Long ago during our primitive days as human beings, even before history was written, our needs have been gradually increasing over time. From simply addressing the goal of eating three times a day, building a house that can shield us from the harsh climate, and clothing ourselves to be comfortable of the dangers of the changing surroundings, by achieving these we have obtained and started a flourishing civilization that will mark men’s conquest in further discovering the locked chambers of a seemingly high pyramid – The Maslow’s Hierarchy of Needs.
Now, in the 21st Century, the Homo sapiens, have uncovered the summit and discovered the need for aesthetics. In the hierarchy, it is located at the top portion since it is achieved only by people who have earned considerable amount of fortune.
Everyone has set their eyes upon the perfection of their physique; the enhancement of their nose, lips, eyes, and even their bosoms and butts are no exception. But the main catalyst that sparked the beginning of the Aesthetics Era is the natural way of halting the gain of weight.
Gaining of weight is primarily caused by the excessive consumption of calories that have not been burned due to lack of physical activities. In short, body weight increases when energy input exceeds energy output.
Fortunately, our body automatically consumes energy because our cells need it in order to perform work. With this, we have a Basal Metabolism Rate, in which it is the average rate of calorie burning our body does. Though the BMR differs depending on the person’s body, temperature, and other necessary factors, it is readily computed by the formula:
Kilocalories per hour per square meter body surface x Surface area of your body in square meters.
To get the kilocalories per hour per square meter of body surface, refer to the table below:
Kilocalories per hour per square meter of your body in sq. m.
Age Male Female
10-12 51.5 50.0
12-14 50.5 46.5
14-16 46.0 43.0
16-18 41.0 38.0
18-20 41.0 38.0
20-30 39.5 37.0
30-40 39.5 36.5
40-50 38.5 36.0
50-60 37.5 35.0
60-70 36.5 34.0
Now, to acquire the surface area of your body in square meters, another formula should be followed:
Weight in kilograms raised to the power of 0.425 x Height in centimeters to the power of 0.725 x 7184 and divide your answer by 1000 squared
Now you have your BMR per hour, if you want to know your rate in a day, just multiply it by 24.
By knowing your BMR you have known your metabolism rate without doing exercise or any physical activities.
Assuming that you are a 15 year-old male, having a weight of 52 kilograms and a height of 176 centimeters, by using the formula you acknowledge the fact that your BMR is a little bit more than 1800 kilocalories per day.
Knowing just your BMR is not enough, because what if your BMR is at 1800 kilocalories per day but you consume 3000 Kilocalories? Wouldn’t you have an accumulated 8400 kilocalories for a week [(3000x7)-(1800x70)] and for your information, a kilogram of adipose tissue is synthesized for every 6,600 kilocalories. In short, with this rate, you will gain 1.27 kilograms for a week.
Basically, in order to reduce your weight, you should not eat excessively. Another thing, before and after you eat, you should drink ice-cold water in order for your stomach to metabolize more energy so that it could heat up and lose more energy. Another thing, shivering is also one way to increase metabolism rate.
At most, weight reduction is achieved through meticulously maintaining a balanced diet that doesn’t exceed your BMR unless if you workout, also joining physical activities is one way to help maintain a healthy weight.
Meticulous maintenance is always the key!
