Calories Burned Eating Formula
The basic calculator uses body weight, meal time, and eating style. If you enter kilograms or hours, the calculator converts them automatically.
C = BW * M * F
Variables:
- C = calories burned
- BW = body weight in pounds
- M = time spent eating in minutes
- F = eating-style factor
Use the following eating-style factors in the basic formula:
- 0.0119 for sitting and eating
- 0.0143 for standing and eating
- 0.0159 for light movement while eating
The advanced tab uses your own calorie rate per minute:
C = R * M
R is calories burned per minute.
