Fat Fast macros?

I know people will say they are fat fasting when they eat just fat. It does not provoke an insulin response unless you eat a great deal. Something like coconut oil in coffe would be considered a fat fast.... This is just my interpretation though.

In that light, a fat fast could be 100% fat, 0 carbs and zero protein.

I do IF with just fat (up to a couple hundred calories) until mid afternoon on most days.

I read off of https://ketodietapp.com/Blog/post/2014/08/14/Complete-Guide-to-Fat-Fast

"Fat Fast is a type of fasting often recommended for those who are already keto-adapted and reach a weight loss plateau. The idea is that you eat about 80-90% of your calories from fat while keeping your calorie intake low, up to 1000-1200 kcal a day. This fast should be followed for no more than 3-5 days."

Hope this helps!
