1. Calculate your TDEE (Total Daily Energy Expenditure)

Your TDEE is the total energy you burn in a day, accounting for your activity level. It’s your starting point for any goal.

<aside> ✅

You can use this calculator to calculate your TDEE.

Or do it manually if you prefer:

Base formula (Mifflin-St Jeor):

Men:

BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) + 5

Women:

BMR = (10 × weight in kg) + (6.25 × height in cm) − (5 × age) − 161

Your BMR is what you burn at complete rest. Now multiply by your activity level:

Activity Level Multiplier
Sedentary (little or no exercise) × 1.2
Lightly active (1–3 days/week) × 1.375
Moderately active (3–5 days/week) × 1.55
Very active (6–7 days/week) × 1.725
Extremely active (2 sessions/day) × 1.9

TDEE = BMR × multiplier

2. Adjust for your goal

Goal Caloric adjustment
Lose fat TDEE − 300 to 500 kcal
Maintain TDEE
Build muscle TDEE + 200 to 400 kcal

<aside> ℹ️

A deficit above 500 kcal/day can cause muscle loss. A surplus above 500 kcal/day tends to lead to excess fat gain. Go slow and steady.

3. Split your macros

Once you have your calorie target, distribute them like this (general guidance for active people):

Macro Recommended range Calories per gram
Protein 1.6–2.2g per kg of body weight 4 kcal/g
Carbohydrates 40–50% of total calories 4 kcal/g
Fats 25–35% of total calories 9 kcal/g

<aside> 💡

Macros split recommendations:

For strength training, prioritize protein intake, keep fats moderate, and use carbohydrates as your main performance driver.
