But scientists have warned that the game-changing injections could bizarrely affect people's behaviour, causing them to act recklessly and engage in risky sex or gambling . Skinny jabs like Wegovy and Mounjaro - as well as diabetes medication Ozempic - work by mimicking a hormone produced naturally by your gut when you eat food, to slow digestion, dull hunger pangs and shed body weight.

Its authors - Professor Raymond Playford, from the University of West London, and Professor Martin Deahl, from the Institute of Psychiatry - said patients ought to be warned about these bizarre side effects and cautioned against making life-changing decisions rashly. Prof Playford, an expert in molecular medicine, told .
