People have different daily calorie needs, and this can be affected by their activity levels. A very active person’s daily calorie needs would be different from someone who is moderately active or completely sedentary. Daily calorie intake can also be different for people who want to lose weight or build muscle. If you’re on a weight loss journey, your calorie intake would be lower than someone who is trying to gain weight or build muscle.
This article will help you know how to calculate your daily calorie needs based on how active you are so you can maintain a healthy bodyweight.

BMR
To calculate the amount of calories you need every day, you need to know your BMR, which stands for Basal Metabolic Rate. BMR is the amount of calories your body burns when you’re resting, or just lying in bed doing nothing. Think of it as the energy you need to keep you alive. You can calculate your BMR using the Mifflin-St Jeor Equation, or an online BMR calculator, which gives you a good place to start for understanding your daily calorie needs.
How to Calculate Your Daily Calorie Needs Based on Your Activity Levels
Now that you know your BMR, the next step is to calculate your TDEE, which is your total daily energy expenditure. Your BMR multiplied by your activity Levels will give you your TDEE. Your activity levels have a huge impact on your daily calorie needs. They can be measured into several groups, and this is based on the amount of physical activity done daily.
1 . Sedentary: If you’re sedentary, this means you do little exercise, or don’t exercise at all, and you sit most of the day. It could be due to your type of job or other reasons. So if you’re in this category, you’ll multiply your (BMR x 1.2)
2 . Lightly active: You’re not sedentary, and you do light workouts or sports, 1 to 3 days a week. It’ll be (BMR x 1.375)
3 . Moderately active: You do moderate exercises or sports 3 to 5 days a week. For example, a moderately active person swims, cycles, or dances. And the calculation is (BMR x 1.55)
4 . Very active: You do hard exercises 6 to 7 days a week. Calculation will be (BMR x 1.725).
5 . Super active: You’re up and doing, no doubt. You do very hard exercises or sports, plus you have a physically demanding job. The calculation is (BMR x 1.9.
Say, your BMR is 1500, and you exercise 3 to 5 days a week, which is moderately active, this means you burn 2325 calories per day. So, if you want to lose weight, you’d eat 500 calories less than your TDEE. And if you want to gain weight, you’d need to eat 300 to 500 calories more than your TDEE. Bear in mind that TDEE is just another way of saying how many calories you burn a day. So, less than TDEE for weight loss is simply eating less and burning fewer calories per day, and weight gain is eating more calories than you burn per day. And if you simply don’t want to gain weight or lose weight, but want to maintain your weight. Just eat your exact TDEE.
