The formula to calculate the Weight Loss Inches (WLI) is:
\[ \text{WLI} = \text{OS} - \text{FS} \]
Where:
Weight loss inches are defined as the sum total of all of the inches lost on body parts due to the effect of losing weight. This is typically measured on more than one body part and then summed together. The most common areas for measurement are the chest, waist, neck, and thigh.
Let's assume the following values:
Using the formula to calculate the Weight Loss Inches:
\[ \text{WLI} = 40 \text{ inches} - 35 \text{ inches} = 5 \text{ inches} \]
The Weight Loss Inches (WLI) is 5 inches.
