The number of calories a person should consume daily depends on several factors, such as age, sex, and weight . Taking these factors into account, calorie intake will vary from person to person.
In the following article we will give you a series of guidelines that will allow you to know for sure how many calories you should consume throughout the day.
Factors that will influence daily calorie intake
There are a number of factors that will directly influence the number of calories a person needs per day:
Age
Basal metabolism, or the amount of energy the body needs at rest to function optimally, varies with age. Children and adolescents require more calories than adults because they are still growing. As we age, metabolism tends to slow down, and with it, calorie needs.
Sex
Men typically have more muscle mass than women, which means they burn more calories at rest. Therefore, men generally require a higher daily calorie intake than women.
Weight and height
Weight and height directly affect the amount of energy a person needs daily. Taller people with greater body mass require more calories to maintain their vital functions.
Physical exercise level
The level of physical activity is one of the most important factors in determining calorie intake. People who exercise regularly will need more calories than those who lead a sedentary lifestyle. Physical activity increases energy expenditure and, consequently, calorie requirements.
Health goals
Health goals, such as weight loss, weight maintenance, or weight gain, will influence your daily calorie intake. If you want to lose weight, you need to create a calorie deficit by consuming fewer calories than you burn. If you want to gain weight, you will need a calorie surplus.
Calorie intake per day according to age
- Children from 2 to 8 years old will need to eat 1000 to 2000 calories daily.
- Girls from 9 to 18 years of age need to eat 1400 to 2400 calories daily.
- Children from 9 to 18 years of age need to eat 1600 to 3000 calories a day.
- Adult women from 19 to 50 years of age will need 1800 to 2400 calories a day.
- Adult men ages 19 to 50 need 2200 to 3000 calories daily.
- Adults over 50 years of age need 1600 to 2000 calories a day in the case of women and 2000 to 2800 calories a day in the case of men.
It's important to note that these recommendations should be tailored to the individual's needs. For example, someone with diabetes will require adjustments to their calorie intake. Similarly, pregnant women will need to increase their calorie intake.
Ultimately, determining the right number of calories to consume daily depends on several factors, such as age and sex. For most people, maintaining a healthy lifestyle, including a good diet and exercise, is the best way to ensure they are consuming the right number of calories for their individual needs.
