Converts a calorie target and selected goal into estimated daily protein, carbohydrate and fat targets.
The calculator applies the goal-specific macronutrient percentages configured in the tool and converts calories from each macronutrient into grams. The calculation uses daily calories and nutrition goal.
Macro ratios are not one-size-fits-all and may need adjustment for training, medical conditions, food preferences and clinician advice. Use the number as an estimate and consider professional advice when the result may affect health, treatment, pregnancy, nutrition, exercise safety or another important decision.
