Slimmers who come off weight-loss injections such as Mounjaro or Wegovy can regain their lost pounds four times faster than those who stop conventional dieting and exercising, new research suggests.
Data published in the British Medical Journal suggests overweight people shed large amounts when using jabs - about a fifth of their body weight - but once they quit they regain 0.8 kg every month, on average.
That means they return to their pre-treatment weight in a year and a half.
"People buying these need to be aware of the risk of fast weight regain when the treatment ends," warns investigator Dr Susan Jebb, from Oxford University.
She stressed that the findings come from medical trials rather than real life and more studies of the longer-term effects of new slimming jabs would be helpful.
