Ketogenic diets evolved along the decades by showing results by practice but, most of all, also by science.
There are professionals, and, more than this whole organizations, that are making money with type 2 diabetes ketogenic therapy.
Hundreds of articles, systematic reviews, metanalyses, ..., lots of stuff related.
A stupdy, simple, cheap, 30-day random control trial with: 1) zero supplement keto group #1; 2) magnesium supplement group #2; 3) guar fiber supplement group #3; and i) people with no constipation under wertern diet...
How difficult is to do such experiment? We see Virta Health making money, we see Zoe Hardbomb talking more than 30 minutes and making jokes about beans, but no showing any evidence, we see Dr Ken Berry talking about an ancient experiment with western diet (and people with previous constipation), BUT... we just can't see any simple and miserable experiment!
Everything we can find is: individual opinions, magnesium supplementation, water, and salt. People feel ashamed to come back and say "it did not work for me".
