What is fast metabolism?

What is fast metabolism and what does it have to do with a person gaining or losing weight? Basically metabolism means the collective chemical processes that your body uses in order to convert the food that you eat into energy that the body can use to function. By eating, you ingest a certain number of calories and those are then broken down. The basal metabolic rate (BMR) is a term that is often used when discussing issues concerning weight loss or weight gain and refers to the rate at which your body breaks down food. This rate is measured at the time that the body is not engaging in physical activity (is at rest) and therefore measures the amount of energy that your body is using in order to sustain the basic life functions (things such as breathing and your internal organs such as the lungs, heart and others). A fast metabolism refers to your body breaking down food at a fast rate.

The Difference Between BMR And Maintenance Calories

Many people wrongly assume that the BMR = maintenance calories. That is not so. BMR just means the amount of calories that your body needs just to function, that means to sustain all the vital organs like the heart and the basic activities like breathing. Most people, besides breathing and staying at rest, also do other things during the day, like walking and sometimes even being active. đŸ™‚ All these activities require a greater expenditure of calories than the BMR. So in order to gain weight you need to find what your MAINTENANCE calories are. Maintenance calories are your BMR calories + the amount of calories that you expend throughout the day on going around your daily functions (for example walking around or doing sports). You should then eat more calories than your maintenance calories. For people that are trying to lose weight, they should calculate their BMR and their maintenance calories and should eat less calories than their maintenance calories, but still more than their BMR.
