IMO the Carnivore diet:

Starve the bacteria of their carbs.

Integrate anti-inflammatory spices.

Reduce pancreas workload.

Slow energy absorption.

Increase insulin sensitivity.

Reduce adipose(fat) tissue.

Feel fuller.

As long as you don’t accompany the meat with sugars or starches. Also consume easily digestible proteins like beans, fish, and chicken. Or slow cooked beef(80% human dna eeew).
