Metabolism gets blamed when people put on weight or have trouble losing weight, but you can learn how to speed up your metabolism. Increasing your metabolism can help you burn calories, replace fat with muscle and give you more energy. The key to increasing your metabolism is understanding what it is.
Metabolism is a combination of physical and chemical processes called anabolism and catabolism. Anabolism is the constructive phase of metabolism in which body cells synthesize protoplasm for growth and repair. Catabolism is the destructive phase of metabolism in which complex substances are broken down into simpler compounds producing energy which is essential for the proper functioning of body cells. Together, these processes distribute nutrients which are absorbed into the blood after digestion.
Three factors determine your metabolic rate, which is the amount of calories your body uses every day. The basal metabolic rate (BMR) is the rate your body uses energy for vital body processes. The rate you burn energy during physical activity and the rate you use energy during digestion of food are the two other factors involved in your total metabolic rate. To improve your metabolic efficiency you only need to alter what you eat and what you do a little bit to experience a difference in how you look and feel.
