Metabolic rate and metabolism -

After we eat food, the digestive system uses enzymes to:. The body can use sugar, amino acids, and fatty acids as energy sources when needed. These compounds are absorbed into the blood, which carries them to the cells.

After they enter the cells, other enzymes act to speed up or regulate the chemical reactions involved with "metabolizing" these compounds. During these processes, the energy from these compounds can be released for use by the body or stored in body tissues, especially the liver, muscles , and body fat.

Anabolism uh-NAB-uh-liz-um , or constructive metabolism, is all about building and storing. It supports the growth of new cells, the maintenance of body tissues, and the storage of energy for future use.

In anabolism, small molecules change into larger, more complex molecules of carbohydrates, protein, and fat. Catabolism kuh-TAB-uh-liz-um , or destructive metabolism, is the process that produces the energy needed for all activity in the cells.

Cells break down large molecules mostly carbs and fats to release energy. This provides fuel for anabolism, heats the body, and enables the muscles to contract and the body to move.

As complex chemical units break down into more simple substances, the body releases the waste products through the skin, kidneys, lungs, and intestines. Several hormones of the endocrine system help control the rate and direction of metabolism. Thyroxine, a hormone made and released by the thyroid gland, plays a key role in determining how fast or slow the chemical reactions of metabolism go in a person's body.

Another gland, the pancreas , secretes hormones that help determine whether the body's main metabolic activity at any one time are anabolic an-uh-BOL-ik or catabolic kat-uh-BOL-ik. For example, more anabolic activity usually happens after you eat a meal. It is always best to speak with a doctor before adjusting the diet or making changes to an exercise routine.

Vitamins and minerals that boost metabolism. Medically reviewed by Debra Rose Wilson, Ph. Myths and facts about metabolism. As epigeneticist John Speakman wrote in a analysis , one issue with the hypothesis is that not everybody in modern society is fat:.

We would all have the thrifty alleles, and in modern society we would all be obese. Yet clearly we are not. If famine provided a strong selective force for the spread of thrifty alleles, it is pertinent to ask how so many people managed to avoid inheriting these alleles.

And, Rosenbaum added, "The evolution of our genetic predisposition to store fat is quite complex. It involves a frequently changing environment, interactions of specific genes with that environment, and even interactions between genes.

Researchers are also trying to better understand metabolic syndrome — the name given to a set of conditions including increased blood pressure, high blood sugar, a large waistline, and abnormal cholesterol or triglyceride levels. When people have several of these health issues, they're at an increased risk of chronic health issues, including heart disease, stroke, and diabetes.

Again, how this works and why it affects some people more than others remains unclear. So weight loss is possible. For any would-be weight loser, Rosenbaum said the key is finding lifestyle changes you can stick to over a long period of time, and viewing those as changes needed to keep a disease — obesity — under control.

You can read more advice from top weight loss doctors here. He pointed to the National Weight Control Registry, a study that has parsed the traits, habits, and behaviors of adults who have lost at least 30 pounds and kept it off for a minimum of one year — as an example of how they do that.

The registry currently has more than 10, members enrolled in the study, and these folks respond to annual questionnaires about how they've managed to keep their weight down. The people who have had success in losing weight have a few things in common: They weigh themselves at least once a week.

They exercise regularly at varying degrees of intensity, with the most common exercise being walking. They restrict their calorie intake , stay away from high-fat foods, and watch their portion sizes.

They also tend to eat breakfast. But there's a ton of diversity as to what makes up their meals. So there is no "best" diet or fad diet that did the trick. And they count calories. because I'm lazy and gluttonous. Researchers are looking at variety of animal models to see what they can tell us about the mysteries of the human metabolism.

Metabolism or metabolic rate is defined as the series of chemical reactions in a living organism that create and break down energy necessary for life. More simply, it's the rate at which your body expends energy or burns calories. Metabolism is partly genetic and largely outside of one's control.
