Knowledge: Passing judgment without understanding the concept of intermittent fasting may lead to misconceptions about its benefits while the idea of keto is to get the body in a state where it burns fat for energy instead of carbs

Conversation:
My fiance is trying this new ketogenic diet, but I am not sure what kind of foods are allowed on it
Well, I know that there is high fat, low carbohydrates and adequate protein
I know some people who swear by it.
It works for some people although it can be a tough adjustment for sure. But some people adapt after the intial phase
I guess it's one of those things one needs to try first before passing judgment. What is the whole concept about?
