The calorie & macro calculator
The calculator sets your daily calorie and macro targets from your body stats and your goal, then hands them straight to Fuel.
🎬 Video walkthrough coming soon.
Find your numbers
- Open the Fuel tab and tap Calorie & Macro Calculator at the bottom.
- Under About You, pick male or female and enter your Age, Weight (lb), and Height (in).
- Choose an Activity Level: Sedentary, Light, Moderate, or Very Active. If you're unsure, pick the lower one.
- Pick a Goal, anywhere from -20% (aggressive cut) to +10% (lean bulk), or Maintain.
- Set your Protein & Macro Split: how much protein you want, and whether to lean toward more carbs or more fats.
Save your targets
The Your Targets section shows your daily calories, your maintenance estimate, and your protein, carbs, and fats. Use the per-meal selector to see how that breaks down across your meals. Tap Save as My Targets and those numbers become the Goal row back in Fuel.
It's a starting point, not gospel. The calculator uses the Mifflin-St Jeor formula, a well-established estimate. Run with it for a couple of weeks, watch your weight trend, and adjust from there.
