How many calories I have to eat to lose weight

The first question that arises when you want to lose weight is: how many calories do I have to eat to lose your computer? In fact, this calorie intake is directly responsible for its contribution to weight loss. In this article, find out how many calories you have to consume one day to lose weight.

How many calories I have to eat to lose weight? Calculate energy needs

To find out how many calories I need to eat to lose weight, you will have to estimate your energy needs. Good news, some scientific methods and calculations allow you to carefully estimate your daily energy requirement.

Basal metabolism

First of all, it is essential to calculate the basal metabolic rate. That is, the minimum quantity of energy necessary for the body at rest to guarantee vital functions: digestion, posture, organ functioning, body temperature maintenance, etc.

Here is the formula Harris and Benedict used to calculate the basal metabolic rate:

• For man = [13.7516 x Greutate (în kg)] + [500.33 x Înălțime (în m)] – (6,7550 x age) + 66,473
• For the woman: [9,5634 x Greutate (în kg)] + [184,96 x Înălțime (în m)] – (4,6756 x age) + 655,0955

For example, for a 35 -year -old woman who measures 1.60 me weighs 58 kg, we get a basal metabolism of:

554.6772 + 295.935 – 163.646 + 655.0955 = 1342

To meet her basic needs, this woman will therefore need 1342 kcal per day.

The level of physical activity – how many calories I have to eat to lose weight

To calculate how many calories I eat to lose weight or as per day is necessary for the body, we must also consider the level of physical activity. In fact, in addition to guaranteeing its vital needs, the body spends further calories related to daily activity. Therefore, the estimated basal metabolism above must be multiplied with a coefficient corresponding to the level of daily activity.

To give the example of the woman 35 -year. If his daily physical activity is moderate, his basal metabolism must be multiplied by 1.55 to obtain his daily calorie requirements, that is 2080 kcal.

Total energy requirement – How many calories I have to eat to lose weight

Due to previous calculations, we have obtained an estimate of the total energy requirement. In our example, it is 2080 kcal. In other words, consuming 2080 kcal a day, this woman does not increase weight and will not lose weight. Be careful, however, this calculation has some limitations. To know the needs in the most accurate way possible, it is advisable to consult a nutritional specialist. Only it will be able to adapt this calculation based on your organization and its specific needs.

So now I think it is clearer about the answer to the question of how many calories I need to lose weight.

Importance of the right number of calories per day to lose weight

When it comes to weight loss, it is balance. Calculating the right number of calories per day to lose weight is an essential step.

Here are the 3 possible situations:

• Energy intake is equal to the energy requirement: the weight remains stable
• Energy intake is lower than the energy requirement: there is weight loss
• Energy intake is greater than the energy requirement: there is a weight gain

To lose weight, we believe it is necessary to induce an energy deficit of 10-15% of the total energy requirement. In our example, it will be necessary to consume less than 1870 kcal per day for a significant weight loss.

Be careful, however, that the energy deficit is not too high with the risk of causing nutritional deficiencies and harmful adaptation mechanisms. In fact, under a number of calories, the body is protected from the saving of energy and the conservation of different ingested calories. As a result, weight loss becomes increasingly difficult and the inevitable yo-yo effect.
