  Metabolism & Metabolic Syndrome
While cardiologists and diabetologists argue about definitions and criteria of the metabolic syndrome, the events are taking their own course: though the statistics remains frightening, these very criteria are already working toward practical recommendations on how to prevent and fight this “epidemic of the 21th century.
The metabolic abnormalities associated with insulin resistance have been shown to be sixfold higher in smokers than in non-smokers.
If, plus to metabolic syndrome, they had a tendency to inflammation, their odds were 66 percent, while people with the syndrome but no inflammation did not show an increased likelihood of mental health impairment at all.

 What is Metabolism and Why is it Important?
Metabolism is the amount of energy (calories) your body burns to maintain itself.
If you eat a very low-calorie diet, your metabolism will slow down in order for your body to survive (your body thinks it is starving).
Most experts agree that weight training and aerobic exercise do increase metabolism while you are exercising and after you are done.

Or it could be used to predict what would happen if you interfere with a metabolic reaction in a specific type of cell, such as a blood or heart cell.
Metabolic reactions in cells include those which convert food sources, such as fats, protein and carbohydrate into energy and to make other molecules used by the body.
Keith Frayn, professor of human metabolism at the University of Oxford, said the model would allow scientists to spot potential problems with targeting certain reactions early on in their research.

  Metabolism
Metabolism converts the fuel in the food we eat into the energy needed to power everything we do, from moving to thinking to growing.
Metabolism is a complicated chemical process, so it's not surprising that many people think of it in its simplest sense: as something that influences how easily our bodies gain or lose weight.
When the metabolism of body chemicals is blocked or defective, it can cause a buildup of toxic substances in the body or a deficiency of substances needed for normal body function, either of which can lead to serious symptoms.

That consumption is then used to calculate the basal metabolic rate, which is expressed as the number of kilocalories of energy used per kilogram of body weight, per hour.
At their active metabolic rate, hummers are only a few hours from starving to death; periods of bad weather threaten them severely even at their basal rate.
Interestingly, both birds and moths operate at similar body temperatures when hovering and feeding; the moths use metabolic heat generated by vibrating their wing muscles to raise their temperature to as high as 104 degrees F The "warm-blooded" (endothermic) birds drop their temperature during the night (when they are at rest) to conserve energy.

Metabolism (chemistry), inclusive term for the chemical reactions by which the cells of an organism transform energy, maintain their identity, and reproduce.
Anabolism, or constructive metabolism, is the process of synthesis required for the growth of new cells and the maintenance of all tissues.
Metabolism, from a thermodynamic point of view, embraces the processes by which cells chemically intercept and distribute energy as it continuously passes through the organism.

 metabolism. The Columbia Encyclopedia, Sixth Edition. 2001-05
Two subcategories of metabolism are anabolism, the building up of complex organic molecules from simpler precursors, and catabolism, the breakdown of complex substances into simpler molecules, often accompanied by the release of energy.
The basal metabolism rate is usually measured indirectly by calculation from measurements of the amounts of oxygen and carbon dioxide exchanged during breathing under certain standard conditions, i.e., complete rest in a room temperature of 68°F (20°C), 12 to 14 hours after ingestion of food.
A less cumbersome method of estimating basal metabolic rate involves the quantitative assay of the hormone thyroxine, known to regulate the body’s rate of metabolism.

 Weight Control and Metabolism
Metabolism, in this single process model, was thought of as the fire within the body that "burns" the stuff you eat, turning it into energy.
So it is not surprising that the most common analogy for metabolism, the conceptual model that has the most appeal to common sense, is of a fire in a fireplace.
What we call metabolism is in fact the result of a number of processes in the body that determine how it deals with various substances.

The idea that a low metabolic rate is always responsible for excess weight is just one of a number of misconceptions about metabolism, says researcher James Hill, Ph.D., director of the Center for Human Nutrition at the University of Colorado Health Sciences Center in Denver.
A In simple terms, metabolism is the rate at which your body breaks down the nutrients in food to produce energy, Hill explains.
Metabolism is determined by a complex set of factors.

A decreased metabolic rate is often the very reason that weight loss progress grinds to a sudden halt.
By increasing your metabolism, you are giving your body a reason to hold onto protein, so that less water is lost.
Exercise will increase the metabolism, but the trick for those trying to lose weight is to perform the right exercises for their specific body type, and not to cut too many calories too soon.

This increase in metabolism is not totally sufficient in maintaining body temperature, so wild sea otters will interrupt their rest with bouts of activity.

 Metabolism
METABOLISM is the means by which the body derives energy and synthesizes the other molecules it needs from the fats, carbohydrates and proteins we eat as food, by enzymatic reactions helped by minerals and vitamins.
Although this page is devoted to diseases caused by errors in metabolic processes, there is actually a significant level of tolerance of errors in the system: often, a mutation in one enzyme does not mean that the individual will suffer from a disease.
Many of these are inborn errors of metabolism: inherited traits that are due to a mutation in a metabolic enzyme; others involve mutations in regulatory proteins and in transport mechanisms.

Your metabolism plays a significant role in weight management: The faster your metabolism, the more calories you'll burn, and the less likely that you'll be overweight.
Muscle is more metabolically active than fat, she explains, so replacing your fat stores with lean muscle allows you to maintain your weight much more easily.
A slower metabolism is a natural part of aging, Fernstrom explains, so to maintain a stable weight, you must adjust your caloric intake and/or physical activity.
