Hello friends, it is a well known fact of life every things needs energy to move or grow. You can’t move any object by adding force or giving energy. Plant growth news energy they take energy from the soil in the form of nutrients. Nitrogen, phosphorus and potassium is the primary nutrients which provides energy. Same every automobile moves by consuming fuel. The fuel may be varied from hydrocarbons, to solar and electrical. Even machine run on either electricity, battery, steam and solar. Same is the case with man. Man need energy not only for growth and movement but also for the proper functioning of body parts like liver, brain, eyes, kidneys etc. Remember human organs need energy to survive.
Scientist and Engineer called this requirement of energy which keep your body function properly is called Basal Metabolic rate. It depends upon many things like you height and body weight and your age. As texture of man and female body is different so Basal Metabolic Rate is different for men and women. If you interested to know the BMR of you all you need to add value in below mentioned calculation.
BMR for Men = 66.47 + (13.75 * weight [kg]) + (5.003 * size [cm]) − (6.755 * age [years])
BMR for Women = 655.1 + (9.563 * weight [kg]) + (1.85 * size [cm]) − (4.676 * age [years])
Remember the value achieved by BMR is only to keep your body functioning properly when at rest. It doesn’t account any motion, movement and your life style work. The more you move the more energy you required. Your BMR is the basic number. You have to take extra energy to overcome your exercise. Moderate exercise give increase your BMR up to 1.5 times. Little or no exercise increase the value by multiple of 1.2 times. You can almost double your intake if you do high intensity exercise. But it is wise to diet balance food.
Now let's come to the point what is the source of energy for men. Men consume energy in the form of calories. Water has zero calorie but every food has calories. Human diet included following items.
- Carbohydrates
- Proteins
- Fats.
Each gram of carbohydrates give you four calories. While each gram of proteins carry 4 calories. Each gram of fats contains 9 calories which is 2.25 more than calories. This doesn’t mean that fat is not good for health. Fat is important for our body just like carbohydrates and proteins. It is important to eat the food in such away we don’t over eat or we don’t take extra calories. Things becomes out of control if you take extra calories. Let’s suppose your body needs 2,000 calories/day and consume 2,500 calories/day. With this pace at the end of week you will eat 3500 more calories which is equal to one pound. This means eating 500 calories/day will rise your weight one pound / week. This is enough to increase your weight 52 pounds in year. Great number. So remember these number If you gain one pound you have to take 3,500 more calories or if you want to gain 1 Kg you have to take 7,700 more calories. On the other hand if you want to loose one pound weight either you need to burn 3,500 more calories you intake or you consume 3,500 calories your body required. There are many other factors involved which I want to discuss in other post. Hopefully you will like my today’s post. I would love to read your comments your suggestion in comment section. Wish you a wonderful and blessed life ahead. Have a nice time! Stay home and save yourself from covid-19 pandemics. Have a nice time
