- Individuals using GLP-1 obesity medications such as Mounjaro or Wegovy are likely to regain almost two-thirds of the weight they lost within a year of stopping the drugs.
- A study by the University of Cambridge, involving over 3,200 people, found that patients regained 60 per cent of lost weight after 52 weeks off the jabs.
- While most weight is regained, researchers suggest approximately 25 per cent of the initial weight loss may be sustained in the long term.
- Experts caution that if the regained weight is predominantly fat, individuals could be “worse off than before” they started treatment, potentially impacting their health.
- Researchers are calling for future trials to investigate the composition of weight loss and for improved prescribing guidelines, as current advice is inconsistent regarding post-treatment weight regain.
