Fresh analysis reveals that people who discontinue blockbuster slimming jabs like Mounjaro or Wegovy tend to recover lost weight far faster than those who end conventional diet and exercise programs.
Published data in a major medical journal shows that while overweight people often shed about a fifth of their body weight while undergoing treatment, the mass comes back at an estimated rate of 0.8 kg per month upon discontinuation.
"Individuals using such drugs should be cognizant of the danger of quick rebound weight gain when the medication is stopped," warns researcher Dr. Susan Jebb.
Such speed of recovery suggests a return to pre-treatment weight in about 18 months.
Comparing Therapies
The research, which looked at 37 of studies involving over 9,000 of patients, compared the outcomes of the injectable medications with older methods.
Researchers note that people who lose weight through lifestyle changes alone typically see a slower weight regain—perhaps 100 grams monthly—once they finish.
Understanding the Rapid Rebound
Doctors believe the way of the injections accounts for the accelerated rebound.
These medications imitate a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Sustained high doses of the hormone levels far above than the body's typical production may cause the body to produce less of its own natural GLP-1, and could diminish sensitivity to its effects," said Dr. Adam Collins, a dietetics researcher.
"Stopping of this GLP-1 'fix' leads to hunger is no longer kept in check, making overeating much more probable."
An Ongoing Issue?
Health authorities advise the jabs for people with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
Professionals argue that, considering the significant potential of relapse, the therapy might need to be life-long.
This view is echoed by drug manufacturers, who state that the findings "underscore the persistent nature of excess weight," comparing it to managing conditions like hypertension.
User Testimonies
Users who have discontinued the medication explain a intense return of cravings.
"I experienced a switch flipping and you become ravenous," recalled a patient.
This challenge is exacerbated if individuals have not established lasting dietary or behavioural modifications during treatment.
Significant Interest
Survey data suggest that millions of people in the UK have tried weight-loss jabs in the past year, with desire continuing to grow.
- Use is greater among females than males.
- The middle-aged age group shows the greatest level of interest.
- Many access the drugs through private healthcare rather than the NHS.
Ultimately, clinicians stress that while GLP-1 drugs are powerful agents for shedding pounds, they are not a magic solution and lasting health benefits relies on combined behavioural management.
