Use this calorie calculator to determine BMI, BMR, daily calorie, and macros needs based on your height, weight, age, gander, and activity level.
In addition to determining the calories you need to maintain weight, use this as a calorie burner calculator and find out how many calories you need to burn to lose pounds. Then use the nutritional needs calculator and figure out how to break down those calories into carbs, protein, and fat.
Mifflin – St. Jeor and Harris-Benedict calculator (or equation) calculates your BMR (Basal Metabolic Rate), and its results are based on an estimated average. Basal metabolic rate is the amount of energy expended per day at rest (how many calories you would burn at bed rest).
Use a calorie calculator to estimate how many daily calories your body needs to maintain your current weight. These calculations are based on Mifflin St. Jeor and Harris-Benedict Calorie Calculator Solutions.
Mifflin – St. Jeor Equation for Calorie Calculator
To estimate BMR and daily calorie burn or total daily energy expenditure, use this basic Mifflin – St. Jeor calculator (or equation)1 :
| MEN | WOMEN | |
|---|---|---|
| BMR | (10 x weight) + (6.25 x height) – (5 x age) + 5 | (10 x weight) + (6.25 x height) – (5 x age) – 161 |
Harris-Benedict Equation for Calorie Calculator
| MEN | WOMEN | |
|---|---|---|
| BMR | 66.5 + (13.75 x weight) + (5.003 x height) – (6.75 x age) | 655.1 + (9.563 x weight) + (1.85 x height) – (4.676 x age) |
- For sedentary active = Doing little or no exercise in a day, spend most of the day sitting, with little or no exercise
- For light active = Exercise 1-3 times/week
- For moderate active = Exercise 4-5 times/week
- For active = Daily exercise or intense exercise 3-4 times/week
- For very active = Intense/hard exercise/sports 6-7 days a week
- For extra active = Very intense/hard exercise/sports and physical job or 2x training
What is a normal or good BMR?
Generally, a normal or good BMR is considered to be around 2000 kcal/day in healthy individuals regardless of gender.
Which BMR Is good, high BMR or low BMR?
BMR is a measure of how much energy the body is consuming. A higher BMR indicates that the body is consuming more calories. Whereas low use of energy or calories is represented by low BMR.
Therefore, it is good to have a high BMR, indicating that more calories are being consumed and that the body stores less energy as fat.
What are the methods of calculation of BMR?
The BMR can be identified either by the simplest process of performing an overnight laboratory test, performing a manual calculation using BMR equations, or using an online tool.
How to increase the BMR?
The body’s basal metabolic rate can be increased by either increasing the lean muscle mass, level of daily physical activity from their current.
Why do men have higher BMR than women?
The BMR of men is generally found to be higher than that of women. For example, when the BMR of a man of the same age and that of another woman is compared, weight and height are compared. It will turn out that the BMR of the male will be higher than that of the female concerned.
This is due to the fact that men tend to have more muscle mass than fat mass than women. In addition, men’s higher physical activity levels also contribute to increased BMR than women.
Is metabolic age calculated using BMR?
The metabolic age of a person is calculated by taking into account the BMR (Basal Metabolic Rate) values. Or in simple words, we can say that metabolic age is the number of calories that the body burns at rest, compared only to the average BMR of people of chronological age.
What affects BMR?
Various factors contribute to affect the body’s BMR values, some of which are notable:
- Gender
- Weight
- Height
- Age
- Ethnicity
- Weight history
- Body composition
- Genetics/heredity factor
- Motherhood
- Hormones
- Diet
- Fat content
- Internal/external temperature
What activities are involved in BMR?
BMR is considered to be the minimum amount of energy that is required to continue life processes that occur at their own pace. For example, any type of internal activity that your body is doing without requiring you to move can include the following:
- Breathing
- Cellular respiration
- Digestion
- Brain activity
- Heart pumping
- Blood circulation
- Biochemical reactions
- Maintaining internal temperature
