What is BMR?
BMR stands for Basal metabolic rate, which are the minimum calories we require to live. It is influenced by lean mass each person has. A normal person BMR is the calculation of calories that each organ requires to function with, while you aren’t performing any activity. The increase in mass of muscles increases BMR. It decreases with growing age and muscle mass. Total daily energy expenditure, TDEE is the total number of calories body consumes, daily, to function. The TDEE varies numerous factors, such as age, gender, and activity level. Men tend to have higher TDEE compared to women due to more muscle mass. BMR calculator for men and women is used to calculate the basal metabolic rate.
How to use the BMR Calculator?
At first, you have to enter your gender whether you’re a male or a female. Then there is an option to write age, height, and weight. Then there are five levels of activity. You have to choose one from them. The five levels of activity in the basal metabolic rate calculator are: After you have filled the information, the calculator your BMR in calories per day and the calories you require per day.
Factors that affect your BMR
How BMR can help in weight loss?
Another alternate definition of the Basal metabolic rate makes the relation between energy and calories really visible. It states that the Basal metabolic rate is the number of calories, required by an individual to survive or by the organs to keep functioning even when the digestive system is inactive. This statement also throws light on the relation between weight loss and BMR.
Weight is lost when the total amount of calories consumed by a person are lesser than the ones that are burnt by the individual. BMR plays a very major role in weight loss which has been elaborated below.
1- Knowing the BMR – A starting point for weight loss
Basal metabolic rate and its knowledge are considered as a ‘’starting point’’ for the weight loss process.
The initial advice given by the experts to anyone who plans on losing weight is the calculation of the basal metabolic rate.
Weight is reduced and lost once a person’s total caloric intake becomes lesser than the calories that the individual is burning throughout the day. And therefore, after knowing the BMR, you are easily put into the state of knowing how to reduce the number of calories that you consume every day. And obviously, once you do it, weight loss will easily follow afterwards. Basically, it provides you with a rough idea of the number of calories you require each day to lose some weight keeping in view the number of calories your body is ‘’naturally’’ burning through the process of doing nothing but existing.
2- You burn your calories while staying at rest
Sari Greaves who is a well-known dietician describes the calories burnt at rest as ‘’Couch-potato calories’’. Which when thought of, is practically true as you are burning those calories, not because of exercising or engaging yourself in some activity, but only because your organs are performing their activities. And more interestingly, it makes up 60 percent of the calories that you have consumed per day. The left over 40% are lost through your activities.
3- An estimation of your total calorie intake if you aim at losing weight
Long ago, people did not have the concept of obesity and how it can impact a person’s health. Then came the duration, when people only lost weight for social acceptance. However, in this world where science has progressed at its best, people are now aware of how overweight/obesity can affect the quality of life. From certain kinds of cancers to different heart diseases, all are accompanied by obesity.
Therefore, the concern towards weight is increasing day by day. And if you are someone who is all about fitness, you already know how you can calculate your total calorie intake that you need to maintain to lose some pounds. This also makes the importance of BMR in the weight-world, crystal clear.
To ascertain the calories you have to keep up your present weight, multiply your BMR by an activity factor. For example, you work in an office where your job is to sit on the desk all day long, your activity factor will be around 1.2. If however, you exercise twice or thrice a week, your movement factor is 1.375. And if you increase your exercise level by instead of exercising for twice or thrice a week, you exercise 3 to 5 times per week, then your action factor increases to 1.55. In case you're associated with games and exercise six to seven days seven days, your action factor is 1.725. In case you're preparing for a long distance race or have a physically engaging activity, your action factor is 1.9.
To make it even more clear, let’s explain it with an example. Consider a male individual of 43, with a height of 5’9 and a weight of 88. His BMR will fall around 1863 (you will require a accurate BMR calculator to calculate the value. We have mentioned the one you can use at calculators.tech for ease) if he is lightly active. To know the total amount of calories he needs to lose weight, simply multiply the BMR with the activity factor. And you get the desired result.
4- BMR can be altered for weight loss
People have noticed and reported, that when they start with the weight loss, they lose weight real quick. After shedding some pounds in a short duration, the process slows down and so, they lose weight very slowly. This is simply because your Basal metabolic rate decreases as you lose weight, and this means that the total calories needed by a person per day also shows a decrease.
The reason why this happens may be partially due to a decrease in muscle mass. For this purpose, experts suggest going for exercises such as squats, strength training, push-ups and etc. to maintain the BMI to some extent. (Ask your gym instructor for further details) and to lose weight at the same rate.
