Points Plus Allowance Calculation

Total Energy Expenditure (TEE) and Adjusted TEE

The first step in the points plus allowance calculation is determining the TEE.

TEE is the total energy expenditure.

This step will use your current age, weight (in kilograms) and height (in meters).

There is a separate formula for men versus women. 

The PA in the formula represents the Physical Activity level.

For purposes of the TEE, the activity level for men is set at 1.12 and women at 1.14. The formula assumes a low activity level for all in the below formula.

For men, the formula is;

TEE = 864 - (9.72 x age) + (PA x ((14.2 x wgt) + (503 x Ht))

For women, the forumla is;

TEE = 387 - (7.31 x age) + (PA x ((10.9 x wgt) + (660.7 x Ht))

Let's take an example for this first calculation. For instance, a 45 year old man weighing 245 lbs and is 5'9" tall, the first step would be to convert the lbs to kg and total inches to meters. 

1 pound = 0.45359237. To simplify this we will use 0.454.

1 inch = 0.0254 meters.

So to begin this example, let's first convert the weight and height.

Weight
245lb x 0.454 = 111.23 kg

To convert the height to meters, you must first convert the feet to inches. To do this simply multiply 12 by the feet.

Then add in the additional inches to get the total. Once you have the total, multiply it by the 0.254 to get the meters.

Height
5ft x 12 + 9inches = 69 inches
69 x .0254 = 1.75 meters

Now that this conversion is done, we can apply the TEE formula. Remember to always complete the multiplication and division steps in a formula prior to the addition and subtraction steps.

Basically, do the math in the parentheses first then finish with the simple addition and subtraction steps. For this example, the formula would be;

TEE = 864 - (9.72 x 45) + (1.12 x (14.2 x 111.23) + (503 x 1.75)

In the above formula, 45 is the age, 1.12 is the activity level for men, 111.23 is his weight in kg and 1.75 is the height in meters. Let's complete the formula in steps. Below is the next step, using the age, wgt and ht to complete those portions.

TEE = 864 - 437.4 + 1.12 x (1579.47 + 880.25)

Now let's do the next step adding together the results of the weight and height (the piece in the parentheses).

TEE = 864 - 437.4 + 1.12 x 2459.72

Now we can complete the last step, remembering to do the multiplication first then the addition and subtraction pieces.

TEE = 864 - 437.4 + 2754.89 = 3181.49

So the TEE for this example is 3181.49. We are ready for the next formula.

Adjusted Total Energy Expenditure (ATEE) - Step 2

The above formula does not get you to the daily allowance.

You need to take the results from this formula and then calculate the Adjusted Total Energy Expenditure (ATEE).

The ATEE formula is as follows;

ATEE = TEE - (TEE x .10) + 200.

Per the Europeon Patent Office website "The published methods assume a 10 percent conversion costregardless of the types and amounts of nutrients consumed; consequently, TEE is adjusted by subtracting 10 percent of the calculated TEE."

Additionally, foods are given a zero energy content (our freebie veggies and fruits), however these foods do in fact contain an energy content.

So, the TEE is also adjusted for these items which generally fall within a range of 150 to 250 kilograms. For purposes of the ATEE, this amount is normalized using 200 kg.

So for our example, we will use the TEE of 3181.49 as calculated in the first step. The ATEE formula for this example would be;

ATEE = 3181.49 - (3181.49 x .10) + 200

ATEE = 3181.49 - 318.15 + 200 = 3063.34

So this man's ATEE would be 3063.34. We are not done yet. Now it's time for the next step and the next formula.
