Example Problem

How to calculate weight loss inches?

First, determine the initial and final size of your waist. For this example, the initial size was 36 inches and the final size was 32 inches. Subtracting these values yields a total of 4 inches.

Next, determine the initial and final size of your neck. In this case, these are measured to be 12 and 11 inches respectively. Subtracting these values yields 1 inch.

Next, determine the initial and final size of your chest. For this example person, these were 45 and 43 inches respectively. Subtracting yields 2 inches here.

Next, measure the initial and final size of your thigh. For this example, these values were 25 and 23 which yields a net loss of 2 inches.

Finally, sum all of the values together to yield the total sum of weight loss inches.

= 4+ 1 + 2 + 2

= 9 inches of weight loss total
