Keto people tend to be too reductionist on carbs and macro nutrients and insulin response. Carbs shouldn’t be a euphemism for junk food. And the potato is the most satiating food at 90% carbs.

From personal experience keto has convinced binge eaters that they need to wear a CGM and avoid foods like beans and carrots, foods they weren’t eating much of in the first place but probably should eat more of.
