    Metabolic testing provides accurate measurement of oxygen consumption and carbon dioxide production by the body at rest and during exercise. It is very useful for patients who need to lose body weight. Combined with body composition, the results can help a clinical exercise physiologist to plan a personal exercise program that is best for you.

    Many inherited metabolic disorders are diagnosed during routine tests that are done as soon as a baby is born. These tests usually include tissue samples and blood tests that doctors use to look for abnormalities in certain enzymes. Certain metabolic disorders can be diagnosed even earlier using tests like amniocentesis, which is done while a fetus is still in the womb. Unfortunately, diagnosing a metabolic disorder during childhood or adulthood can be more difficult because many of the symptoms are similar to those of other conditions. Non-inherited metabolic disorders, like type 2 diabetes, may be diagnosed by an examination of symptoms and a blood test.

    Every function of every organ in the body relies on the energy provided by the metabolism of calories. How much energy you need on any given day depends on what you are doing, what you ate, and the state of your health. The basal metabolic rate (BMR) refers to the minimal amount of calories you need to live. Some people need only 1,200 calories, while professional athletes may need 2,000 or more.

    Your basal metabolic rate (BMR) is the number of calories your body burns daily without your having to do anything. Your body uses around 75 percent of the calories you eat each day just to maintain life and perform basic functions. You expend energy just to breathe, build new red and white blood cells, tone your muscles, pump blood throughout the body, think, raise or lower your body temperature -- even while you're sleeping. Any activity you do in addition to these natural functions also requires fuel in the form of calories. If you eat more calories than your body metabolism needs daily, you will gain weight. There are 3,500 calories in every pound of body fat. That means that if you eat 500 calories more per day than your body needs, you will gain one pound every week.
