Calories are the energy we need to carry out our daily activities. They come from the food we consume and are essential for our body to function properly.

However, the amount of calories we need varies according to different factors such as age, height, weight, and activity level. In this article, we will be analyzing tables that provide information about the calories required by age groups.

Calories and Age

As we age, our body’s metabolism slows down and we require fewer calories. Children and adolescents, on the other hand, need more calories as they are growing and developing.

The following tables provide information on the estimated daily calories required by different age groups. Please note that these are general estimates and may not apply to everyone.

Infants and Children

During the first year of life, a baby’s calorie intake is mostly from breastmilk or formula. As they grow, they start to eat solid foods as well. The table below shows the estimated daily calories required for infants and children up to the age of 12:.

Age	Gender	Estimated Calories
0-5 months	Both	Approx. 500-600 calories
6-12 months	Both	Approx. 700-900 calories
1-3 years	Both	Approx. 1,000-1,400 calories
4-8 years	Both	Approx. 1,200-1,800 calories
9-13 years	Male	Approx. 1,800-2,600 calories
9-13 years	Female	Approx. 1,600-2,200 calories

Teens and Adults

Once we reach adolescence, our calorie needs increase due to growth spurts and increased physical activity. As we transition into adulthood, our calorie needs begin to level off and eventually start to decrease.

The following table shows the estimated daily calories required for teens and adults:.

Age	Gender	Estimated Calories
14-18 years	Male	Approx. 2,000-3,200 calories
14-18 years	Female	Approx. 1,800-2,400 calories
19-30 years	Male	Approx. 2,400-3,000 calories
19-30 years	Female	Approx. 1,800-2,400 calories
31-50 years	Male	Approx. 2,200-3,000 calories
31-50 years	Female	Approx. 1,800-2,200 calories
51+ years	Male	Approx. 2,000-2,800 calories
51+ years	Female	Approx. 1,600-2,200 calories

Factors Affecting Calorie Requirements

As mentioned earlier, there are several factors that can affect the number of calories a person requires. Some of these factors are:.

Weight and height
Physical activity level
Body composition (muscle mass vs. fat mass)
Gender
Age
Genetics

It is important to note that the tables we have analyzed provide only estimates of calorie requirements. For accurate information, it is recommended to consult a registered dietitian or nutritionist.

The Bottom Line

Knowing the number of calories required by different age groups is important for maintaining a healthy diet and lifestyle. However, it is important to remember that these are only estimates and individual requirements may vary.

By taking into account factors such as physical activity level, body composition, and genetics, a registered dietitian or nutritionist can provide personalized information on calorie requirements. Remember that a balanced diet and regular exercise are the key to maintaining a healthy weight and overall health.
