How to Calculate Keto Macro

What is Keto Macro?

The ketogenic diet requires very low carbohydrate intake (typically < 20–50g net carbs/day) to induce ketosis — a metabolic state where the liver produces ketone bodies from fat as the primary fuel source, replacing glucose.

Step-by-Step Guide

  1. 1Standard keto macro split: 70–80% fat, 15–25% protein, 5% carbohydrates
  2. 2Protein: 1.2–1.7g per kg body weight to preserve muscle
  3. 3Carbs: < 20–50g net carbs (total carbs minus fibre) per day
  4. 4Remainder of calories from fat
