What Are Calories?
One of the questions people research the most on the Internet is “how many calories should I eat a day”. There are different categories and tables that serve as guidelines for different people, depending on age, sex, pregnancy, breastfeeding, the intensity of physical and mental activity, etc. At the same time, there are different criteria upon which you should determine your daily calorie intake.
In this article, we will answer some of the burning calorie intake issues, including “how many calories should I eat to lose weight”, “how many calories to lose a pound”, and determine the caloric values of certain foods.
First, let’s learn more about calories.
A calorie is a unit of energy. In the International System of units, Joule is used as the standard unit for energy, and calories are used as a measure of the energy in metabolism that is needed for the body to function, as well as for the energy stored in food.
Types of Calories
Scientifically, there are two types of calories:
- Low calorie or gram of calories (abbreviated “Cal”) – represents the amount of energy required to increase the temperature of one gram of water by one degree Celsius;
- High calorie, kilo-calorie – strong or nutritional calorie (abbr. “kcal”) – the amount of energy needed to increase the temperature of one kilogram of water by one degree Celsius.
Calories in Foods
When it comes to calories in food, one gram of calories is a very small amount to define the nutritional value of any food. Therefore, we use the term “kilo-calorie“.
In general, humans and animals need a certain minimum amount of energy per day in order to maintain the basic vital processes in the body and its functions, such as breathing, maintaining body temperature, organ functions, blood circulation, and others.
This minimum amount of energy is called basal metabolism or BMR (basal metabolic rate) and implies the energy needed when our body is at a state of rest. However, all our additional activities consume additional energy, so it is necessary to intake a larger amount of energy than the minimum, depending on our needs.
All the energy that our body needs is provided by food intake, and the number of calories in food shows how much potential energy food has.
On the nutritional labels of many products, you can notice several main parameters that always stand out, and these are proteins, fats, and carbohydrates. These three items are the main sources of energy. Other parameters such as water, fiber, indigestible substances, minerals, and vitamins do not participate in energy production.
A gram of carbohydrates has 4 calories, a gram of protein has 4 calories, and a gram of fat has 9 calories. Another source of energy that exists is alcohol which has 7 calories per gram.
Every food or dish has a certain combination. The combination consists of mainly these three first sources and gives a certain number of calories, or a certain amount of energy. Carbohydrates, proteins, and fats are needed by the body for maintaining its vital functions.
By burning calories through metabolism, enzymes convert carbohydrates into glucose and other sugars, fats into glycerol and fatty acids, and proteins into amino acids. Then, these molecules are further absorbed through the bloodstream for immediate energy, building material, or simple storage for later use.
How Many Calories Should I Eat A Day?
How many calories our body needs each day significantly depends on how physically active we are. In this section, you will find out how many calories you need to ingest per day depending on how much you move and exercise.
If you want to maintain a healthy weight and not gain weight, check what your ideal number is when it comes to calories, determined based on your physical activity:
- Very active: If a person exercises for an hour or more every day or does a very physically demanding job, the daily calorie intake for women should be 2000 to 2500 calories and for men 2500 to 3000 calories.
- Moderately active: People who exercise 30 to 60 minutes a day – women should ingest 1900 calories and men 2500.
- Low activity: People who take 5,000 to 8,000 steps a day will need to ingest 1,800 calories (women) and 2,200 calories (men).
- Sedentary lifestyle: For people who spend most of the day sitting and doing less than 5,000 steps a day, the number of calories consumed should not exceed 1600 for women and 1800 for men.
How Many Calories Should I Eat To Lose Weight?
Now, let’s come to the burning question: “how many calories should I eat to lose weight”. The principle of losing weight is simple – if you want to lose weight, you should eat fewer calories than the daily recommended number for your age and gender.
This is also related to your physical activity. You should eat 200 calories less than the required number for your specific lifestyle. For example, 1400-1500 if you lead a sedentary lifestyle, and 1600-1700 if you have low activity. You should take 1800 if you are a very active woman and 2300 if you are a very active man.

Make sure to do some sports on a daily basis or at least 2-3 times a week. In this way, you will establish a steady and healthy weight loss. Also, you will avoid sagging skin and weight loss-gain boomerang effect.
How To Determine The Number of Calories in Food?
Theoretically, there are several ways to determine the number of calories in a particular dish or food. Some of them are free enthalpy, measuring the amount of adenosine triphosphate formed during food metabolism, and measuring the heat generated by burning food in a bomb calorimeter.
Today, most of us use ready-made food calorie value tables. Those are made by nutritionists and scientists. You can use such a table from a trustworthy source in your daily caloric intake calculations.

An average man should consume up to 2800 kcal per day, and an average woman up to 2200 kcal. However, each person’s metabolism differs and the intake depends on many different parameters.
How many calories you need to intake every day depends on the age of the person, the gender, height, weight, activity, basal metabolism, the job he/she normally does, body composition, and, ultimately, genetics itself.
Additional factors that also affect the number of calories to be taken can be various diseases, pregnancy, hormonal disorders, and similar factors.
There are tools that make their calculations based on several data (height, age, sex, and current weight) to determine, roughly, how many calories are needed for proper basal metabolism (BMR calculator).
Then, based on the TDEE calculator, we calculate how many calories we consume during the day when our daily activities are taken into account.
Furthermore, based on these two data, we can know approximately how much energy our body needs and therefore how much food (calories) we need to ingest to maintain optimal body mass.
If we need about 2,000 kcal a day to maintain optimal body weight, then anything we ingest over 2,000 kcal will turn into adipose tissue and this causes weight gain. If we consume less than 2,000 kcal, there is a problem of lack of energy, which causes weight loss.
Finally, we can lose those extra calories through physical activity. In the following sections, we will deal with rates of burning calories through different types of activities.
Physical Activity And Burning Calories
We all know that all kinds of physical activities lead to burning calories. In the modern way of life, where most adults are in the house-car-elevator-office relationship, man has forgotten that he was created to move.
You can often hear people say they had gained weight since they bought their car. In that case, the decision to introduce physical activity to one’s daily routine will help lose weight.
Some activities are true champions in burning calories, while others are not so beneficial.
If you are wondering how many calories does walking burns, you can be happy, as it burns a significant number of calories if we take into account that walking is not a very demanding activity. Of course, burned calories depend on the mass of the walker and pace too.
How Many Calories Does Walking Burn?
Here is a promising statement: walking at a certain pace with a healthy diet can help you lose weight and get in shape in only 5 weeks.
First of all, let’s remember that any activity, even walking, requires mental preparation if you want to achieve the effect of losing weight. Walking for more than 20 minutes falls into the category of aerobic training, which certainly makes a person work on improving their health.
Maximum oxygen uptake increases, the load on the heart decreases, and stress certainly decrease too.
However, a person who approaches walking without preparation and does not use the proper technique that includes both arms and legs, will not be able to burn enough calories.
If you want to lose weight by walking, it is very important to do it at the right pace. The best thing is the fact that when you walk fast, the deep abdominal fat tissue begins to melt first.
Another good news is that fast walking puts less pressure on the ankles than running. This is because your foot always touches the ground when walking, while during running there are moments when the whole body is in the air and when you land on the ground, the body is exposed to the impact.
Tips for Burning More Calories Through Walking
Here are some tips that will help you lose more calories through walking. If you follow these tips, combined with a healthy diet, you can lose up to 5 pounds in 3 weeks, and you can walk anywhere and anytime.
For maximum fat loss, walk at a fast pace three times a week for 30 minutes. You can walk these 30 minutes at once or you can interrupt them with short breaks during which you will walk more slowly, take some water or stretch.
If you walk at a pace you usually use for shopping and walking in the streets, you can burn 238 calories in one hour. This walking intensity is usually marked as 4 on a scale of 10.
If you prefer fast walking, which implies walking at a speed of 5 or 6 on a scale of 10 or walking six kilometers per hour, you will burn 340 calories in an hour.
As you walk at this speed you can speak, but after every few sentences, you need to get some air. This marker can help you determine your pace.
Strong and fast walk – the speed is about 8 kilometers per hour, and you will burn about 564 calories per hour. Walking at this pace implies waving your arms for greater air deflection and walking at greater steps.
As a result, you should walk at a speed of 7 or 8 on a scale of 10. If you walk fast enough, you will hardly be able to speak, only three or four words in a row because you will have to concentrate on breathing.
Furthermore, you should pay attention to the movements of your body. During each step on the leg, you should actively contract the leg muscles. Also, you should feel that your abdominal wall is compressed.
You must catch the walking pace that will lead you to an anaerobic zone where you will feel unable to breathe enough air. This may initially happen after just a few minutes, but will gradually lengthen as the body adapts.
How Many Calories Are Burned in 10000 Steps?
We have already seen that walking burns so many calories. You should definitely walk every day for several kilometers or miles. To be specific, if you pass 6 km per hour, you can burn between 300 and 500 calories, depending on your weight.
Calorie calculation is a widespread, well-known, and popular method of calorie intake control. An average adult man needs 2800 kcal per day, while an adult woman who is not pregnant nor breastfeeding needs 2200 kcal per day. These are the values required for maintaining the current weight.
However, if you want to lose or gain weight, you will need to decrease, i.e., increase your calorie intake on daily basis. Moreover, your needs depend on your physical activity.
Related to this, burning calories with physical activity is the very best and natural way of keeping your weight on the desired level or losing weight. Walking is one of the best methods. Adjusting your pace and length of walking on a daily basis will increase your calorie-burning efficiency.
Finally, referring to a list of caloric values of different foods shows us that certain fruits and most vegetables are least-caloric foods. White meat, such as chicken is also low-calorie rated food. Most importantly, you must prepare your foods in a healthy way. This significantly affects the caloric value of foods.
