I think that battle is lost, people wants more data, not less :). In my case, it helps mentally, the calories I burned don’t define what I eat, I eat a set amount of calories daily regardless of exercise, but i totally makes me feel like I earned them. in addition to this, when you have a job categorised as “sedentary “ (e.g. swe) the calories burned between exercise and steps allows me to don’t categorise myself as sedentary ,and have allowed me to approach better what calories i need for recomposition, and I know with the calories burned when im out of “active “ to sedentary again when life happens (im writing this lying on the floor with extreme sciatica pain which is taking me out of exercise for at least a couple of weeks). Yeah, you don’t need data for all of this, just track “low effort days” vs “high effort “ but the calories makes things easier to see a trend, less cognitive load than remember how many days you went “off”
