People who stop using the weight-loss jab Mounjaro not only tend to regain weight, but experience a reversal in other health improvements too, research suggests.

Mounjaro, which contains the active ingredient tirzepatide, has become a popular medication for weight loss, with studies suggesting that it can help people lose an average of 20% of their body weight after 72 weeks of treatment.
