Active vs resting calories on Apple Watch

Your Move ring shows only part of what you burn. Here is what active and resting energy mean in Apple Health, how to see your total, and why the total is the number that matters for eating.

Two numbers, one burn

Apple Health records calories in two separate fields all day.

• Resting energy is the Watch's estimate of your basal metabolism, the calories your body spends staying alive. It is based on the height, weight, age and sex in your Health profile and accrues steadily, around 50 to 85 kcal an hour for most adults.
• Active energy is everything above resting: walking, workouts, chores, fidgeting. The Watch estimates it from your heart rate, arm motion and step count. This is the number on your Move ring.

Total calories burned for the day is simply the two added together. A 500 kcal Move ring on a 1,700 kcal resting day is a 2,200 kcal total.

Why the Move ring reads low

The Fitness app is built around activity, so it headlines active energy and buries resting energy in Health under Browse, Activity, Resting Energy. People compare a 480 kcal Move total to a TDEE calculator saying 2,400 and assume the Watch is broken. It is not. They are looking at half the number.

How to see your total burn

1. Open the Health app, tap Browse, then Activity. Resting Energy and Active Energy are separate rows; add them for today.
2. Or use an app that does the addition and keeps the history. Total Calories shows the combined number on your iPhone, as an Apple Watch complication and in a home or lock screen widget, with the active and resting split underneath.

How accurate is it?

Independent tests put Apple Watch active energy among the better wrist trackers, typically within 10 to 20% for walking and running and less reliable for cycling, strength work and anything that keeps your wrist still. Resting energy is a formula, so it carries the same limits as any BMR calculator. The daily total is still far closer to your real burn than a static TDEE estimate, because it includes what you actually did.

Making the number useful

• Keep your Health profile weight current. Resting energy is computed from it.
• Wear the Watch all day, including outside workouts, so active energy captures steps and chores.
• Average 7 or more days. Any single day is noisy; the average is your working total daily energy expenditure.
• If you log food in an app that writes to Apple Health, burn minus intake gives you a net deficit for the day without any manual math.

Common questions

Does Apple Watch count resting calories?

Yes. Resting energy is recorded in Apple Health all day, but the Fitness app's Move ring only shows active energy. Add the two for your total burn.

Why does my Apple Watch say I burned only 400 calories?

That is the active half. Your resting energy, usually 1,200 to 2,000 kcal, is tracked separately in the Health app. Your real daily total is the sum.

Can I see total calories burned on my Apple Watch face?

Not with Apple's built-in complications, which show the Move ring only. Total Calories adds a complication and widgets that show active plus resting energy as one number.
