New research reveals that people who come off blockbuster GLP-1 drugs like Wegovy and Mounjaro can put back on shed pounds far faster than those who stop conventional lifestyle programs.
Research printed in a prominent medical journal shows that while overweight individuals often shed substantial amounts of their body weight while on the medication, the mass is regained at an average rate of 0.8 kg per month after stopping.
"Users using such drugs must be informed of the potential of quick weight regain when the therapy is stopped," stated researcher Dr. Susan Jebb.
This pace of recovery implies a return to pre-treatment mass within about a year and a half.
Analyzing Treatments
The research, which reviewed 37 of studies involving thousands of participants, compared the outcomes of these new drugs with other pills.
Scientists point out that people who lose weight through diet and exercise usually see a less rapid creep back—around 100 grams monthly—after stopping.
Understanding the Fast Rebound
Experts believe the mode of action of the drugs is key to understanding the heightened regain.
The injections copy a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Artificially providing GLP-1 levels far above than the body's typical production could lead to the system to generate a reduced amount of its endogenous hormone, and may also lessen responsiveness to its effects," noted Dr. Adam Collins, a nutrition expert.
"Discontinuation of this GLP-1 'fix' leads to hunger is unsuppressed, making excessive eating a significant risk."
A Lifelong Issue?
Health authorities suggest the injections for people with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
Professionals contend that, considering the likelihood of weight regain, the treatment might need to be long-term.
This opinion is reinforced by drug manufacturers, who note that the findings "highlight the long-term nature of obesity," similar to managing conditions like hypertension.
User Experiences
People who have come off the jabs report a intense resurgence of appetite.
"I experienced a switch flipping and you're instantly ravenous," described a patient.
The struggle is compounded if patients have not adopted permanent lifestyle or habit modifications during treatment.
Growing Adoption
Survey data indicate that millions of adults in the UK have used weight-loss jabs in the last 12 months, with desire remaining high.
- Use is higher among women compared to males.
- The middle-aged age group shows the greatest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
In conclusion, experts caution that while GLP-1 drugs are effective agents for weight loss, they are not a permanent solution and maintained weight loss hinges on integrated lifestyle management.
