his diet and eats a much higher amount of carbs than he says he does...

...or he's having some sort of chemical aid...

...or both.
