Your body naturally at rest burns/needs calories all day to run, and the walking/exercise is in
addition to those such calories. Goes by your weight and height. My body naturally burns almost 1900 calories every 24 hours at rest to function, so if I burn the example of 1000 calories from the walking/exercise each day I can consume right at 3000 calories for each day while at Disney without gaining any weight.
And it would take 3000 calories over that said 3000 I'm burning to gain 1 pound. It takes an excess of 3000 extra calories added to your diet to gain 1 pound in a day or over a certain time period like a week.
I know my facts from doing research and talking to specialist in this field. I also do not ride many rides that would add much to the tracker and can easily do over those 10 miles a day etc. So yes your info is correct but your forgetting about adding the calories each individual persons body burns naturally to get through a day even if sitting all day by their height and weight. A nutritionist can explain this.
