The system and method includes providing a web site where a candidate can access and answer a questionnaire. The password for accessing the website is provided by a health care provider to whom the candidate has consulted regarding weight loss therapies. The information received from the candidate is sent to a database network site where the information is analyzed to predict a weight loss outcome or expected outcome for the candidate for a weight loss therapy.
