A recent study suggests that patients who discontinue popular weight-loss injections like Wegovy and Mounjaro may regain reduced body mass much more quickly than those who stop conventional diet and exercise plans.
Research printed in a prominent health publication shows that while obese individuals often shed a large proportion of their body weight while undergoing treatment, the weight is regained at an average rate of 0.8 kg per month after stopping.
"Users buying these treatments need to be aware of the risk of fast rebound weight gain when the treatment is stopped," warns researcher Dr. Susan Jebb.
Such speed of regain suggests a reversion to pre-treatment mass in about a year and a half.
Comparing Therapies
The analysis, which examined dozens of studies involving thousands of participants, compared the effects of GLP-1 agonists with other pills.
Scientists emphasize that individuals who lose weight through lifestyle changes alone usually see a more gradual weight regain—perhaps 0.1 kg a month—after stopping.
Understanding the Fast Regain
Doctors believe the mode of action of the injections explains the accelerated rebound.
These medications imitate a body's own chemical called glucagon-like peptide-1, which controls hunger.
"Sustained high doses of the hormone levels several times higher than the body's typical production may cause the body to generate a reduced amount of its own natural GLP-1, and could lessen responsiveness to its effects," noted Dr. Adam Collins, a nutrition specialist.
"Stopping of this GLP-1 'fix' means appetite is no longer kept in check, making excessive eating a significant risk."
A Chronic Disease?
Health authorities suggest the jabs for people with weight-linked medical conditions, alongside prescribed lifestyle changes.
Professionals say that, considering the significant potential of relapse, the treatment might need to be life-long.
This view is reinforced by pharmaceutical companies, who say that the findings "underscore the chronic nature of obesity," akin to managing diseases like hypertension.
Patient Testimonies
Individuals who have stopped the medication report a powerful resurgence of hunger.
"It was like a switch that goes on and you become ravenous," said an individual.
This difficulty is compounded if individuals have not established lasting lifestyle or habit changes during therapy.
Widespread Adoption
Figures show that a significant number of adults in the UK have tried these injections in the past year, with interest being substantial.
- Use is higher among women compared to males.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion access the drugs through private healthcare rather than public health services.
In conclusion, experts caution that while the jabs are powerful tools for shedding pounds, they are not a standalone solution and lasting health benefits relies on ongoing behavioural management.
