Protein-ledUpdated Apr 26, 2026

High-Protein Diet

High-protein eating supports fat loss, muscle retention, appetite control, and recovery, and it pairs with nearly any food preference. The hero number is per-meal: 0.4 g per kg of body weight, four times a day.

Macro splitUpdated Apr 26, 2026

Keto Diet

The keto diet is a very low-carb, high-fat approach that pushes the body into ketosis, a metabolic state where ketones provide a larger share of fuel.

Whole-foodUpdated Apr 26, 2026

Mediterranean Diet

The Mediterranean diet is the most studied way of eating in the world, and the most misunderstood.

Medication-pairedUpdated Apr 26, 2026

GLP-1 Diet

If you're taking GLP-1 medications like semaglutide (Ozempic, Wegovy) or tirzepatide (Mounjaro, Zepbound), your relationship with food has probably changed dramatically.

Low carbUpdated Apr 26, 2026

Low-Carb Diet

A low-carb diet restricts carbohydrates and leans more heavily on protein and fat.

Low fatUpdated Apr 26, 2026

Low-Fat Diet

An honest, spectrum-based guide to low-fat eating, from general guidelines through Pritikin, Ornish, and Esselstyn, plus the medical indications where fat restriction is genuinely first-line therapy.

Heart-healthyUpdated Apr 26, 2026

DASH Diet

The DASH diet stands for Dietary Approaches to Stop Hypertension, and it's the most rigorously trialed eating pattern ever built around blood pressure.

Plant-forwardUpdated Apr 26, 2026

Vegetarian Diet

Vegetarian eating done well: the easy mode of plant-based diets with eggs, dairy, and the Adventist Health Study 2 longevity data showing 12% lower all-cause mortality. Plus the protein-combining myth, hidden animal ingredients, and a 4-week transition plan.

Plant-onlyUpdated Apr 26, 2026

Vegan Diet

A well-built vegan diet is one of the best diets ever studied for human health.

Weekly cadenceUpdated Apr 26, 2026

Slow-Carb Diet

Tim Ferriss popularized the slow-carb diet in The 4-Hour Body in 2010, and it has stayed relevant because the structure is unusually clear: a short list of allowed foods, five rules, and one day off per week.
