BMR Calculator For Diabetics

Use this BMR Calculator to find out your basal metabolic resting rate. This calculator will tell you how many calories that you would need to consume to maintain your body weight.

Click on the image below to download the zipped excel spreadsheet or click here.  

You can use the excel spreadsheet above in metric or US measurements.

First enter are your information where the font are in red i.e: weight, height and age also you will enter you activity level (refer to the legend in green) and your body fat (to find out your body fat check it online here).

Once you have enter all the data the amount of calories that you should be consume per day will be displayed.

To determine how much calories you need per day is the starting point to lose weight, burn fat and control your blood sugar, to understand check out Basal Metabolic Rate.

The BMR is the amount of calorie that you burn while you rest.

Once you find out how much calories your need per day, all you need to do to start to lose weight is consume 500 calories less than your daily calorie requirement.

Below is an explanation of the activity level that you would need for the BMR calculation.

Activity Level Key for BMR 

Sedentary = Means little or no exercise

Light Activity mean = 1 - 3 days a week

Moderate exercise =  3 - 5 days a week

Hard exercise = 6 - 7 days a week

High Activity level or active job = twice or more times a day

Understanding Basal Metabolic Calculation and the bmr calculator

There are different variable that are used for the BMR calculator. The units that are use are  age, gender, weight and height. These factors are used to determine your resting BMR which also include your activity level that will give you a number on how much calorie that you will need consume per day. Now you are wondering why and how these variables are needed to get the BMR.

The Age plays a role, as we age our metabolic rate drop this is not fair but it’s true for people over 40. Gender also plays a factor in the calculation.

Now you’re asking why would that play a factor, well men tend to have more lean muscle than women and that being said have a higher metabolic rate.

Now the last part that play a role is body surface for BMR calculator for diabetics.  That’s why you need to enter your weight and height. The more body surface that you have the more calorie that you burn through your basal metabolic rate.


Harris-Benedict Formula

Now the BMR Calculator for Diabetics uses a calculation called  Harris-Benedict Formula to determine the results. Please note: The example below uses kilograms for weight and cementers for height, but right below I will give a formula to convert the answer from Metric to Imperial.

Men:  66 + (13.7 x weight) + (5 x height) - (6.8 x age in years)

Women: 655 + (9.6 x weight) + (1.8 x height) - (4.7 x age in years)

Use the formula below to convert Metric to Imperial conversion

1 inch = 2.54 cm 

Example, if you are 5’3” (or 63”), then you height in cm equals 63 inches x 2.54 cm = 160 cm

1 pound = .45 kg (1 kg = 2.2 pounds so 1 pound divided by 2.2 kg equals .45)

Example, if you weight 160 pounds, then your weight in kg equals 160 lbs x .45 kg = 72 kg

So, if you are a 40 year old female weighing 150 pounds at 5’3” (or 63 inches), your calculation would be;

655 + (9.6 x [150 lbs x .45 kg]) + (1.8 x [63 inches x 2.54 cm]) – (4.7 x 40)

655 + (9.6 x 68 kg) + (1.8 x 160 cm) – (188)

655 + 653 + 288 – 188 = 1408 calories/day


Activity Factor

The weight loss calculator uses the calculation from the BMR Calculator and then factor in the activity level.  This will give you the calorie that you would need to exercise , lose weight and control your blood sugar.

The reason you need to understand the activity factor for this BMR calculator you want to make sure that you consume enough calories while doing exercise. By using the activity level in the weight loss calculators for diabetics you will get the correct amount of calorie that you need to sustain and/or lose weight.

Below is what is used to factor in the activity level.


Sedentary 

BMR x 1.2

no or little exercise

Lightly active

BMR x 1.375

light exercise 1 - 3 days/week

Moderately active

BMR x 1.55

mod. exercise/sports 3 - 5 days/week

Very active

BMR x 1.725

hard exercise/sports 6 - 7 days/week

Extremely active

BMR x 1.9

hard daily exercise/sports plus physical job or exercise 2x a day


Example:

If you BMR is 1408 depending of your activity level your daily calorie needs to maintain your weight would be as follows:

  • Sedentary = 1408 x 1.2 = 1690
  • Lightly active = 1408 x 1.375 = 1936
  • Moderately active = 1408 x 1.55 = 2182
  • Very active = 1408 x 1.725 = 2429
  • Extremely active = 1408 x 1.9 = 2675
