It is important to understand how your body gains weight in order to learn
how you can lose weight.
Human body is too efficient than any machine you can find
in the world. The body does not take as much energy as we think. While
at rest (such as watching TV on the sofa), human body burns only about
12 calories per pound of body weight per day (26 calories per kilogram).
For example if you weigh 150 pounds (68 kg), your body uses only about:
150 X 12 = 1,800 calories per day
 |
These
1,800 calories are used to do everything you need to stay alive. That
is: to keep your heart beating and your lungs breathing; to keep your
internal organs operating properly; to keep your brain running, and
etc. Even In motion, the human body also uses energy very efficiently.
For example, a person running a marathon (26 miles or 42 km) burns
only about 2,600 calories. In other words, you burn only about 100
calories per mile (about 62 calories per km) when you are running.
YET if 1800 calories is what we need per day is really not that many.
For example, a meat at Mcdonald can add up to almost a whole day's
worth of calories. just one meal provides almost 1,600 calories you
needduring a day. If you get a McFlurry with it for dessert, you'll
get 630 more calories, so you are already consuming almost 2,200 calories
just at this one meal. |
| Therefore,
as you can imagine, in a typical day, you can easily reach 3,000,
4,000 or 5,000 calories without any effort at all. So what does your
body do when you intake excess calories? YES, your body turns them
into FAT. It only takes 3,500 excess calories to create 1 pound of
new fat on your body. If you are taking in just 500 extra calories
per day, then you are gaining a pound of fat per week (500 calories
x 7 days in a week = 3,500 calories/week). Since it is easy to get
500 calories from just one ice cream cone or a few cookies, you can
see that weight gain is completely effortless in today's society. |
