Metabolical

Summary

Metabolical by Robert Lustig, MD (2021) makes the case that the modern chronic-disease epidemic is fundamentally a metabolic disease driven by dietary and environmental insults to cellular energy processing. The book is organized around eight cellular pathologies (the eight modern metabolic disease pathways) and traces how processed food, added sugar, ultra-processed food, and modern stress load converge on them. Lustig also covers the regulatory and industry context that has kept these patterns in place, and a clinical-style treatment framework that prioritizes dietary intervention over pharmacology for the metabolic components of chronic disease.

About

Robert Lustig is a pediatric endocrinologist (UCSF), emeritus professor, and author of Fat Chance (2012) and Metabolical (2021). His work focuses on the dietary and metabolic drivers of chronic disease, particularly the role of added sugar and ultra-processed food in metabolic syndrome and pediatric obesity.

Why I recommend it

Lustig's case for treating added sugar and ultra-processed food as the upstream metabolic insult — rather than treating each downstream disease (obesity, diabetes, cardiovascular disease, fatty liver) separately — is the framing I lean on when patients ask why their metabolism broke in the first place. The book is a useful next read after Ultra-Processed People and Good Energy.
