Weight Management!!

Have you ever wondered why, for so many people (and especially for anyone older than 30 years old), 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 (for example, while sitting and watching television), 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 (68 kg), your body uses only about:
150 X 12 = 1,800 calories per day

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.

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 to fat and saves them for a rainy day. 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. Food is just too easy to find.

THE IDEA BEHIND DIETING

Let's imagine that you are overweight and you would like to lose several excess pounds. To lose 1 pound of fat, what you have to do is 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 * 12 = 1,800) to live, here are several examples (some realistic, some not):

· You could lie in bed and starve yourself. Since you are lying in bed, you are consuming 1,800 calories per day. Since you are starving yourself, you are taking in no calories. That means that, every day, you create a deficit of 1,800 calories and, approximately every two days, you will lose 1 pound of body weight.

· You could consume fewer calories than your body needs. For example, you might choose to consume 1,500 calories per day rather than the required 1,800 by controlling what you eat. That creates a 300-calorie deficit every day. That means that approximately every 12 days, you will lose 1 pound of weight (12 days x 300 calories = 3,600 calories).

· You could consume 1,800 calories per day and then choose to jog 2 miles (3.2 km) every day. The jogging would burn about 200 calories per day, and over the course of 18 days you would burn about 1 pound of body weight (18 days x 200 calories = 3,600 calories).

· You could consume 2,500 calories per day and run 10 miles per day. You will burn 1,800 calories per day at rest and then 1,000 calories per day running, for a total of 2,800 calories. You are consuming 300 calories fewer than you need, so you would lose a pound every 12 days or so (300 calories x 12 days = 3,600 calories).

As you can see from these examples, the only way to lose fat is to consume fewer calories per day than your body needs. For every 3,500 calories that your body takes from its fat reserves, you lose 1 pound (0.45 kg) of body fat. You can create the deficit either by monitoring and restricting your intake of calories, or by exercising, or both.

BUILDING A SUSTAINABLE DIET

The first step is to start counting the calories that you consume in a day so that you become conscious of two things:

· You need to understand exactly how many calories you are eating on a "normal" day.

· You need to realize where each calorie comes from -- you need to build a calorie database in your brain so that you know, whenever you eat something, just how many calories it is supplying.

The second step is to figure out how many calories you need in a day. You can use the "12 grams per pound" rule, or you can get more precise by looking at our Calorie Chart.

The third step is to compare the two numbers -- You may be startled by the difference between the "number of calories you need" and "the number of calories that you take in" in a day. That is where the extra pounds are coming from.

The fourth step is to figure out how to bring the two numbers in line. What you will soon realize is that 1,600 or 1,800 or 2,000 calories per day just isn't that many. You have to watch and count everything you eat and drink every day and stick to your daily limit.

The fifth step might be to add exercise to the mix so that you can raise the number of calories you can consume per day.

Good Luck To All Those Who Are Trying To Loose Weight.
