The range your body defends
There is no test that pinpoints a set point. Your own history is the nearest substitute: the weights you have held for a year or more are the strongest available clue to what your body defends now.
The short answer
Your body regulates weight around a defended range rather than a single numberC-III-12. This tool estimates where yours currently sits, using the weights you have actually sustained, and explains what that estimate means. It is an educational estimate, not a measurement.

For education only. Not medical advice, diagnosis, or treatment, and not a substitute for care from a qualified professional. There is no test that pinpoints a personal set pointC-III-12. If you're struggling with eating or body image, please talk to a healthcare provider or a support line.
Where this sits in the science
The band this tool returns is a reading of your sustained weights, not a measured value. Its width comes from a rule of thumb used in obesity research for a defended range, and that choice has not been validated in a published studyC-III-12. Why the weight you defend keeps rising sets out the evidence the estimate rests on, including the parts that are weaker than the confident version.
