A recent study reveals that patients who stop using blockbuster weight-loss injections like Wegovy and Mounjaro tend to recover lost weight far faster than those who halt conventional lifestyle regimens.
Findings released in a prominent medical journal demonstrates that while obese individuals can lose substantial amounts of their total mass while using the jabs, the mass is regained at an average rate of nearly a kilo each month after stopping.
"Individuals using such medications need to be informed of the danger of rapid weight regain when the medication ends," cautioned expert Dr. Susan Jebb.
That rate of recovery implies a return to starting mass within about 18 months.
Comparing Therapies
The study, which reviewed dozens of studies involving thousands of participants, compared the outcomes of these new drugs with other pills.
Researchers note that people who shed pounds through diet and exercise usually see a slower creep back—perhaps 0.1 kg a month—post-intervention.
Understanding the Rapid Rebound
Nutrition scientists believe the mechanism of the jabs explains the accelerated weight return.
These medications imitate a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 levels far above than normal 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 specialist.
"Stopping of this GLP-1 'fix' leads to appetite is unsuppressed, making excessive eating much more probable."
A Chronic Issue?
Medical guidelines recommend the jabs for people with obesity-related health risks, accompanied by prescribed lifestyle changes.
A number of clinicians contend that, considering the likelihood of weight regain, the therapy might need to be long-term.
This view is supported by drug manufacturers, who say that the results "emphasize the long-term nature of excess weight," akin to managing conditions like hypertension.
Patient Experiences
People who have discontinued the jabs explain a intense return of cravings.
"It felt as if something flipping and you're instantly ravenous," described a patient.
This difficulty is worsened if patients have not adopted permanent dietary or behavioural changes during therapy.
Widespread Use
Recent estimates show that millions of adults in the UK have used weight-loss jabs in the last 12 months, with desire continuing to grow.
- Adoption is greater among females compared to men.
- The middle-aged demographic shows the greatest usage rates.
- Many access the medications through private healthcare rather than public health services.
Ultimately, experts stress that while these medications are potent tools for weight loss, they are not a standalone fix and maintained weight loss hinges on ongoing behavioural management.
