Atwater 4-4-9 Energy Densities & AMDR Ratio Splitting
Atwater energy factors assign 4 kcal/g to Protein, 4 kcal/g to Carbohydrates, and 9 kcal/g to Fat. On a 2,200 kcal High-Protein 35% P / 40% C / 25% F plan, daily targets equal: Protein = (2,200 × 0.35) ÷ 4 = 193 g, Carbs = (2,200 × 0.40) ÷ 4 = 220 g, and Fat = (2,200 × 0.25) ÷ 9 = 61 g, paired with ~31 g dietary fiber (14 g per 1,000 kcal).
Because our Macronutrient Calculator applies these rules automatically, you avoid manual rounding mistakes. Furthermore, users looking for weight loss macros or muscle gain macros workflows can test multiple scenarios side by side before finalizing their work.

Important Scope, Privacy & Accuracy Notes
Macro splits provide educational meal-planning targets for healthy adults rather than individualized clinical prescriptions. In particular, ketogenic or very-low-carbohydrate ratios can interact with insulin, SGLT2 inhibitors, pregnancy, or lipid disorders. Therefore, review major dietary shifts with a qualified physician or registered dietitian before changing your nutrition routine.
