MYTH: Exercise makes one lose weight.
TRUTH: Guyton, in Textbook of Medical Physiology, gives the Calorie
expenditures of various levels of activity as:
Activity Calories per hour
Sleeping 65
Awake lying still 77
Sitting at rest 100
Standing relaxed 105
Dressing/undressing 118
Typing rapidly 140
"Light" exercise 170
Walking slowly (2.6 miles per hour) 200
Carpentry, industrial painting 240
"Active" exercise 290
"Severe" exercise 450
Sawing wood 480
Swimming 500
Running (5.3 miles per hour) 570
"Very severe" exercise 600
Walking very fast (5.3 miles per hour) 650
Walking up stairs 1100
If we take our normal daily activity as equivalent to typing, the
increase in activity for running is 570 - 140 = 430 Calories per hour.
Since animal "fat" has about 3500 Calories per pound, one would have to
run for 3500/430 = 8.1 hours to "burn off" a pound of fat.
So, to "burn off" a pound of "fat", one would have to RUN 5.3 miles/hr
x 8.1 hr = 43 MILES!!
Conclusion: one CAN NOT lose weight by exercise. That is why we
see overweight aerobics instructors.
