Good Calories, Bad Calories: Fats, Carbs, and the Controversial Science of Diet and Health

Good Calories, Bad Calories: Fats, Carbs, and the Controversial Science of Diet and Health by Gary Taubes

The author of Good Calories, Bad Calories is strongly in the "carbs are bad" camp, however, he presents his argument with a fairly open mind. He believes there is adequate science out there to support the low-carb diets. However, it has been suppressed. 

There are multiple reasons for this suppression. There are some researchers that have received money from companies that pedal sugary food. This leads them to favor sugar (as opposed to fat.) There was also a loss of key German nutrition research after the world wars. Scientists have jumped to conclusions after limited studies. Then they have seen repetition of their initial hypothesis. Government policy was put in place before the science was settled. This advocacy for low-fat diets ended up biasing future work. Science disciplines are also very narrow and don't communicate well, limiting the view of what he sees as the obvious solution.

The criticisms of science are all valid. The advocacy for low-carb diet is also fairly convincing. However, with the thoroughness, you could easily advocate for just about any diet. He goes for the Occam's Razoer argument. Carbs are the simple solution, so they must be true. However, he also ties it with the argument for hormones and genetics. If it is our body that is controlling weight gain it why bother with what we eat? How is it that exercise doesn't matter?  

There are also challenges about grouping things together. Are all carbs bad? Are the groupings appropriate? What are the causes and effects? Do people really eat because they or predisposed to get fat?

Nutrition is complex. People have been getting fatter recently. Modern processed junk food seems closely correlated. But is it causation? Or is there an external factor? 

The book is a good exploration of low carb diets by a science writer. Will we ever have a solution to diet that maximizes health while also preserving the environment and economy?

Change Your Diet, Change Your Mind: A Powerful Plan to Improve Mood, Overcome Anxiety, and Protect Memory for a Lifetime of Optimal Mental Health by Dr. Georgia Ede MD

I had hopes that this book would be a good analysis of diet and mental health. Alas, it was a diet book pushing the keto diet. The author would proclaim that we cannot trust any epidemiological studies because they are not good randomized, controlled studies. We also could not trust pronouncements of the benefits of certain diets because they had not been studied enough. Instead, we should just focus on an all-meat diet because it is "natural". We should trust that it is good because there have been no big studies on it. Wait? Didn't we just criticize other diets as being bad because there were problems with the studies? Oh, but for keto diets, the problems with the studies mean that they missed out on it being good. It just comes across as selective analysis to push a certain diet. 

There are some good points, but even they are not without issue. It is easier to get the nutrition we eat while just consuming meat without supplementation. But if the world would do that, we would probably be driven to cannibalism after we had used up all land and driven wild game to extinction. The author tries to spin other studies on their head. The compounds that plants produce that are supposed to help us fend off bad things? Well, plants make them to fend off pests, so they must be bad for us also.

At times the author does try to be balanced. There are even some attempts at vegetarian-type keto diets. But, it does feel half-hearted. The key point is that super-processed food is not so great for us. Beyond this book just schills a diet with confused and contradictory scientific logic.
