# How to Know How Much Calories You Need?

Calories are the units of energy we get from food. They are essential to maintaining our body’s normal functions, such as breathing, pumping blood, and building muscle. Knowing how many calories you need each day can help you maintain a healthy weight and prevent chronic diseases like obesity and type 2 diabetes.

There are several ways to determine your daily calorie needs. The most accurate method is to use a professional nutritionist or dietitian who can calculate your personal needs based on your height, weight, age, activity level, and health history. However, there are also online calorie calculators that can give you a rough estimate.

## The following are the steps to determine your daily calorie needs:

Calculate your Basal Metabolic Rate (BMR) BMR is the amount of energy your body needs to function while at rest. It accounts for about 60 to 75 percent of the calories you burn each day. You can calculate your BMR using the following formula:

For women: BMR = 655 + (9.6 x weight in kg) + (1.8 x height in cm) – (4.7 x age in years)

For men: BMR = 66 + (13.7 x weight in kg) + (5 x height in cm) – (6.8 x age in years)

Determine your activity level Your activity level influences the number of calories you need. You can use the following activity level categories to determine the number of calories you need:

Sedentary (little or no exercise) = BMR x 1.2

Lightly active (light exercise or sports 1-3 days a week) = BMR x 1.375

Moderately active (moderate exercise or sports 3-5 days a week) = BMR x 1.55

Very active (hard exercise or sports 6-7 days a week) = BMR x 1.725

Extremely active (very hard exercise or sports, physical job, or training twice a day) = BMR x 1.9

Calculate your daily calorie needs Finally, you can calculate your daily calorie needs by multiplying your BMR by the appropriate activity level factor. This will give you an estimate of the number of calories you need to maintain your weight.

Adjust for weight loss or gain If you want to lose weight, you need to consume fewer calories than your body burns. A safe rate of weight loss is 1 to 2 pounds per week, which means reducing your daily calorie intake by 500 to 1000 calories. On the other hand, if you want to gain weight, you need to consume more calories than your body burns. A safe rate of weight gain is 1 to 2 pounds per week, which means increasing your daily calorie intake by 500 to 1000 calories.

In conclusion, knowing your daily calorie needs is essential for maintaining a healthy weight and preventing chronic diseases. There are several methods to determine your calorie needs, including online calorie calculators and professional nutritionist assessments. Remember to adjust your calorie intake for weight loss or gain and always consult with a healthcare professional before making any significant changes to your diet.
