Fresh analysis suggests that people who discontinue new slimming jabs like Mounjaro or Wegovy may regain lost weight much more quickly than those who end traditional diet and exercise programs.
Published data in a major health publication demonstrates that while obese people can lose about a fifth of their body weight while using the jabs, the mass is regained at an average rate of 0.8 kg per month once they quit.
"Users using these drugs should be aware of the potential of fast rebound weight gain when the medication concludes," warns expert Dr. Susan Jebb.
This pace of recovery means a reversion to pre-treatment mass within about one and a half years.
Comparing Therapies
The research, which looked at 37 of studies involving thousands of participants, contrasted the results of these new drugs with older methods.
Researchers note that individuals who shed pounds through diet and exercise usually experience a less rapid weight regain—approximately 0.1 kg a month—after stopping.
Explaining the Rapid Regain
Experts propose the way of the injections explains the accelerated regain.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of the hormone concentrations far above than normal may cause the system to produce less of its own natural hormone, and may also reduce sensitivity to its actions," noted Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this GLP-1 'fix' leads to appetite is uncontrolled, making binge eating a significant risk."
A Chronic Condition?
Medical guidelines suggest the jabs for people with obesity-related health risks, accompanied by recommended lifestyle changes.
A number of clinicians say that, given the significant potential of relapse, the treatment might need to be long-term.
This view is reinforced by drug manufacturers, who say that the results "underscore the chronic nature of excess weight," comparing it to managing diseases like diabetes.
Patient Experiences
Users who have discontinued the jabs describe a intense resurgence of cravings.
"It felt as if a trigger flipping and you're instantly extremely hungry," recalled one woman.
This challenge is worsened if patients have not established sustainable dietary or behavioural changes during treatment.
Growing Adoption
Recent estimates indicate that millions of adults in the UK have used weight-loss jabs in the last 12 months, with demand remaining high.
- Adoption is greater among women than men.
- The middle-aged demographic shows the greatest usage rates.
- A large proportion access the medications through private prescriptions rather than the NHS.
In conclusion, clinicians stress that while the jabs are powerful agents for weight loss, they are not a magic solution and long-term success relies on combined lifestyle support.
