Enjoyed this. Caulfield is a heath researcher in Canada who I had previously not known that much about but I guess he’s hot shit in his field. This book attempts to look at the science behind many of the health claims we deal with in the modern world and not in that “Here are the facts that support the fad that I am currently publicizing” way but in looking at the analysis and meta-analysis to help answer questions like “Wat is the best way to lose weight?” and “Is there any proof that naturopathy works?” and “What’s the best way to exercise?” Along the way Caulfield uses himself as a guinea pig, getting his genetics tested and going on a healthy diet and talks to many other professionals in the field to get at what is really going on and why we might not be getting the best information from the media we consume. I enjoyed it. Caulfield is engaging as a writer and the stuff he says mostly makes sense. People interested in health who are sick of the usual New York Times analysis of current food and exercise trends and reporting will find this a breath of fresh air.
