What is the difference between calories and kilocalories

Calorie counting is not as simple as it might seem, but it is important for everyone to know the basics.

Petr Yastrebov


Question answer


weight loss

We've collected the most common calorie-counting questions and tried to answer them as simply as possible.

What is a calorie?

A calorie is a unit of energy. One calorie is the amount of heat required to raise the temperature of 1 gram of water by 1 degree Celsius. Today, the concept of "calorie" is very widely used to assess the energy value - caloric content - of food. The calorie content of a product is the amount of energy that our body receives when digesting food.

Calories are usually measured in kilocalories: 1 kilocalorie (kcal) equals 1000 calories (cal). But there is one nuance that can sometimes be confusing: in oral speech, nutritionists, athletes and just healthy lifestyle activists often use the word "calories" instead of "kilocalories". Why? Yes, it's just easier to say. So don't be surprised if you hear "I had 500 calories for breakfast!" - be sure that your interlocutor ate as many as 500 kilocalories!

Why does our body need calories?

The calories in the foods we eat provide energy to keep our bodies functioning. This means that we need to consume a certain number of calories in order to sustain life. If a person receives too little energy from food for a long time, he risks dying from starvation (unless he has reserves in the form of subcutaneous fat). But if we consume too many calories, then we can gain weight because excess energy is stored as fat under the skin.

What determines the calorie content of food?

The calorie content of a product is determined by the amount of macronutrients it contains: proteins, fats and carbohydrates. Each of them has its own energy value:

  • 1 gram of protein contains 4 kcal
  • 1 gram of carbohydrates - 4 kcal
  • 1 gram of fat - 9 kcal

Some other nutrients (alcohol, sugar alcohols, fiber), but their role is much less. Unless we are talking about alcoholic beverages).

Is it possible to evaluate a product only by its calorie content?

The usefulness and value of food is not determined by the number of calories alone. For example, a beef steak (which contains protein, vitamins, and minerals) may provide more benefits to your body than a brownie of the same calorie content. That is, foods that have the same number of calories may differ in nutrient content. Foods that contain very few beneficial nutrients are sometimes referred to as "empty calories."

How does the calorie content of food affect body weight?

Our body weight primarily depends on our energy balance. When we get exactly as much energy from food as we spend on our entire life activity, body weight remains unchanged. When we get less than we spend, we lose weight. When we get more, on the contrary, we gain weight. The key to successful weight control lies in the ability to manipulate your energy balance.

How do I know how many calories I need?

There are many formulas available to help you estimate your approximate caloric needs. But it is important to understand that no matter which calculation method you choose, you will not be able to immediately find out your actual maintenance calorie level (when you are not losing weight and not gaining). Your energy costs and energy consumption are influenced by many factors that no formula or calculator can take into account. Therefore, we recommend taking the calculated value as a basis, and then, starting from it, empirically look for your actual calorie content.

8 facts about calories that everyone should know

June 21, 2017 Food

What are calories, why do we need them and how much is needed - answers to questions that concern everyone



1. A calorie is a unit of energy from food

Technically, one calorie is the amount of energy needed to heat one gram of water by 1 ºC. In one kilocalorie (kcal) - 1,000 calories, and in this case we are not talking about a gram, but about a kilogram.

What does the food have to do with it? Proteins, fats and carbohydrates, of which it is composed, contain energy. This energy is measured in calories.

2. Calories allow us to survive, create new tissues and provide energy for movement

Every time you eat, your body uses the incoming energy for a variety of purposes. It is primarily used to support vital functions such as regulating breathing and pumping blood.

The required minimum energy for survival is called the basal metabolic rate. Its value for adult women with normal weight is about 1330 kcal, for adult men with normal weight - about 1680 kcal Human energy requirements.

The remaining calories and nutrients are used to build and repair tissues. That is why a high-calorie diet is prescribed for burns. Building muscle mass also requires energy: new tissue cannot build itself.

Any additional calories expended during physical activity. And any movement counts. But if you don't burn off the rest, it will be stored as fat.

We tend to think of fat as the enemy, when in reality it is our strategic energy reserve in case of an emergency. True, its excess harms the body, increasing the risk of developing diabetes and other diseases.

Finally, there is also digestion: 10-15% of incoming calories are spent on this process.

3. Your body may need more than 2,000 calories per day

Two thousand kilocalories is an average. Individual energy requirements depend on age, gender, weight, activity level and goal: lose weight, get better, stay in shape. Use this calculator to find out your rate.

4. Quantity and quality of calories are equally important

You can also lose weight on sweets, if there are not enough of them, as one American professor did Twinkie diet helps nutrition professor lose 27 pounds. But the number of calories is only one side of the coin. The nutrients in food also matter.

Let's say you decide to have a snack. Fat-free biscuits with only 100 calories are not the best choice because they are low in nutrients and high in sugar. Peanut butter with 190 kcal will bring more benefits: it has less sugar, more protein and vitamins.

5. There are no negative calorie foods

It is believed that some fruits and vegetables are so low in calories that they require more energy to digest than they can provide. Lie. As already mentioned, the body spends 10-15% of incoming calories on food processing. So everyone else, albeit in a negligibly small amount, stays with you.

6. Calories from carbohydrates are not a universal evil

Some diets are based on limited consumption of carbohydrates. But the weight gain is not because of them, but because of the excess calories. So extra pounds can be gained on the chicken breast, if you absorb it without measure.

In general, carbohydrates and carbohydrates are different. Harmful ones like candy and soda are devoid of nutrients. Healthy foods such as whole grains and fruits, on the other hand, are rich in nutrients and fiber.

7. The 3,500 kcal rule is wrong

There is a common saying in dietetics that 3,500 kcal equals 0.5 kg (that is, if you consume 500 kcal less during the week, you will lose half a kilo). Such figures first appeared in 1958, but are now obsolete Farewell to the 3,500-Calorie Rule.

The bottom line is that weight loss is individual and depends on metabolism and other factors.
