What Is Ketogenic Macro Allocation?
A ketogenic-style macro allocation is typically very low in carbohydrate and high in fat. This calculator uses a fixed planning pattern rather than claiming a universal optimal ratio.
Formula / Method Used
Planning preset: 20% protein, 5% carbohydrate, 75% fat. Grams use 4 kcal/g for protein/carbohydrate and 9 kcal/g for fat.
