How Many Miles Per Gallon Do YOU
your engine - your body - with one of the best energy-supplying snacks of all:
a classic peanut butter and jelly sandwich on whole wheat bread. Fill 'er up
with a tall glass of milk, and gentlepersons, start your engines!!!
Food is to your body as gas is to a car's engine. Everything we eat and drink, except water, contains
calories. Calories are the source of our body's energy, just as gasoline provides
energy for a car to run.
you would never, ever drink gasoline - it's poisonous and can kill you. But did
you know that a gallon of gasoline contains about 31,000 calories? That would
be enough to keep a medium-sized person going for more than two weeks!
bodies are so efficient that if humans could drink gasoline instead of eating
pizza and burgers for calories, we could run more than 300 miles on just one
gallon of gasoline!
eating food is SO much tastier. And our bodies do a great job of extracting the
energy we need from the foods and drinks we consume. Our bodies are the
ultimate hybrid engines!
with vehicles, different sizes of people, doing different things with their
bodies, will have significantly different fuel needs. A lean athlete who exercises
hard, two hours a day, will be able to consume more calories than a person of
the same weight who is basically sedentary, without gaining weight. The human
body at rest uses just 12 calories per pound per day. The more you move around,
the more calories you burn - and the more you can eat.
