Calories are units of energy. It refers to the energy one gains from food and drinks and which they use up to perform various bodily functions. At present, most people are health conscious, and they keep track of their calorie intake. Food packages mention the calorific content of their products, and there are diets which focus on the low-calorie intake to reduce or gain weight. However, still there are hundreds of people asking How Many Calories Do I Burn a Day? To answer the same, we’ve created this guide for you.
Calories are essential for our body, and the key is to regulate how much to consume. Food high in energy, but low in nutritional value, contributes empty calories. Calorie requirement differs from person to person, depending on age, height, weight, gender and activity levels.
The uncontrolled consumption of fast food gains most calories. According to health experts, an average man needs 2,700 kcal per day. On the other hnd, it is 2,200 kcal per day for an average woman.
On our most quiet days, when we don’t do any physical work, our body is still burning calories while performing the essential life functions.
The number of calories burnt at rest is referred to as Basal Metabolic Rate or BMR. It is a measure of all the energy that our body expends to keep the organs running and functioning normally.
Our heart needs to pump blood to all corners of the body, our lungs need to breathe, and our brain needs to control all these functions and keep us alive. A considerable amount of energy is burnt as calories to perform each of these functions. Hence, the notion that one only expends calories during strenuous physical work is wrong.
How Many Calories Do I Burn a Day?
The answer to the question on how many calories does a person burn doing nothing depends on a lot of other factors.
It depends on the age, weight, height, gender. A male burns more calories than a woman in general. People with more weight expend calories while younger people lose more calories than older ones.
To find accurately, the number of calories, and you simply have to enter the data into the formula below or you can use our TDEE Calculator for the same.
• For Women: resting metabolic rate = 655 + (4.35 x weight in pounds) + (4.7 x height in inches) – (4.7 x age in years)
• For Men: resting metabolic rate = 66 + (6.23 x weight in pounds) + (12.7 x height in inches) – (6.8 x age in years)
Suppose the height and weight of a woman of 40 years age is 63.7 inch and 168.5 pounds respectively, then on putting in these values in the formula, then 1,499.365 is her resting metabolic rate.
In other words, for a 40 years old woman, they usually burn 1,500 calories doing nothing at home per day.
The values calculated are applicable to healthy people with a normal diet. They are not for people on a low calories diet for a long time. The BMR is reduced in such cases as a result of certain factors like reduced secretion of thyroid hormones. The metabolism also changes due to illness like fever, injuries, and other conditions.
Doing nothing doesn’t necessarily mean absolutely lying still and asleep. Although even at this rest position too, our body burns calories by the functioning of organs to keep us alive. However, more often, doing ‘nothing’ refers to the basic minimum work a person does during the day. This involves sitting, regular walking, reading, moving your hands for basic needs.
It, however, excludes any forms of exercise, fast movements or extensive physical activities.
Studies recommend that sedentary adult women between the ages of 36-50 should have a daily calorific intake of 1,800 calories. Also, to make up for all the calories that they burn doing nothing during the day.
An average, 30 years old man, of 5 feet, 10 inches tall, 150 lbs weight, and of a normal build, roughly burns 61 calories per hour. While sitting around and watching television, he burns 68 calories each hour, or 1,632 calories each day. Again, if the same man were to sit down and read, he would burn 88 calories per hour, which is nearly 2,112 calories in a day.
When your calorie intake is higher than its expenditure, you are most likely to gain weight. Since your body stores all the extra calories as fat in muscle tissues. Similarly, if your calorie intake is lower than your expenditure, you will lose weight.
Hence, your BMR is an indication of whether you need to increase or lower your calorie intake and accordingly, include or remove those items from your daily diet.
The next time you feel guilty about lying around the whole day, don’t stress out. Remember, being lazy and doing absolutely nothing while your friends are working out is also fun. Keep in mind that you are burning some calorie anyway! So, this was all about your question How Many Calories Do I Burn a Day.
