Similarly 29% fat is not low fat. That's pretty much a "normal" diet (i.e. what the mainstream advocates). Also, the low fat diet is 23% protein - over 100 grams for the similarly restricted 1600 calorie diet. Again, that's a mainstream advocated diet. I've seen plenty of diets that advocate never going over 100 grams of protein. But, my experience with dietary studies (it's a kind of hobby of mine to read them), many have serious methodology or analysis problems. The study they are referencing is this one: https://www.ncbi.nlm.nih.gov/labs/articles/28027950/ https://www.ncbi.nlm.nih.gov/labs/articles/28027950/ which you will notice is published by Elsevier -- which means I can't read it. The abstract does not fill me with confidence, as it is very light on details.
