BMR FAQs

Here are some frequently asked questions about basal metabolic rate calculator:

Q1: What is Basal Metabolic Rate (BMR)?

Basal Metabolic Rate (BMR) is the number of calories your body needs to stay alive while you’re resting. It’s like the energy your body uses just to keep your heart beating and lungs breathing.

Q2: What is the formula for Calculating BMR?

To calculate your Basal Metabolic Rate (BMR), you can use following formula:

  • For Men:

    • BMR = (88.4 + 13.4 × weight in kg) + (4.8 × height in cm) − (5.68 × age)

  • For Women:

    • BMR = (447.6 + 9.25 × weight in kg) + (3.10 × height in cm) − (4.33 × age)

Q3: How can I increase my BMR?

Increasing your Basal Metabolic Rate (BMR) can help you burn more calories at rest. Here are some strategies to help boost it:

Build Muscle:Strength training increases muscle mass, which in turn raises your BMR since muscle burns more calories than fat.
Stay Hydrated:Drinking enough water is crucial for your metabolism. Cold water can also give your metabolism a slight boost.
Get Enough Sleep:Poor sleep can negatively affect your metabolism. Aim for 7-9 hours of quality sleep per night.

Q4: What is the major determinant of BMR?

The main factor that affects your Basal Metabolic Rate (BMR) is lean body mass. This includes muscles, organs, bones, and other non-fat parts of your body. The more lean body mass you have, the higher your BMR will be. This is because these parts need more energy to stay active, even when you are resting.

Q5: How does the BMR calculator work?

A BMR calculator tells you how many calories you need to stay alive while resting. It checks the energy used for breathing, blood flow, making cells, and processing food. This helps you know your basic energy needs and manage your diet and weight.

Q6: Why is BMR important?

Basal Metabolic Rate (BMR) is the number of calories your body needs to perform basic functions while at rest. It makes up about 60-70% of the calories you burn daily. Knowing your BMR can help you manage your weight by guiding how many calories you should eat each day.

Q7: How to calculate your ideal Basal Metabolic Rate?
Age Male (calories per hour) Female (calories per hour)
20–29 39.5 37.0
30–39 39.5 36.5
40–49 38.5 36.5
50–59 37.5 35.0
Q8: How does weight affect BMR?

Weight affects BMR (Basal Metabolic Rate) in the following ways:

  • Higher weight means a higher BMR because more body mass needs more energy.
  • More muscle increases BMR since muscle burns more calories than fat.
  • Losing weight can lower BMR as the body uses less energy.

Q9: How is basal metabolic rate measured?

BMR (Basal Metabolic Rate) can be measured in the following ways:

  • Lab Testing: The best way to measure BMR is in a lab with a device that checks your breath to see how many calories you burn.
  • Gas Analysis:You can also measure BMR by seeing how much oxygen you use and how much carbon dioxide you make while resting.

Q10: What is the difference between BMR and TDEE?

BMR and TDEE:
Your BMR is the number of calories your body needs to survive. When you add the calories you burn through daily activity and exercise, you get your TDEE. You use TDEE calculator to figure out how many calories and nutrients you need to reach your goals.
