When the keto diet first skyrocketed in popularity in the late 2010s, it quickly gained a reputation as the “bacon and butter” diet. Vegetables might appear on one’s plate as a small side of spinach or, more likely, cauliflower masquerading as everything from rice to pizza crust to wings. By and large, the focus was on limiting consumption to “keto vegetables” while focusing mainly on increasing fat intake. (I’m talking mainstream keto, mind you, not the Primal Keto Reset approach.)
This, as you’d expect, led to no end of pearl-clutching from mainstream medical professionals and the popular media, who quickly branded keto as a dangerous fad diet, a heart attack in the making. It was true that many early adopters of keto went hard on butter, cream, cheese, bacon, and other high-fat foods, probably as an understandable backlash against the low-fat diet dogma that dominated the previous four decades.
