New research indicates that people who discontinue blockbuster GLP-1 drugs like Wegovy and Mounjaro can put back on lost weight at a significantly accelerated pace than those who halt conventional diet and exercise programs.
Research printed in a leading health publication shows that while overweight people often shed a large proportion of their body weight while using the jabs, the weight is regained at an estimated rate of nearly a kilo each month after stopping.
"Individuals purchasing such drugs must be informed of the potential of fast weight regain when the medication concludes," cautioned expert Dr. Susan Jebb.
Such speed of recovery suggests a return to pre-treatment weight within about a year and a half.
Comparing Therapies
The research, which examined dozens of trials involving over 9,000 of participants, contrasted the outcomes of GLP-1 agonists with older methods.
Researchers emphasize that individuals who shed pounds through diet and exercise usually have a slower creep back—perhaps 100 grams monthly—post-intervention.
Understanding the Rapid Regain
Doctors suggest the mechanism of the injections accounts for the heightened regain.
The injections mimic a natural hormone called GLP-1, which helps regulate hunger.
"Artificially providing GLP-1 concentrations far above than the body's typical production could lead to the body to produce less of its own natural hormone, and may also diminish responsiveness to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this medication leads to appetite is uncontrolled, making excessive eating far more likely."
A Lifelong Issue?
The NHS suggest the jabs for individuals with obesity-related health risks, alongside recommended diet and exercise modifications.
A number of clinicians say that, due to the likelihood of weight regain, the therapy is often ongoing.
This view is supported by drug manufacturers, who state that the findings "emphasize the chronic nature of excess weight," similar to managing diseases like hypertension.
User Accounts
Individuals who have discontinued the medication report a intense resurgence of appetite.
"It was like a switch activating and you become starving," said a patient.
This challenge is compounded if patients have not established sustainable dietary or behavioural changes during treatment.
Widespread Adoption
Recent estimates indicate that millions of people in the UK have used these injections in the last 12 months, with demand being substantial.
- Adoption is greater among females compared to men.
- The 40s and 50s age group shows the highest level of interest.
- Many access the drugs through private healthcare rather than the NHS.
In conclusion, experts caution that while these medications are potent tools for shedding pounds, they are not a magic cure and maintained weight loss hinges on combined lifestyle support.
