Macronutrient Calculation Formula:
From: | To: |
This calculator determines optimal macronutrient distribution (protein, fat, and carbohydrates) for fat loss based on your weight and daily calorie intake. It follows evidence-based ratios that support fat loss while preserving muscle mass.
The calculator uses the following formulas:
Where:
Explanation: This approach prioritizes protein intake to preserve muscle mass during calorie deficit, provides adequate fat for hormone production, and fills remaining calories with carbohydrates for energy.
Details: Proper macronutrient distribution is crucial for effective fat loss. Adequate protein prevents muscle loss, sufficient fat supports hormone function, and controlled carbohydrates help manage energy levels and hunger.
Tips: Enter your current weight in kg and your target daily calorie intake (typically 300-500 kcal below maintenance for fat loss). The calculator will provide your recommended daily grams of protein, fat, and carbohydrates.
Q1: Why 2.0 g/kg of protein?
A: Research shows higher protein intake (1.6-2.4 g/kg) helps preserve lean mass during calorie restriction and increases satiety.
Q2: Can I adjust these ratios?
A: Yes, you can modify protein to 1.6-2.4 g/kg based on preference, and adjust fat between 20-35% of calories.
Q3: What if my carbs seem very low?
A: If carbs are below 100g/day, you may want to slightly reduce fat percentage to allow for more carbs, especially if you're active.
Q4: How often should I recalculate?
A: Recalculate every 4-6 weeks or after significant weight loss (5+ kg) to adjust for your new weight.
Q5: Are these macros suitable for everyone?
A: While generally effective, individuals with specific medical conditions or elite athletes may need customized plans.
