In this video, produced by Vox in early 2018, the writer gives you reasons why all diets fail, evidence that most diets are fads, and some of their ideas about a Ketogenic diet. It is doubtful that the author ever did try the keto diet but likely did some investigation or research into the topic. The video does serve as a good introduction to what the keto diet is, even though some of the historical contexts of the diet is lost. In any case, it’s worth watching and part of your continued learning about the Keto diet.
