I think genetics may have something to do with it. Anecdotal personal evidence: my father was fundamentally a meat eater, and only ate twice a day. When he saw me eat salad he asked me when I’m going to start eating food. Not “rabbit food.” He was 10 pounds within the same weight throughout his adult life. My mother was mostly vegetarian with tiny bits of meat occasionally. Her weight fluctuated maybe 20 pounds throughout her adult life.
When I was 28 years old I tried the Atkins’s diet (in those days daily ketosis was required, for me 4 carbs a day or less) after 3 months I almost died from being overly weak etc. The doctor said I had extremely low potassium. I did lose any amount of weight I wanted though. My father never had low potassium and he was always active. My mother was a ranked gymnast. I am neither. And a vegetarian diet leaves me very low in iron although I try to compensate for it.
My observation is that genetics may influence what kind of diet is best for you.
