New research reveals that patients who stop using new weight-loss injections like Mounjaro or Wegovy may regain lost weight at a significantly accelerated pace than those who end conventional lifestyle programs.
Published data in a prominent health publication shows that while obese individuals frequently drop substantial amounts of their body weight while undergoing treatment, the mass is regained at an estimated rate of nearly a kilo each month after stopping.
"Individuals buying these medications must be aware of the risk of quick weight regain when the treatment is stopped," cautioned expert Dr. Susan Jebb.
This pace of regain suggests a return to starting mass within about a year and a half.
Comparing Treatments
The study, which examined 37 of trials involving thousands of patients, compared the outcomes of the injectable medications with other pills.
The team note that people who lose weight through lifestyle changes alone usually see a less rapid creep back—approximately 100 grams monthly—after stopping.
The Reason for the Fast Rebound
Experts propose the way of the injections accounts for the heightened rebound.
These medications copy a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Long-term administration of GLP-1 levels far above than normal might result in the system to produce less of its endogenous hormone, and could lessen responsiveness to its actions," noted Dr. Adam Collins, a dietetics expert.
"Stopping of this GLP-1 'fix' means hunger is unsuppressed, making binge eating much more probable."
A Lifelong Condition?
The NHS advise the injections for people with obesity-related health risks, alongside prescribed lifestyle changes.
Professionals contend that, due to the significant potential of weight regain, the therapy might need to be ongoing.
This opinion is echoed by pharmaceutical companies, who say that the results "underscore the chronic character of excess weight," akin to managing conditions like hypertension.
User Testimonies
People who have discontinued the jabs explain a sudden resurgence of hunger.
"It was like a trigger activating and I was suddenly ravenous," recalled a patient.
The struggle is compounded if patients have not established lasting lifestyle or habit modifications during therapy.
Significant Use
Survey data show that millions of adults in the UK have used these injections in the past year, with desire continuing to grow.
- Adoption is more common among women than males.
- The 40s and 50s age group shows the greatest usage rates.
- Many obtain the drugs through private prescriptions rather than the NHS.
Finally, researchers stress that while the jabs are potent agents for shedding pounds, they are not a magic fix and long-term success hinges on integrated behavioural changes.
