Plenty of studies on ketogenic diets on rats are based on adding an incredible amount of fat on top of carbohydrate heavy and call it ketogenic. /r/ketoscience has these crappy studies posted and debunked daily. Serious research on low carb is sorely lacking and plenty of interested parties really do not want for good science to be done around high fat/meat: the money's on plant based these days. I am still salty about that sorry excuse for a study the Lancet posted a few years ago and is still making headlines.
