Look into the keto diet. Fat is definitely not the main issue, sugar and other simple carbs are.

Your conclusion presupposes we buy into the "keto diet is healthy" proposition.

However, there is a preponderance of real data that fats have been demonized by the sugar industry in the past, and HGI foods (high-carb, generally) are a bigger issue.
