Fresh analysis indicates that patients who stop using blockbuster slimming jabs like Mounjaro or Wegovy can put back on shed pounds far faster than those who stop conventional lifestyle plans.
Published data in a prominent medical journal demonstrates that while obese individuals can lose substantial amounts of their total mass while on the medication, the mass is regained at an average rate of 0.8 kg per month after stopping.
"Individuals buying such treatments need to be cognizant of the danger of quick rebound weight gain when the medication is stopped," warns lead investigator Dr. Susan Jebb.
This pace of regain implies a return to pre-treatment weight within about 18 months.
Weighing Treatments
The research, which reviewed dozens of studies involving thousands of patients, contrasted the outcomes of the injectable medications with other pills.
The team note that people who shed pounds through diet and exercise generally have a more gradual weight regain—approximately 100 grams monthly—post-intervention.
Explaining the Fast Rebound
Experts believe the way of the drugs explains the amplified regain.
These medications imitate a natural hormone called GLP-1, which helps regulate hunger.
"Long-term administration of GLP-1 concentrations far above than normal may cause the system to generate a reduced amount of its own natural hormone, and could diminish sensitivity to its actions," noted Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this medication leads to hunger is no longer kept in check, making binge eating much more probable."
An Ongoing Issue?
Health authorities advise the jabs for people with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
Professionals argue that, due to the high risk of weight regain, the treatment is often long-term.
This opinion is supported by drug manufacturers, who state that the results "emphasize the persistent character of excess weight," comparing it to managing conditions like hypertension.
Patient Accounts
Individuals who have stopped the medication explain a intense return of appetite.
"I experienced a switch that goes on and you become extremely hungry," described a patient.
This challenge is exacerbated if patients have not adopted sustainable lifestyle or habit changes during therapy.
Significant Use
Survey data indicate that millions of people in the UK have used these injections in the past year, with desire being substantial.
- Use is greater among women compared to males.
- The middle-aged age group shows the greatest level of interest.
- Many obtain the drugs through private prescriptions rather than the NHS.
Ultimately, experts stress that while GLP-1 drugs are effective tools for weight loss, they are not a permanent cure and lasting health benefits relies on integrated behavioural changes.
