After reading the article, you will know what calorie calculators are and how to calculate your calorie intake by yourself per day or meal. You will also finally understand how different factors (age, size, activity) affect calorie intake. Your goal is already close!
Would you like to get rid of excess calories or gain weight? Would you want to know how many calories you need to consume per day? And how does it depend on age and activity? Let's find it out!

First of all, it all starts with calories!
Kilocalories are a unit of measure for the nutritional value of foods. This indicator shows the daily rate1 of energy consumed.
The calorie intake depends on the age, weight, and gender of the person, as well as the level of physical activity and diet. Any diet begins with determining the required number of calories.
For this reason, the calculation of the daily calorie intake is an important step from which to start your journey to the figure of your dreams. To lose weight, you need to spend more energy than you consume with food.
To develop a quality calorie intake, pay attention to your age and lifestyle2. They will determine how many calories you need per day. Later, you can adjust these numbers depending on your weight goal3.
With sedentary lifestyle:
19-30 years old - 2300-2500 kcal
31-50 years old - 2100-2300 kcal
50 years and older - less than 2000 kcal.
With a moderately active lifestyle, these figures are approximately equal to 2700, 2500 and 2300 kcal. For athletes and active people - 3000, 2900, and 2600 kcal.
With sedentary lifestyle:
19-25 years old - 1900-2100 kcal
26-50 years old - 1700-1900 kcal
over the age of 50 - 1500-1700 kcal.
For girls who lead a moderately active lifestyle and who have not yet turned 25, energy consumption is on average 2100-2300 kcal. At the age of 26 to 50 years - 2000-2100 kcal and over the age of 50 about 1700-1900 kcal. For active women and athletes, these figures are 2300-2500, 2100-2300, and 1900-2000 kcal.
The calorie calculator determines how many calories a person should consume per day based on their metabolic rate. Not all such calculators are equally good.
We offer you an option that you can use yourself. To calculate your daily calorie intake, you need to take a few steps. So, here is the calorie counting algorithm:
Each of us, depending on weight, activity, and age, requires a different amount of food. To find out the exact figure, you need to use the Harris-Benedict formula:
Women: BMR = 9.99 * weight (in kg) + 6.25 * height (in cm) - 4.92 * age (number of years) - 161
Men: BMR = 9.99 * weight (in kg) + 6.25 * height (in cm) - 4.92 * age (number of years) + 5
(where BMR is the basal metabolic rate).
Here you need to determine the coefficient of your physical activity:
1.2 - minimal activity (lack of physical activity, sedentary work, minimum movement)
1.375 - little activity (light exercise or walking, little daily activity during the day)
1.46 - average activity (training 4-5 times a week, good activity during the day)
1.55 - above average activity (intense training 5-6 times a week, good activity during the day)
1.64 - increased activity (daily training, high daily activity)
1.72 - high activity (daily ultra-intense training and high daily activity)
1.9 - very high activity (usually we are talking about athletes during the period of competitive activity)
So, multiplying the BMR figure by the physical activity coefficient, we got your calorie intake. Eating within the limits of this norm, you will neither lose weight nor gain weight. This is the so-called norm of calories for weight maintenance.
BMR * Activity Ratio = Calorie requirement for weight maintenance.
Considering that you need to create a calorie deficit for weight loss, the approximate calculation per meal to lose weight will be 200-400 kcal.
|1st snack||10-11 a.m.||300|
|2nd snack||16-17 a.m.||300|
If you set a goal to lose weight, you will have to reduce the daily intake by 20% - this is the most physiological approach. Then, with a physiological norm of 1800 kcal, you will need to eat only 1440 kcal per day to reduce weight.
Drastic dietary cuts of more than 20% pose health risks. But if you are obese and tend to overeat, your doctor may recommend a 40% reduction in your diet. However, cut it not from the physiological norm, but from the number of calories that you are used to eating every day.
A 1500 calorie diet is a bland diet. A simple diet for a given number of calories allows you to painlessly remove extra pounds5. A person will not have to starve, but there will not be an overabundance either.
For muscle growth, you need to get 10-15% more calories6 than with your standard diet. Men are recommended to focus on + 200-300 kcal, and women - on + 150-250 kcal per day.
It’s better to keep track of how many calories you need to eat in order to lose weight, and not to rush anywhere. Use calorie calculators and follow the rules of a balanced diet.
Healthy nutrition experts advise against trying to lose weight drastically by extreme cutting calories. Natural weight changes should be about 2-4 pounds (1-1.5 kg) per week. This is the most comfortable rate of weight loss to slim down effectively!
