Macro Calculator
Macronutrient Energy Standards
Each macronutrient provides a specific amount of energy per gram. Our calculator uses these industry-standard energy density conversion rates:
1 Gram of Protein = 4 Calories
1 Gram of Carbohydrate = 4 Calories
1 Gram of Fat = 9 Calories
Calculation Method: Total Calories × Macro Ratio % ÷ Calories per Gram
Frequently Asked Questions (FAQ)
1. What are Macronutrients (Macros)?
Macronutrients are the three main nutrients your body needs in large amounts for energy: Protein (4 kcal/g), Carbohydrates (4 kcal/g), and Fats (9 kcal/g).
2. What is the best macro ratio for fat loss?
A popular macro ratio for fat loss is High Protein or Low Carb (40% Protein, 30-40% Carbs, 20-30% Fat), which preserves lean muscle mass while keeping you full in a calorie deficit.
3. How many grams of protein should I eat daily?
For active individuals and strength training, 1.6 to 2.2 grams of protein per kilogram of body weight (approx. 0.7 - 1.0g per lb) is recommended.
4. How does the Keto Macro Split work?
A standard Ketogenic split consists of 70% Fat, 25% Protein, and 5% Carbohydrates to shift your body into using fat as its primary fuel source (ketosis).
5. Do I need to weigh my food to track macros accurately?
Yes, using a digital kitchen scale to measure raw or cooked ingredients is the most reliable way to accurately hit your macro targets.
6. Should I calculate my macros based on TDEE?
Yes! Your macro targets should always stem from your Total Daily Energy Expenditure (TDEE) and specific fitness goals.
