How the macro calculator works

Calories come from your maintenance (Mifflin-St Jeor) adjusted for your goal: 500 under to lose, 300 over to build.

Protein is set per kg of body weight: 1.6 g for balanced, 2.2 g for high protein. For a higher BMI we use a reference weight so the number stays realistic.

Fat is 25-30% of calories (or carbs are 20% on lower carb), and the last macro fills what is left. Fat never drops under 20%.

Frequently asked questions

What are macros?

Macros are the three nutrients that carry calories: protein (4 cal per g), carbs (4 cal per g) and fat (9 cal per g).

Which macro split is best for weight loss?

The one you can stick with. Total calories drive weight loss. Higher protein helps you stay full and keep muscle.

How do I hit my macros eating out?

Look for a protein-forward main and adjust sides. Pleit picks takeout orders that match your macros.
