Metabolical
Robert H. Lustig's 2021 book argues that the modern epidemic of metabolic disease, diabetes, fatty liver, heart disease, and a long tail of cancers, is not really an epidemic of personal weakness but an epidemic of processed food. Lustig, a pediatric endocrinologist at UCSF who became famous for his viral lecture Sugar: The Bitter Truth, walks the reader through the biochemistry of what happens when the liver is repeatedly hit with industrial sugar and refined seed oils, why ultraprocessed food drives both undernutrition and overconsumption at the same time, and why the standard advice to simply eat less and move more keeps failing. He then turns the same lens on the food industry, the medical establishment, and federal policy, naming the incentives that keep Americans sick. The book is opinionated and dense with citations, and it has become a touchstone for the broader debate about food as medicine.
