Body Mass Index (BMI) Calculator Tool

Basal Metabolic Rate Calculator

• Gender:
  • Male
  • Female
• Age:
• Height: (in centimeters)
• Weight: (in kilograms)
• Activity level:
  • Sedentary
  • Lightly active
  • Moderately active
  • Very active

To use the calculator, simply enter your gender, age, height, weight, and activity level. The calculator will then calculate your basal metabolic rate (BMR). Your BMR is the number of calories your body burns at rest. It is the amount of energy your body needs to function at its most basic level.

Your BMR can be used to estimate your total daily calorie needs. To calculate your total daily calorie needs, you need to multiply your BMR by your activity level. For example, if you are a sedentary male who is 25 years old, 175 centimeters tall, and weighs 75 kilograms, your BMR is 1,800 calories per day. If you are lightly active, your total daily calorie needs are 2,340 calories per day. If you are moderately active, your total daily calorie needs are 2,880 calories per day. And if you are very active, your total daily calorie needs are 3,420 calories per day.

Your BMR can also be used to track your weight loss or weight gain progress. If you are trying to lose weight, you need to create a calorie deficit. This means that you need to eat fewer calories than your body burns each day. You can create a calorie deficit by eating less food, exercising more, or both.

If you are trying to gain weight, you need to create a calorie surplus. This means that you need to eat more calories than your body burns each day. You can create a calorie surplus by eating more food, exercising less, or both.

It is important to note that BMR calculators are just estimates. Your actual BMR may be higher or lower than the calculated value. If you are trying to lose weight or gain weight, it is important to track your calorie intake and expenditure over time to make sure that you are on track.

Basal metabolic rate (BMR) is the number of calories your body burns at rest. It is the amount of energy your body needs to function at its most basic level. This includes activities like breathing, circulating blood, and keeping your organs functioning.

Your BMR is affected by a number of factors, including your age, sex, height, weight, and body composition. As you get older, your BMR naturally decreases. Men also have higher BMRs than women, on average. And people with more muscle mass have higher BMRs than people with less muscle mass.

There are a number of ways to measure BMR, but the most common method is to use a metabolic cart. A metabolic cart is a device that measures the amount of oxygen you consume and the amount of carbon dioxide you exhale. This information is used to calculate your BMR.

You can also estimate your BMR using a BMR calculator. BMR calculators are available online and in many health and fitness magazines. However, it is important to note that BMR calculators are just estimates. Your actual BMR may be higher or lower than the calculated value.

If you are trying to lose weight or gain weight, it is important to know your BMR. This will help you to create a calorie deficit or surplus, as needed. You can use a BMR calculator to get an estimate of your BMR, but it is important to track your calorie intake and expenditure over time to make sure that you are on track.

Here are some additional things to know about BMR:

• BMR is not the same as total daily calorie needs. Your total daily calorie needs will also include calories burned through physical activity and the thermic effect of food (TEF).
• BMR can fluctuate throughout the day, depending on your activity level, food intake, and temperature.
• BMR can also be affected by certain medications and medical conditions.

The following are the factors that can affect your BMR:

• Age: Your BMR naturally decreases as you get older. This is because your body composition changes as you age. You lose muscle mass and gain fat mass, both of which can lower your BMR.
• Sex: Men typically have higher BMRs than women. This is because men have more muscle mass than women.
• Height: Your BMR increases with your height. This is because taller people have more cells and tissues, which require more energy to maintain.
• Weight: Your BMR increases with your weight. This is because more weight means more cells and tissues, which require more energy to maintain. However, it is important to note that muscle mass is more metabolically active than fat mass. So, if you gain weight in muscle, your BMR will increase more than if you gain weight in fat.
• Body composition: Your BMR is higher if you have a higher percentage of muscle mass and a lower percentage of body fat. This is because muscle tissue is more metabolically active than fat tissue.
• Activity level: Your BMR increases with your activity level. This is because your body needs more energy to perform physical activity.
• Environment: Your BMR can be affected by the environment you are in. For example, your BMR will be higher if you are in a cold environment than if you are in a warm environment. This is because your body needs to burn more calories to keep warm.
• Hormones: Your BMR can be affected by certain hormones, such as thyroid hormone. Thyroid hormone helps to regulate your metabolism, and low levels of thyroid hormone can lead to a lower BMR.
• Medications: Some medications can affect your BMR. For example, beta-blockers, which are used to treat high blood pressure, can lower your BMR.
• Medical conditions: Some medical conditions can affect your BMR. For example, hyperthyroidism, which is an overactive thyroid, can lead to a higher BMR.

If you are concerned about your BMR, you should talk to your doctor.
