People feel better on meat-only diets because they stop eating junk food—not because meat is magical.

Improvements in metabolic markers and weight loss observed on extreme low-carb or carnivore diets are primarily attributable to caloric restriction and elimination of ultra-processed foods, not to the physiological properties of animal-based foods alone.

Eating only animal products might help balance your hunger hormones so you naturally eat less and lose body fat, especially if you're overweight.
