Fresh analysis indicates that individuals who come off popular slimming jabs like Mounjaro or Wegovy tend to recover lost weight much more quickly than those who stop traditional diet and exercise regimens.
Published data in a leading medical journal points out that while obese individuals frequently drop a large proportion of their total mass while undergoing treatment, the mass is regained at an estimated rate of nearly a kilo each month upon discontinuation.
"Individuals purchasing such drugs must be informed of the potential of quick weight regain when the therapy concludes," cautioned lead investigator Dr. Susan Jebb.
That rate of regain suggests a reversion to original weight within about 18 months.
Weighing Approaches
The research, which looked at 37 of studies involving over 9,000 of participants, contrasted the outcomes of these new drugs with other pills.
Scientists emphasize that people who shed pounds through dieting typically have a more gradual creep back—approximately 100 grams monthly—once they finish.
Understanding the Quick Regain
Nutrition scientists propose the mechanism of the injections accounts for the heightened rebound.
The injections imitate a natural hormone called glucagon-like peptide-1, which moderates feelings of fullness.
"Artificially providing GLP-1 concentrations several times higher than the body's typical production may cause the system to generate a reduced amount of its own natural hormone, and may also lessen responsiveness to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this hormone supplement results in appetite is no longer kept in check, making excessive eating far more likely."
A Lifelong Disease?
The NHS suggest the jabs for people with weight-linked medical conditions, alongside recommended lifestyle changes.
Many experts argue that, given the likelihood of relapse, the treatment is often ongoing.
This perspective is supported by pharmaceutical companies, who note that the findings "emphasize the persistent character of excess weight," similar to managing conditions like diabetes.
User Experiences
People who have discontinued the jabs report a sudden return of appetite.
"I experienced a trigger that goes on and you're instantly ravenous," described a patient.
This challenge is compounded if users have not adopted lasting lifestyle or habit modifications during therapy.
Significant Adoption
Figures show that millions of adults in the UK have tried these injections in the last 12 months, with demand continuing to grow.
- Adoption is more common among women than men.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion obtain the medications through private prescriptions rather than the NHS.
Ultimately, clinicians stress that while the jabs are powerful agents for shedding pounds, they are not a magic fix and maintained weight loss likely depends on ongoing lifestyle changes.
