The waist-to-height ratio is a simple indicator of overall health for men and women. If your waist-to-height ratio is higher or lower than the recommended range, it can indicate a shorter lifespan, and risks of severe illnesses.1
Waist-to-height measurements can also be used to roughly predict your likelihood of testosterone deficiency.2
The rule is, ‘keep your waistline less than half your height’
You can do this simple measurement with a piece of string. Cut a piece of string to the same length as your height, then fold it in half and wrap it around your waist. If your waist-to-height ratio is healthy there should be a small amount of excess string.
