Macro Calculator

How much protein, carbohydrates and fat do you actually need each day? This macro calculator computes your daily calorie target (TDEE) via the Mifflin-St Jeor formula and splits them into optimal macronutrients based on your diet style — standard, low carb, high protein or keto.

Come funziona il Macro Calculator

First your Basal Metabolic Rate (BMR) is calculated using the Mifflin-St Jeor formula: BMR = 10 × weight(kg) + 6.25 × height(cm) − 5 × age + 5 (male) / −161 (female). Multiplied by the PAL factor (activity level), this gives your TDEE (Total Daily Energy Expenditure). Your goal adjusts the target: lose weight −500 kcal, maintain ±0, bulk +300 kcal.

Macros are distributed by diet style: Standard: protein 2.0 g/kg, fat 0.9 g/kg, carbs = remainder. Low Carb: protein 2.2 g/kg, fat 1.2 g/kg, carbs = remainder. High Protein: protein 2.5 g/kg, fat 0.8 g/kg, carbs = remainder. Keto: protein 1.8 g/kg, 75% of calories from fat, carbs capped at 5%.

What are macros and why do they matter?
Macronutrients (macros) are the three main energy sources: protein (4 kcal/g), carbohydrates (4 kcal/g) and fat (9 kcal/g). The right ratio influences muscle gain, fat loss, satiety and athletic performance. Counting only calories ignores quality — tracking macros lets you optimise body composition with precision.
What is the difference between standard, low carb, high protein and keto?
Standard (balanced): roughly 30% protein, 35% carbs, 35% fat. Low carb: under 25% carbs, higher fat. High protein: over 35% protein — ideal for muscle building and satiety. Keto: under 5% carbs (below 25–30 g/day), 70–75% fat, body burns ketones instead of glucose.
How accurate is the macro calculator?
The Mifflin-St Jeor formula is considered the most accurate BMR estimate for normal-weight individuals (±10% deviation). For bodybuilders with high muscle mass, actual needs may be higher. Track for 2–3 weeks and adjust calories based on your real weight change.
