The definition of 'ketogenic diet' is broad and can encompass very high-fat diets, medical ketogenic diets, low-carb diets, and protein-sparing fasts, leading to potential confusion in research interpretation.

“has Quito and ketogenic diets I think can mean so many things yes and there are people doing very high fat keto which could have 70% or more of your fat comes from or 70% or more your calories come from bad I mean is there I don't know your other definition I think there's like this medical ketogenic diet with 4 to 1 protein ratio in terms of grams that is used for kids with epilepsy yes many people who are doing low-carb and that's where it originated from the ketogenic diet exactly procedures and then and that a lot of people will refer to members of protein sparing fast exactly which is totally different yeah but people will refer to those old studies with medical ketogenic diets which were a four to one ratio okay and that is going to have different physiologic effects on the body because it's not enough protein right yeah they're very low protein”
