I didn't see my doctor between moving from keto to carnivore, and settling into carnivore about a year later, and described it as "very low carb"
He told me I would be dead in a year if I didn't go on statins due to high cholesterol I said no thanks, please look up the cholesterol-energy hypothesis; my cholesterol is moving my fat to my muscles.
I don't think he has yet looked up the cholesterol-energy hypothesis
Atkins wasn't no carb. The most restrictive Atkins diet required 20g of net carbs per day, and it got less restrictive quickly.
Internet keto follows the most restrictive Atkins diet, or sometimes limits people to 20g total carbs (as opposed to Atkins' net carbs). Medical keto is like internet keto but adds highly ketogenic MCT fats
The only people prescribed medical keto are those getting it for mental illness, diet tests usually use internet keto
