About how many kcalories would someone spend just resting for an entire 24 hour period?

Resting can be a lot of things but i'm going to assume most of it is sitting.

sitting burns an estimated 75 calories per hour, but depends on your body composition, weight and metabolism.

To determine the number of calories burned in 24 hours of sitting, you need to multiply those 75 calories by the number of hours.

24 x 75 = 1800

You would burn 1800 calories.
