Keto is a pretty broad term. Typical keto is MINIMUM 65% fat, usually higher, and really a pretty moderate/normal amount of protein. Though, to be ketogenic, you really just need an absence of carbs.
The palumbo cut diet is much higher in protein than the typical keto diet, with the fats carefully balanced with each meal to keep you in ketosis.
I’ve been off the wagon for about a week, will resume in a couple days. But I lost 23lbs and about 5.5” on my waist in 8 weeks. I felt great, just got to the point of being sick of eating the same couple things every day. A bite of any of it literally makes me want to throw up anymore.
