Fresh analysis indicates that individuals who come off blockbuster GLP-1 drugs like Wegovy and Mounjaro tend to recover lost weight much more quickly than those who halt conventional diet and exercise plans.
Published data in a leading medical journal demonstrates that while overweight people frequently drop a large proportion of their body weight while on the medication, the mass returns at an average rate of nearly a kilo each month after stopping.
"People buying such medications must be informed of the potential of quick rebound weight gain when the treatment ends," stated researcher Dr. Susan Jebb.
This pace of regain means a reversion to starting weight within about 18 months.
Comparing Treatments
The research, which reviewed 37 of trials involving thousands of participants, contrasted the results of GLP-1 agonists with conventional dieting.
Scientists emphasize that people who shed pounds through diet and exercise typically have a more gradual creep back—perhaps 100 grams monthly—post-intervention.
Explaining the Fast Regain
Experts propose the way of the drugs accounts for the heightened regain.
GLP-1 drugs copy a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Long-term administration of the hormone levels far above than the body's typical production may cause the body to produce less of its endogenous hormone, and could diminish responsiveness to its effects," noted Dr. Adam Collins, a nutrition specialist.
"Stopping of this GLP-1 'fix' results in hunger is no longer kept in check, making overeating much more probable."
A Chronic Condition?
Medical guidelines advise the jabs for individuals with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
A number of clinicians contend that, considering the likelihood of weight regain, the therapy should be considered ongoing.
This perspective is supported by pharmaceutical companies, who state that the results "emphasize the persistent character of obesity," similar to managing conditions like diabetes.
Patient Accounts
People who have come off the medication describe a powerful return of cravings.
"I experienced a trigger that goes on and you're instantly starving," described one woman.
This challenge is worsened if patients have not adopted lasting lifestyle or habit modifications during treatment.
Significant Use
Figures show that a significant number of adults in the UK have tried these injections in the past year, with desire being substantial.
- Use is more common among women compared to males.
- The middle-aged age group shows the greatest level of interest.
- A large proportion access the drugs through private prescriptions rather than the NHS.
In conclusion, experts caution that while GLP-1 drugs are powerful tools for shedding pounds, they are not a permanent cure and lasting health benefits hinges on ongoing behavioural support.
