Fresh analysis reveals that patients who come off new GLP-1 drugs like Mounjaro or Wegovy can put back on reduced body mass much more quickly than those who halt conventional lifestyle plans.
Findings released in a leading medical journal points out that while obese individuals frequently drop a large proportion of their total mass while using the jabs, the weight returns at an average rate of nearly a kilo each month after stopping.
"People using such medications need to be aware of the potential of fast rebound weight gain when the therapy is stopped," warns expert Dr. Susan Jebb.
That rate of regain suggests a reversion to starting weight in about one and a half years.
Comparing Treatments
The study, which looked at dozens of trials involving thousands of participants, compared the effects of GLP-1 agonists with other pills.
The team point out that individuals who shed pounds through lifestyle changes alone typically experience a less rapid creep back—around 0.1 kg a month—post-intervention.
Explaining the Rapid Rebound
Experts believe the way of the drugs explains the heightened weight return.
These medications copy a natural hormone called glucagon-like peptide-1, which controls feelings of fullness.
"Sustained high doses of GLP-1 levels far above than normal could lead to the system to generate a reduced amount of its endogenous hormone, and may also diminish responsiveness to its actions," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement means hunger is uncontrolled, making excessive eating far more likely."
A Chronic Condition?
Medical guidelines advise the jabs for people with weight-linked health risks, alongside recommended diet and exercise modifications.
A number of clinicians argue that, given the high risk of weight regain, the therapy might need to be long-term.
This perspective is supported by pharmaceutical companies, who note that the results "emphasize the persistent nature of obesity," comparing it to managing conditions like high blood pressure.
Patient Accounts
Individuals who have come off the jabs describe a sudden resurgence of appetite.
"I experienced a switch flipping and you're instantly ravenous," said an individual.
This challenge is exacerbated if individuals have not adopted sustainable dietary or behavioural modifications during treatment.
Growing Interest
Survey data indicate that a significant number of adults in the UK have used weight-loss jabs in the past year, with demand being substantial.
- Use is greater among women than men.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
In conclusion, clinicians stress that while the jabs are potent tools for shedding pounds, they are not a magic cure and maintained weight loss relies on integrated behavioural management.
