Clinically proven may mean virtually anything... including nothing. A "clinically proven" statement in advertising is an effective sales pitch, usually a vague claim that requires no hard evidence and isn't easy to disprove. As long as the mandatory "These statements have not been evaluated by the FDA (...)" disclaimer is on the label, it's not necessary to have competent and reliable scientific evidence to back it up.
When used along a sensible diet and exercise program, our new eggplant extract is clinically proven to promote weight loss!
