Your Body's Efficiency
　　Have you ever wondered why, for so many people, weight gain seems to be a fact of life It's because the human body is way too efficient! It just does not take that much energy to maintain the human body at rest; and when exercising, the human body is amazingly frugal when it comes to turning food into motion.
　　At rest, the human body burns only about 12 calories per pound of body weight per day (26 calories per kilogram). That means that if you weigh 150 pounds (68kg), your body uses only about : 150 x 12 = 1,800 calories per day.
　　Twelve calories per pound per day is a rough estimate.
　　Those 1,800 calories are used to do everything you need to stay alive: 　　They keep your heart beating and lungs breathing.
　　They keep your internal organs operating properly.
　　They keep your brain running.
　　They keep your body warm.
　　In motion, the human body also uses energy very efficiently. For example, a person running a marathon (26 miles or 42km) bums only about 2,600 calories. In other words, you bum only about 100 calories per mile (about 62 calories per km) when you are running.
Taking Calories In
　　The 1,800 calories that a typical person at rest needs per day is just not that many. Convenient food often takes the lead in our daily diets. In a typical day someone might consume something like this:
　　You might have two Pop-Tarts for breakfast, then hit Pizza Hut for lunch, grab some Snack Well's and a cola for a snack, head for McDonald's for dinner, and top it off with some potato chips while watching TV.
　　You can see how the number of calories coming in can easily reach 3,000, 4,000 or 5,000 per day without any effort at all. That's the problem.
　　Your body, it turns out, is extremely efficient at capturing and storing excess calories. Whenever your body finds that it has excess calories on hand, it converts them into fat and saves them for a rainy day. It only takes 3,5000excess calories to create 1 pound of new fat on your body.
The Idea Behind Dieting
　　To lose 1 pound of fat, what you have to do is to burn off 3,500 calories. That is, over a period of time, you have to consume 3,500 calories less than your body needs. There are several ways you can create that deficit. If you assume that you weigh 150 pounds and that your body at rest needs 1,800 calories per day ( 150 x 12 = 1,800) to live.
