An Insight on Basal Metabolic Rate |
Posted: July 7, 2018 |
In general terms Basal Metabolic Rate is the amount of calories your body need to function while at rest. BMR can be indirectly said as the metabolism of the body and this is the reason when there is an increase in the metabolic weight the BMR also increases. Hence prior moving ahead to elaborate more about BMR it would be better to illustrate about metabolism to make the things more clear. The definition of metabolism if taken from the text books says that it is the process of converting food into energy. During this complex biochemical process calories from the food combines with oxygen and releases energy that is utilized to carry out numerous body functions. The rate at which calories are burn depends directly on the metabolism rate of the individual and this is the reason you often hear overweight people blaming their metabolism. In fact metabolism and weight are closely related but slow metabolism is not the real reason behind putting on a lot of weight. Different factors like mentioned below are also the factors that determine the basal metabolism rate of an individual:
Beside this there are two other factors which decide how many calories are burn by the body each day. Thermogenesis- It is a combined definition of the process where calories are burn due to digestion, absorbing, transporting and storing the food. Physical activity- The amount of activities an individual does like walking, playing, jogging, running burns the rest of the calories. Now coming back to BMR why it’s important to know BMR The BMR lets an individual achieve fitness goal because it shows the number of calories the body needs to stay alive and function. Thus knowing BMR can help people figure out how many calories they are consuming daily. When people know almost the exact figure of the calorie they are taking daily they can plan the diet well. An individual can very easily find out if he/she is taking few calories or consuming way more than the required. BMR simplifies the things for people who have no idea what is happening with their body even when they are sticking to a strict diet and working out regularly. How to calculate BMR There are many ways to know the BMR of an individual but the most accurate way to measure it accurately is by having a lab test. Beside this there are many online bmr calculator that and individual can use to know about his/her basal metabolic rate. Offline method of finding out the BMR can be done with the help of Harris-Benedict Equation which is as follows: For Men: (6.25 multiplied by body weight in pounds) + (12.7 multiplied by height in inches) – (6.76 multiplied by age) + 66 For Women: (4.35 multiplied by body weight in pounds) + (4.7 multiplied by height in inches) – (4.68 multiplied by age) + 655 One can also find out the total daily energy expenditure by including the activity factor in the same Harris-Benedict equation that provides the overall calorie expenditure by multiplying the BMR number by:
