A recent study suggests that individuals who discontinue popular slimming jabs 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 shows that while overweight people can lose substantial amounts of their total mass while on the medication, the mass returns at an estimated rate of 0.8 kg per month once they quit.
"Users using these treatments must be informed of the danger of rapid weight regain when the treatment is stopped," warns lead investigator Dr. Susan Jebb.
Such speed of recovery implies a reversion to original weight within about 18 months.
Analyzing Treatments
The research, which examined dozens of studies involving over 9,000 of patients, contrasted the outcomes of the injectable medications with other pills.
Researchers note that individuals who lose weight through lifestyle changes alone usually have a less rapid creep back—approximately 0.1 kg a month—post-intervention.
Understanding the Quick Regain
Experts believe the way of the injections explains the amplified regain.
GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Sustained high doses of the hormone concentrations far above than the body's typical production might result in the system to generate a reduced amount of its endogenous hormone, and could diminish sensitivity to its actions," explained Dr. Adam Collins, a dietetics expert.
"Stopping of this medication leads to hunger is unsuppressed, making overeating a significant risk."
A Chronic Condition?
Health authorities recommend the jabs for individuals with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
Professionals say that, given the likelihood of weight regain, the treatment should be considered long-term.
This view is echoed by pharmaceutical companies, who note that the results "highlight the long-term nature of excess weight," comparing it to managing diseases like high blood pressure.
User Testimonies
People who have come off the jabs explain a powerful return of appetite.
"It felt as if something that goes on and I was suddenly extremely hungry," said an individual.
This difficulty is compounded if patients have not adopted permanent dietary or behavioural modifications during treatment.
Widespread Interest
Recent estimates suggest that millions of adults in the UK have used these injections in the last 12 months, with interest remaining high.
- Use is greater among women than men.
- The 40s and 50s age group shows the greatest usage rates.
- Many obtain the drugs through private prescriptions rather than the NHS.
Ultimately, clinicians stress that while GLP-1 drugs are potent agents for shedding pounds, they are not a permanent solution and maintained weight loss hinges on combined lifestyle changes.
