Macro calculation starts with your TDEE (Total Daily Energy Expenditure) adjusted for your goal — a calorie deficit for fat loss, surplus for muscle gain, or maintenance for body recomposition. Protein is set first as grams per pound (or kg) of bodyweight, since it's the most critical macro for preserving muscle during a cut and building muscle during a bulk. Fat is set at a minimum threshold for hormone health. Remaining calories fill carbohydrates.
Macro Calculation Order
1. Set Calories
TDEE ± goal adjustment
−500 cal/day = ~1 lb/week loss
2. Set Protein
0.7–1g per lb bodyweight
non-negotiable, set first
3. Fill Carbs & Fat
Remaining calories

Tracking macros is most useful in the first 4–8 weeks — it builds intuition about portion sizes and food composition that stays with you even after you stop tracking. Use a food scale and a tracking app like MyFitnessPal or Cronometer to verify your estimates. Most people are surprised to find they eat significantly more (or less) than they thought. After a few weeks, many people can hit their targets without tracking every meal.
For active individuals doing strength training, 0.7–1.0 grams per pound of body weight (1.6–2.2 g/kg) is recommended. Sedentary adults need less — around 0.36 g/lb (0.8 g/kg). Higher protein (up to 1g/lb) helps preserve muscle during weight loss and supports muscle building. Protein has 4 calories per gram.
IIFYM is a flexible dieting approach where you track macronutrient totals (protein, carbs, fat) rather than restricting specific foods. As long as you hit your daily macro targets, you can eat any foods you choose. It emphasizes flexibility and sustainability over rigid meal plans.
For weight loss, a higher protein split (30–40% of calories) helps preserve muscle and keeps you satiated. A common weight loss macro split is 35% protein / 35% carbs / 30% fat. Low-carb approaches (20–30% carbs) also work well for some people. The best split is one you can adhere to consistently.
Protein: 4 calories per gram. Carbohydrates: 4 calories per gram. Fat: 9 calories per gram. Alcohol: 7 calories per gram (not tracked as a macro but adds calories). This is why fat-heavy diets can be calorically dense — fat has more than twice the calories per gram compared to protein or carbs.
