Calculating your calorie needs based on age is an important factor in maintaining a healthy lifestyle. As we age, our body’s metabolism slows down, and our calorie requirements change.
Knowing your calorie needs based on age can help you to achieve your fitness goals, whether you want to lose weight, maintain weight, or gain muscle mass.
Factors that Affect Calorie Needs
Before calculating your calorie needs based on age, it is important to understand the factors that affect your daily calorie requirements. These factors include:.
- Age
- Gender
- Height
- Weight
- Activity level
The Harris-Benedict Equation
The Harris-Benedict equation is a formula used to calculate a person’s basal metabolic rate (BMR), which is the amount of energy needed to maintain basic bodily functions when at rest.
From the BMR value, we can calculate daily calorie needs based on age and activity level.
The Harris-Benedict equation is as follows:.

How many calories do you need based on your age?
BMR for males = 88.362 + (13.397 x weight in kg) + (4.799 x height in cm) – (5.677 x age in years).
BMR for females = 447.593 + (9.247 x weight in kg) + (3.098 x height in cm) – (4.330 x age in years).
Calculating Daily Calorie Needs Based on Age
Once you have calculated your BMR using the Harris-Benedict equation, you can then calculate your daily calorie needs based on age and activity level. The following table will help you to calculate your daily calorie needs based on age:.

|---|---|---|---|---|
| 18-24 | 2400-2600 | 2600-2800 | 2800-3000 | 3000-3200 |
