Given the relatively modest number of calories burned by anything but the most vigorous activities, why can people consume over 2,000 kilocalories a day, yet maintain a healthy body weight?
a. They can't, and this has led to a problem of obesity in the United States.
b. People really should exercise vigorously for one to two hours per day.
c. Most of the energy consumed in food is spent maintaining the body's functions, so only a fraction of food energy needs to be burned in exercise.
d. Not all calories are created equal, so a person who consumes 2,000 kilocalories of sugar- and fat-laden processed food will gain weight, while a person who consumes 2,000 calories of nonprocessed, low-carbohydrate food will not.
