Move calories vs. workout calories: what your watch is really counting
By Robert Robinson, founder of Neato Health · September 15, 2026 · 4 min read
Your daily burn has three parts: resting, everyday movement, and workouts. Here is what each one is, why the everyday part is bigger and more variable than the gym, and how Neato keeps a walk from being counted twice.
Fitness trackers made everyone aware of the calories they burn exercising, and in doing so they made the gym seem like the main event. It isn’t. For most people the calories burned walking to the car, cooking dinner, fidgeting in meetings and standing in line outnumber the calories burned in workouts by two or three to one. Neato tracks both, and keeps them apart, because they behave differently.
Three parts of a day’s burn
- Resting. What you burn doing nothing. The resting-burn guide covers it. Typically 60 to 75 percent of the day.
- Move calories. Everything that is movement but not a workout: steps, stairs, housework, shopping, typing, standing, fidgeting. Researchers call it NEAT, non-exercise activity thermogenesis. Typically 15 to 30 percent of the day, and the most variable part between people.
- Work calories. Deliberate exercise: the run, the lift, the class. For someone who trains four times a week for an hour, it is roughly 10 percent of a week’s burn. For someone who doesn’t, it is zero.
Apple Health lumps the second and third together as Active Energy, and reports Resting Energy separately. That is fine for a watch. It is not fine for planning, because the two active parts respond to different things.
Why everyday movement matters more than it seems
In 1999, Levine, Eberhardt and Jensen overfed 16 volunteers by 1,000 calories a day for eight weeks and measured where the calories went. Fat gain varied tenfold between people, from under a kilo to over four. The variable that explained most of the difference was not exercise, which was held constant, but NEAT: the people who resisted fat gain unconsciously moved more, by up to 700 calories a day, through posture, fidgeting and walking. The people who gained the most sat still.
Levine’s 2002 review put the range of NEAT between people at up to 2,000 calories a day for individuals of similar size, driven by occupation, environment and habit. A mail carrier and a programmer with the same resting burn can differ by more than a workout’s worth of calories every single day.
This is why Neato’s daily burn does not assume a fixed “activity multiplier” the way older calculators do. It starts from a daily-living baseline of about twice your body weight in pounds in calories, so 340 a day for a 170-pound person, and then lets your own measurements move it: Apple Health’s active energy when a watch or phone is reporting, and the scale-based calibration described in the scale guide for everyone.
How minutes become calories
When you log a workout by minutes rather than from a watch, Neato needs a rate. The rates come from the Compendium of Physical Activities, a catalog maintained since 1993 by Ainsworth and colleagues that assigns every activity a MET value: a multiple of resting burn. Sitting quietly is 1 MET. Brisk walking is about 3.8. General weightlifting is about 5. Cycling at a moderate effort is 7.5, and running at a 10-minute-mile pace is about 9. Calories per minute are METs times your body weight in kilograms divided by 60, roughly. A 75 kg person lifting for 45 minutes at 5 METs burns about 280 calories.
The intensity words in Neato, “easy” and “hard,” nudge the MET value up or down within the Compendium’s range for that activity. They are honest approximations. A watch with a heart-rate sensor does better for cardio; for lifting, neither method is precise, because lifting is intermittent and the watch mostly sees the rests.
Not counting the same walk twice
This is the part most apps get wrong. If your daily burn already includes an allowance for everyday movement, and you then add a 30-minute walk as a workout, the walk has been counted twice: once in the baseline and once as exercise. Eating back both is how people gain weight on a tracker.
Neato counts a logged workout as replacing the resting and everyday burn for those minutes, not adding to it. The Work calories shown for a session are the calories above what you would have burned anyway during that time. And when a watch reports active energy for the whole day, the logged workouts are taken out of the daily-living estimate so the total is the same whichever way you look at it.
What to do with this
The practical conclusion from Levine’s work is that the cheapest calories to burn are the ones that don’t feel like exercise. A standing desk, taking calls on foot, parking far away and carrying the groceries add up to more than a gym session for most people, and they don’t leave you hungrier the way a hard run does. Neato’s Exercise tab shows Move calories alongside Work calories so that a day with no workout but a lot of walking gets the credit it deserves, and so that a rest day that was also a couch day is visible for what it was.
Workouts still matter, but mostly for reasons other than calories: they protect muscle in a deficit, they build it in a surplus, and they are the strongest lever on health that has nothing to do with the scale. The exercise guide covers how much.
