Yeah, most people who do keto or other low-carb variants tend to eat a high-protein diet. But for fat-loss something like twice as much weight of dietary fat as protein is recommended along with sub-30 grams of non-fiber carbohydrates. And the medical keto diet, iirc, was something like 4:1 fat:protein. It's a lot easier to hit the protein macros than the fat macros.
