New research reveals that individuals who discontinue popular weight-loss injections like Mounjaro or Wegovy may regain lost weight far faster than those who halt conventional diet and exercise regimens.
Research printed in a leading medical journal demonstrates that while obese individuals can lose a large proportion of their body weight while undergoing treatment, the weight is regained at an estimated rate of 0.8 kg per month once they quit.
"Individuals purchasing these medications must be aware of the risk of rapid weight regain when the therapy concludes," cautioned expert Dr. Susan Jebb.
That rate of recovery implies a reversion to pre-treatment mass within about 18 months.
Weighing Therapies
The research, which examined dozens of studies involving over 9,000 of patients, contrasted the outcomes of GLP-1 agonists with conventional dieting.
Scientists point out that individuals who lose weight through lifestyle changes alone usually have a more gradual weight regain—approximately 0.1 kg a month—after stopping.
Explaining the Quick Regain
Doctors believe the mode of action of the injections accounts for the heightened weight return.
The injections imitate a natural hormone called glucagon-like peptide-1, which moderates appetite.
"Sustained high doses of GLP-1 levels far above than the body's typical production may cause the body to generate a reduced amount of its own natural GLP-1, and may also lessen responsiveness to its actions," noted Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this GLP-1 'fix' means appetite is uncontrolled, making binge eating a significant risk."
An Ongoing Condition?
Health authorities suggest the injections for individuals with obesity-related health risks, alongside recommended diet and exercise modifications.
A number of clinicians argue that, due to the high risk of relapse, the therapy is often life-long.
This view is reinforced by pharmaceutical companies, who state that the results "highlight the persistent nature of excess weight," akin to managing conditions like high blood pressure.
Patient Testimonies
Individuals who have stopped the medication explain a powerful return of cravings.
"I experienced a trigger activating and I was suddenly extremely hungry," said a patient.
This difficulty is worsened if patients have not established lasting dietary or behavioural modifications during treatment.
Significant Use
Figures show that a significant number of people in the UK have tried these injections in the past year, with demand being substantial.
- Use is more common among females compared to males.
- The middle-aged demographic shows the highest usage rates.
- Many access the drugs through private prescriptions rather than the NHS.
In conclusion, clinicians stress that while these medications are potent agents for shedding pounds, they are not a standalone solution and maintained weight loss likely depends on ongoing behavioural support.
