A four-to-one ketogenic diet (e.g., 400g fat, 90g protein, 10g carbs) is a very high-fat version.

“I mean for looking like the Hopkins ketogenic diet where it's it's four to one fat to protein and carbs in terms of I think by weight so if you're eating a hundred grams of protein and carbs you're eating 400 grams of fat which is 3600 calories so you're looking at four thousand calorie diet probably close to what you maybe where you're doing but 75 grams of protein maybe 25 carbs maybe lower and you're doing that and you don't realize like that does take effort it's not just like I'm just gonna eat some meat”
