New research reveals that patients who come off popular slimming jabs like Wegovy and Mounjaro may regain reduced body mass much more quickly than those who halt traditional lifestyle plans.
Research printed in a prominent medical journal points out that while obese people can lose substantial amounts of their body weight while on the medication, the weight is regained at an estimated rate of 0.8 kg per month upon discontinuation.
"Individuals purchasing these drugs must be cognizant of the risk of fast weight regain when the medication ends," warns researcher Dr. Susan Jebb.
This pace of recovery means a return to pre-treatment weight in about one and a half years.
Comparing Treatments
The analysis, which looked at dozens of studies involving thousands of participants, compared the outcomes of GLP-1 agonists with older methods.
Researchers point out that individuals who lose weight through diet and exercise generally experience a less rapid creep back—around 100 grams monthly—post-intervention.
Explaining the Fast Rebound
Doctors propose the way of the drugs explains the accelerated regain.
GLP-1 drugs copy a body's own chemical called glucagon-like peptide-1, which moderates appetite.
"Artificially providing GLP-1 levels several times higher than the body's typical production might result in the system to produce less of its own natural hormone, and could diminish responsiveness to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Stopping of this medication results in appetite is no longer kept in check, making binge eating much more probable."
An Ongoing Condition?
Health authorities suggest the injections for people with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
A number of clinicians argue that, given the high risk of weight regain, the treatment might need to be ongoing.
This perspective is reinforced by pharmaceutical companies, who state that the results "underscore the chronic nature of excess weight," comparing it to managing diseases like diabetes.
User Accounts
Users who have discontinued the jabs explain a intense resurgence of hunger.
"It felt as if a trigger flipping and you're instantly starving," described one woman.
This difficulty is worsened if individuals have not established permanent lifestyle or habit modifications during therapy.
Widespread Interest
Survey data show that millions of adults in the UK have tried these injections in the last 12 months, with interest being substantial.
- Use is higher among females compared to males.
- The middle-aged age group shows the highest usage rates.
- A large proportion access the medications through private prescriptions rather than the NHS.
In conclusion, researchers emphasize that while these medications are potent agents for weight loss, they are not a magic solution and long-term success relies on ongoing behavioural support.
