About the PE Diet Calculator
This calculator is based on the formula described in the book The P:E Diet by Dr. Ted Naiman. The Protein-to-Energy (PE) ratio measures how much protein a food contains relative to its non-protein energy (fat + carbs − fiber).
A higher PE ratio means a food is more protein-dense, which supports satiety and better body composition. Foods with a PE ratio above 2.0 are considered excellent choices for fat loss.
Pair this with the TDEE Calculator to estimate your daily calorie needs, then use the Macro Calculator to set your protein, fat, and carb targets.
