Michael Greger & How Not to Diet: The Complete Guide

Calorie density, accelerators, and how the 2019 book sits next to Fung and Bikman

How Not to Diet (2019) is NutritionFacts aimed at weight: calorie density, fiber, insulin index, and a long accelerator list. The useful protocol is still plants and fewer ultra-processed calories. This guide extracts the grocery move and flags where twenty-one levers become a personality.

Calorie Density

Moderate Evidence

Fill the stomach with foods that carry fewer calories per bite — vegetables, fruit, legumes, intact grains. That is the mechanism that survives the citation fights.

Ultra-processed food is the opposite: easy calories, weak satiety. Steal that sentence even if you keep olive oil and fish.

Accelerators

Emerging Research

Vinegar, spices, sleep, timing. Pick two. Do not run a 21-item dashboard.

If insulin is the actual lab problem, read Bikman and Fung next — not another spice aisle.

Keep vs Skip

Moderate Evidence

Keep: beans, greens, walking, B12 if vegan. Skip: treating the book as a reason to drop protein after 50, and stopping a prescribed GLP-1 because a hardcover explained cabbage.

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.
