Stephan Guyenet & The Hungry Brain: The Complete Guide

Appetite circuits in a snack environment — change the cues, skip the shame

The Hungry Brain is obesity researcher Stephan Guyenet on why ancient appetite circuits overeat modern food. The Amazon listing here is the Flatiron paperback (1250081203), not the 2017 hardcover. This guide pairs it with van Tulleken and Fung. It is not a macro war and not a GLP-1 stop card.

Stephan Guyenet & The Hungry Brain: The Complete Guide

Who this is for

  • ·Readers comparing Guyenet vs van Tulleken vs Fung
  • ·Anyone tired of willpower lectures
  • ·Gift buyers for a relative who already ‘knows what to eat’
Advocated by
Lustig / Fung readersPeople who know the diet and still overeat

The Brain, Not the Lecture

Moderate Evidence

Palatability and food reward pull harder than a resolution. Leptin resistance is the biology chapter. The practical move is fewer cues on the counter.

Van Tulleken names the factory food. Fung names the insulin clock. Guyenet names why you still reach.

What to Change

Moderate Evidence

Sleep, walking, and not stocking the snack. This book does not referee keto versus vegan. Both fail in a house built for overeating.

Keep vs Skip

Moderate Evidence

Keep: the environment edit. Skip: stopping a prescribed GLP-1 because a paperback explained reward, and hunting the hardcover if the paperback is the live listing.

The Obesity Code: The Complete Guide

The Obesity Code made intermittent fasting sound like endocrinology instead of willpower. The keepers are fewer snacks, fewer liquid sugars, and a daily eating window. The danger is fasting on glucose-lowering drugs without a clinician. This guide places Fung next to Longo and modern IF practice.

Robert Lustig & Metabolical: The Complete Guide

Metabolical (2021) is Lustig’s case that chronic disease is more foodable than druggable. Two rules: protect the liver, feed the gut. This guide extracts those rules and sends you to Bikman, Fung, Means, and Fiber Fueled — not a keto-vs-vegan flame war.

GLP-1 Agonists: The Complete Guide

GLP-1 receptor agonists (semaglutide, liraglutide) and dual agonists (tirzepatide) moved from diabetes clinics into mainstream weight and metabolic culture. For biohackers, the live questions are muscle loss, rebound weight, nutrient quality, and whether a peptide drug belongs next to Zone 2 and protein. This is a map of the evidence — not a shortcut to a vial.
