SUMMARY: This is a comprehensive review of 53 studies to evaluate the effectiveness of low fat and high fat diets. Results of the studies showed that low fat diets do not work better than other diets with higher fat/lower carbohydrate content.
LESSON COMMENTS: With all the confusion on the internet about the various types of diets (Atkins, keto, paleo, etc.), this paper approaches diets in a way that is not usually done by diet companies. By looking at multiple experiments and their results, the conclusions drawn may be more telling than the results of a single experiment. This paper addresses the way experiments were chosen and which ones contained more valid results and why. The discussion section in particular is a good section to read.
