You can't solve a problem if you don't know what it is. One of the exceptional advantages of Lustig's book is his ability to "connect puzzle pieces" for the average reader to uncover the science and concepts behind his arguments when he tells "the whole truth about food. "This book combines topics such as nutrition, health, medicine, the environment and society into a completely new relationship. The war between vegan and keto is a phony war: fighting on the same side. Arguing that food is the only lever we have to induce biochemical changes to improve our health, Lustig explains what to eat based on two new criteria: protect the liver and feed the gut. He insists that if we don't fix our diets and change the way we eat, we will continue to cause chronic disease, bankrupt healthcare and threaten the planet. But there is hope: this book explains what it takes to fix all three problems.
