New research indicates that patients who come off blockbuster weight-loss injections like semaglutide or tirzepatide may regain shed pounds at a significantly accelerated pace than those who end traditional lifestyle plans.
Findings released in a prominent health publication points out that while overweight individuals often shed substantial amounts of their total mass while undergoing treatment, the mass returns at an estimated rate of 0.8 kg per month after stopping.
"Individuals using these medications must be informed of the danger of fast weight regain when the treatment is stopped," stated researcher Dr. Susan Jebb.
Such speed of regain implies a reversion to starting weight in about a year and a half.
Comparing Approaches
The analysis, which examined dozens of trials involving over 9,000 of participants, compared the outcomes of GLP-1 agonists with older methods.
Scientists note that people who shed pounds through diet and exercise usually have a slower creep back—approximately 100 grams monthly—once they finish.
The Reason for the Quick Rebound
Experts believe the way of the injections accounts for the heightened weight return.
The injections copy a natural hormone called GLP-1, which moderates feelings of fullness.
"Artificially providing the hormone levels far above than normal may cause the system to produce less of its endogenous GLP-1, and may also lessen responsiveness to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this medication leads to appetite is no longer kept in check, making excessive eating much more probable."
A Chronic Issue?
The NHS recommend the injections for people with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
Professionals contend that, due to the likelihood of weight regain, the treatment is often long-term.
This perspective is echoed by pharmaceutical companies, who note that the findings "underscore the chronic nature of excess weight," similar to managing conditions like hypertension.
User Testimonies
Users who have come off the jabs explain a powerful return of hunger.
"It was like a trigger flipping and you become extremely hungry," said a patient.
This challenge is compounded if patients have not established sustainable dietary or behavioural changes during therapy.
Widespread Adoption
Recent estimates indicate that millions of adults in the UK have used weight-loss jabs in the last 12 months, with demand continuing to grow.
- Use is greater among females than males.
- The middle-aged demographic shows the highest level of interest.
- Many access the medications through private prescriptions rather than public health services.
Ultimately, clinicians caution that while the jabs are potent agents for weight loss, they are not a magic cure and long-term success relies on ongoing behavioural management.
