STEP 1: Producing a raised expenditure (RE) of 200 Calories by walking instead of TV watching (or some similar activity).
Listed below are the (time in minutes) a {person weighing in pounds} is required to walk at [different speeds in miles per hour] to produce a RE of 200 Calories.
Walking at 2mph will be used to illustrate how the figures listed below are arrived at and also to correct one error (for which apologies are presented here!).
Since:
(a) Walking at 2 mph uses 0.0188 Cal per minute per pound (*Not 0.0151 Cal as stated previously*) and
(b) Watching TV uses 0.0075 Cal per minute per pound
Therefore:
REPM (raised expenditure per minute) = (0.0188 minus 0.0075) = 0.0113 Calories
Using the formula: [Time (minutes) = 200 divided by (REPM x weight in pounds)]:
For a person weighing 400 pounds:
Time = 200 divided by 4.52 [that is 0.0113 (REPM) x 400 {pounds}] = 44 minutes
You may calculate your own time (for activities of your own choice) by following the method demonstrated above.
