A recent study suggests that individuals who stop using blockbuster slimming jabs like Mounjaro or Wegovy may regain shed pounds at a significantly accelerated pace than those who halt conventional lifestyle regimens.
Research printed in a major medical journal points out that while obese individuals frequently drop about a fifth of their body weight while undergoing treatment, the mass is regained at an estimated rate of 0.8 kg per month after stopping.
"People buying such drugs must be informed of the risk of rapid weight regain when the therapy ends," cautioned lead investigator Dr. Susan Jebb.
Such speed of recovery implies a reversion to original mass in about one and a half years.
Weighing Therapies
The research, which looked at 37 of trials involving thousands of participants, contrasted the outcomes of GLP-1 agonists with other pills.
Researchers point out that individuals who shed pounds through lifestyle changes alone usually see a slower creep back—around 100 grams monthly—post-intervention.
Explaining the Rapid Rebound
Nutrition scientists suggest the way of the injections is key to understanding the amplified regain.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which controls feelings of fullness.
"Artificially providing the hormone levels far above than normal may cause the system to generate a reduced amount of its endogenous hormone, and could diminish responsiveness to its effects," noted Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this hormone supplement results in appetite is unsuppressed, making binge eating much more probable."
A Chronic Issue?
Health authorities advise the jabs for individuals with weight-linked health risks, alongside prescribed diet and exercise modifications.
Professionals say that, due to the significant potential of relapse, the treatment is often life-long.
This view is reinforced by pharmaceutical companies, who note that the findings "underscore the chronic nature of obesity," similar to managing conditions like high blood pressure.
User Accounts
Individuals who have come off the jabs report a intense return of appetite.
"It was like something activating and I was suddenly ravenous," described an individual.
This difficulty is worsened if users have not adopted lasting lifestyle or habit modifications during therapy.
Widespread Interest
Survey data show that millions of people in the UK have used these injections in the last 12 months, with interest continuing to grow.
- Use is greater among females compared to men.
- The middle-aged age group shows the highest usage rates.
- A large proportion access the drugs through private healthcare rather than the NHS.
Finally, clinicians stress that while GLP-1 drugs are effective tools for weight loss, they are not a permanent solution and long-term success hinges on integrated lifestyle changes.
