My activity level is set at 8. Im 6'3 213 lbs 42 Male. Garmin says I burn 2350 calories per day.
I just logged a 15 minute walk it shows 100 calories burned. But I can go for a 3 hour walk in addition to a very active day and if I dont tell my watch im going for a "walk" I get 0 extra calories burnned. The day will end with me at 2350 + 100 from the logged walk.
I know years ago with a different garmin watch it was not like this. If I walked around my living room I could see the active calores go up. Now active calories only go up from logged activity.
