The IIFYM Macro Split Calculator estimates calories and macronutrients from body measurements, activity, and a selected goal. IIFYM means fitting planned protein, carbohydrate, and fat within an overall calorie target.
Interpretation
The result is a planning range, not a guarantee of fat loss, muscle gain, or health. Food quality, fibre, micronutrients, allergies, and medical conditions remain important.
Questions
Does IIFYM mean food quality does not matter?
No. Macro targets describe energy and macronutrients; they do not replace a balanced diet.
Are the calorie targets exact?
No. They are estimates based on population equations and selected activity assumptions.
