calculate your BMR

Your daily energy requirement can be known by calculating your Basal Metabolic Rate, or your BMR. The number of calories represents how much your body consumes simply to keep resting while carrying out necessary processes such as breathing, regulating the body temperature, and circulating blood. For example, when you are on a diet, a BMR calculator will become one of the most useful tools that can readjust your energy intake to fit your needs. In this blog post, we guide you through the process of BMR calculation, plus the main distinction between BMR and TDEE, and how such figures impact your daily caloric intake.

What is BMR?

Basal Metabolic Rate is the amount of calories your body requires to maintain simple functions when at rest. Even if you are not moving out to do any kind of exercise, your body still requires its energy to accomplish vital operations like digestion, cell repair, and heart operation. You can use a BMR calculator to estimate the number of calories your body needs on an average basis.

How to Calculate BMR

There are some formulas to calculate BMR. One of the most popular is the Mifflin-St Jeor Equation, which considers your weight, height, age, and sex. Here it is:

Mifflin-St Jeor Equation:

  • For Males:

BMR = (10 x weight in kg) + (6.25 x height in cm) – (5 x age in years) + 5

  • For Females:

BMR = (10 x weight in kg) + (6.25 x height in cm) − (5 x age in years) − 161

To simplify this, you can use a basal metabolic rate calculator or an online BMR calculator. You need to just enter your information there and it will calculate all for you.

What is TDEE, and How Does It Relate to BMR?

While BMR is a reading of the calories your body burns at rest, TDEE (Total Daily Energy Expenditure) gives you a better reading of all of the calories that are needed. This takes into account everything you do, from exercise and walking to even fidgeting.

To determine TDEE, you multiply your BMR times an activity factor:

  • Sedentary: BMR × 1.2
  • Lightly active: BMR × 1.375
  • Moderately active: BMR × 1.55
  • Very active: BMR × 1.725
  • Super active: BMR × 1.9

With the use of a TDEE calculator, this work becomes easier. It takes your BMR and adds it to your activity level for the day and helps you to achieve a more accurate explanation of how much energy your body needs.

Why Use a BMR Calculator to Lose Weight?

Knowing how to calculate your BMR is useful if you’re targeting weight loss, as you can then set about making a calorie plan for yourself. To lose weight, you must have a calorie deficit-you need to consume fewer calories than your body burns.

For example:

  • Maintenance: If you consume at your TDEE level, you maintain your current weight.
  • Weight loss: if you can consume 10-20% fewer calories than your TDEE, then you begin to lose fat.
  • Gain weight: Taking in excess calories over your TDEE will help you in gaining muscle mass or weight gain.

By using a BMR calculator to lose weight, you will ensure that you are neither under nor over-eating and maintain the energy balance optimized.

Advantages of Knowing the Metabolic Rate

  1. Calculation Accuracy in Diet Planning: A metabolic rate calculator helps design diet aimed at desired goals-losing weight, maintaining weight, or gaining muscles.
  2. Better Energy Management: Knowledge of TDEE ensures that your body is well supplied with proper fuels, which eliminates cases of fatigue and energy crashes.
  3. For Long-term Health Management: Through the BMR, a regular follow-up and necessary adjustments can be made as changes in lifestyle are discussed.
