A recent study suggests that patients who stop using blockbuster weight-loss injections like Mounjaro or Wegovy tend to recover shed pounds much more quickly than those who end traditional lifestyle plans.
Published data in a prominent medical journal demonstrates that while obese individuals frequently drop about a fifth of their body weight while undergoing treatment, the weight comes back at an estimated rate of 0.8 kg per month once they quit.
"People purchasing these medications must be cognizant of the potential of quick weight regain when the treatment concludes," stated lead investigator Dr. Susan Jebb.
Such speed of recovery implies a return to original mass in about 18 months.
Weighing Approaches
The research, which reviewed dozens of studies involving over 9,000 of participants, compared the effects of the injectable medications with older methods.
Researchers note that individuals who shed pounds through lifestyle changes alone usually have a more gradual creep back—approximately 0.1 kg a month—post-intervention.
The Reason for the Fast Rebound
Experts suggest the way of the injections explains the heightened rebound.
GLP-1 drugs mimic a natural hormone called GLP-1, which helps regulate hunger.
"Long-term administration of GLP-1 concentrations several times higher than normal may cause the body to generate a reduced amount of its endogenous hormone, and may also reduce responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this hormone supplement leads to appetite is unsuppressed, making binge eating a significant risk."
An Ongoing Issue?
The NHS advise the jabs for individuals with obesity-related medical conditions, alongside recommended diet and exercise modifications.
Many experts contend that, considering the significant potential of relapse, the therapy is often long-term.
This opinion is echoed by drug manufacturers, who state that the findings "highlight the long-term nature of excess weight," akin to managing conditions like hypertension.
User Accounts
Users who have stopped the medication describe a intense return of hunger.
"It felt as if a trigger flipping and I was suddenly starving," described one woman.
This challenge is exacerbated if users have not developed permanent dietary or behavioural changes during treatment.
Significant Use
Survey data show that millions of people in the UK have used these injections in the past year, with desire being substantial.
- Adoption is greater among women compared to males.
- The 40s and 50s age group shows the greatest level of interest.
- Many access the drugs through private prescriptions rather than public health services.
In conclusion, clinicians emphasize that while the jabs are potent tools for shedding pounds, they are not a standalone cure and maintained weight loss relies on integrated lifestyle support.
