New research indicates that people who come off blockbuster weight-loss injections like Mounjaro or Wegovy may regain shed pounds far faster than those who end conventional lifestyle regimens.
Published data in a prominent health publication shows that while overweight individuals can lose substantial amounts of their total mass while undergoing treatment, the mass comes back at an estimated rate of 0.8 kg per month upon discontinuation.
"Users purchasing these medications must be informed of the risk of rapid weight regain when the therapy is stopped," cautioned lead investigator Dr. Susan Jebb.
That rate of regain means a return to starting mass within about 18 months.
Comparing Treatments
The study, which looked at dozens of studies involving over 9,000 of participants, compared the outcomes of the injectable medications with conventional dieting.
The team emphasize that individuals who shed pounds through lifestyle changes alone typically have a more gradual weight regain—around 0.1 kg a month—once they finish.
Understanding the Rapid Regain
Doctors suggest the way of the jabs explains the amplified regain.
These medications imitate a natural hormone called glucagon-like peptide-1, which controls hunger.
"Sustained high doses of the hormone concentrations far above than normal may cause the system to produce less of its endogenous GLP-1, and could lessen responsiveness to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this hormone supplement results in hunger is no longer kept in check, making binge eating far more likely."
A Chronic Condition?
Health authorities suggest the jabs for individuals with obesity-related medical conditions, alongside prescribed lifestyle changes.
Many experts contend that, given the likelihood of weight regain, the treatment should be considered ongoing.
This opinion is supported by drug manufacturers, who note that the findings "highlight the persistent character of excess weight," similar to managing diseases like hypertension.
Patient Accounts
Individuals who have stopped the jabs explain a intense resurgence of appetite.
"It felt as if a trigger flipping and I was suddenly starving," described one woman.
This challenge is exacerbated if individuals have not established permanent lifestyle or habit modifications during therapy.
Growing Interest
Recent estimates suggest that a significant number of adults in the UK have used weight-loss jabs in the last 12 months, with interest continuing to grow.
- Adoption is more common among women than men.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion access the drugs through private prescriptions rather than the NHS.
In conclusion, clinicians stress that while these medications are effective agents for shedding pounds, they are not a standalone solution and maintained weight loss relies on ongoing lifestyle changes.
