AI fitness instructors make misleading claims about rapid results

Misleading fitness adverts featuring AI-generated instructors making exaggerated claims about rapid body transformations are breaching UK advertising rules. The AI characters often claim to have achieved scientifically implausible results, such as looking 20 years younger or losing significant weight in weeks, to sell app subscriptions. Many adverts fail to disclose that the instructors are not real. Experts warn these unrealistic claims create false hope and damaging expectations, while real fitness professionals highlight the impossibility of such rapid changes and the potential harm to users' confidence and health.
