I would say the most epic fad diet of all time is the Standard American Diet, something that was basically "invented" from the weakest evidence, heavily influenced by corporate interests, politics and still perpetuated to this day despite skyrocketing rates of chronic preventable disease and obesity.

To call a keotgenic diet a fad diet as happens in every HN thread seems to ignore the precedent that ketosis was the primary metabolic status for our ancestors for millions of years. If it wasn't, why are our bodies so precisely designed for it..Just random chance? I dont think so.

Due to food scarcity, not due to abundance of protein sources. The current keto diet is light on fasting and heavy on chicken and steak, which I think is the “fad” portion of OP’s comment. There are tons of negative things about jacking of animal protein intake that do not exist in a fasting focused keto diet.

All of our habits post-Agricultural Revolution (like grain) have been a fad in evolutionary terms.
