Dr. Islam replied: "Metabolism is essentially the speed at which our body's motor is running. The speed at which our body burns calories is called the metabolic rate. It's how fast your "motor" is running when you're still in a reclined position or sleeping. About 60-75% of energy is expended by the body at rest in such activities. The metabolism is based on the number of calories we burn throughout the day. Our body constantly burns calories to keep us going whether we are eating, sleeping, cleaning etc. People with a lower percentage of body fat (i.e. muscular) have a higher metabolism than others that are less muscular because muscle uses more calories to maintain itself than fat. Some people have a slower metabolic rate and have a harder time staying slim. Younger persons have higher (faster) metabolism because of the increased activity of cells. A slow metabolism actually causes to store fat. The slower the metabolic rate, the greater the weight gains. How to build muscles to improve metabolism? What type of exercise is ideal that speed up metabolism so that you burn calories even at rest or sleep? There are simple exercises that speed up the metabolism. Causes for Low Metabolism * Fasting * A low calorie diet * Snacking throughout the day on high sugared foods (candy, colas, cakes, gum). * Eating or drinking too much sugar containing foods. * Lack of physical activity. * Underactive thyroid. Metabolism Boosters There are some natural metabolism boosters (natural foods) that improves your metabolism. Do not take over the counter pills containing animal thyroid extract that claim to boost up metabolism. These products may have side effects as diarrhea, increased heart rate, excessive sweating, nervousness, tremors, bulging eyes, etc. How to Improve (Speed up) Metabolism * Do not skip any meals * Exercise daily * Build your muscles * Avoid alcohol, sugar, and fastings *Drink 8-10 glasses of water daily. *Eat foods with high nutrition values"
