SCIENTIFIC FORMULA & METHODOLOGY
Caloric Equivalent Macro Standard
Protein = 4 kcal/gram | Carbohydrates = 4 kcal/gram | Fats = 9 kcal/gram Balanced Split: 30% Protein / 40% Carbs / 30% Fat Low Carb / Cut: 40% Protein / 30% Carbs / 30% Fat
Every gram of protein and carbohydrate provides 4 calories, while dietary fat provides 9 calories per gram. The calculator converts percentage target splits into precise daily gram recommendations.
Clinical Limitations & Considerations
Macro needs vary according to sport, metabolic health, and personal tolerance. Individuals with insulin resistance may benefit from lower carbohydrate ratios, while endurance athletes require higher carbohydrate availability.
