The Proper Human Diet, or PHD, is the way of eating humans thrived on for most of our history: whole animal foods and natural fats, with very few carbohydrates. You build your plate around meat, eggs, and fish, add natural fats like butter and tallow, and keep total carbs low. Vegetables and dairy are optional. There is no calorie counting and no deprivation. You eat real food until you are satisfied.

Start with one meal. Build a plate around a fatty cut of meat, eggs, or fish, cook it in a natural fat like butter or tallow, and skip the bread, pasta, rice, sugar, and seed oils. Do that for your next meal too. You do not have to be perfect to get better. Download the free Proper Human Diet Guidebook for a simple plan you can follow from day one.

You can get the Proper Human Diet Guidebook for free on the guidebook page. Enter your email and we will send it straight to your inbox as a PDF. It walks you through what to eat, what to avoid, and how to start, all in plain English.
