For example one burns about 200 calories while taking a walk.
Who figured that out and how?

Fitness trackers like fitbits basically take the basal metabilic rate which is the optimal calory expendature to keep everything running smoothly, and estimates it together with heart rate and activity level.. so most of it runs off the data you put into it so thats for instance why your fitness watch just assumes you will burn like 1300-1800 calories a day. As that’s kinda whats to be expected as a baseline of burning just to keep your body running.. if your watch can track blood oxygen. I.e vo2 max the values tend to be more accurate too
Its not perfect for instance some trackers may be up to 30%-50% off… for instance they overestimate burning of calories when walking. Some underestimate it Sounds like a lot but others are much worse. At higher intensity workouts most fitness trackers formulas tend to be better for instance both garmin and fitbit have been able to boast an accuracy within like 4% of the most probable true value. So your fitness tracker may sometimes overestimate it because it expects better metabolic health.
