Keto diet focuses on carbs in general, irrespective if the source of the carbs is sugar, wheat or broccoli.
It seems to me that for many people, this approach can be further optimized. Of course, there will always be people who cannot eat vegetables (the daughter of Jordan Peterson), but in my limited experience, these are very few in number.
In general, most people I know of have problems with sugar and wheat, but no problem whatsoever with vegetables.
So, I do not understand why there is no a diet which is similar to keto (low in sugars and refined carbs, high in fat, moderate in protein) but accepting carbs such as vegetables, for example (there could be a discussion with fruits and legumes, for sure).
Is there an explanation for this?
