A recent study reveals that patients who stop using new weight-loss injections like semaglutide or tirzepatide can put back on shed pounds at a significantly accelerated pace than those who end conventional lifestyle plans.
Published data in a major medical journal shows that while obese individuals often shed a large proportion of their body weight while on the medication, the weight is regained at an estimated rate of nearly a kilo each month once they quit.
"Users buying these treatments must be aware of the danger of rapid rebound weight gain when the medication concludes," stated lead investigator Dr. Susan Jebb.
That rate of regain implies a reversion to original weight within about one and a half years.
Analyzing Treatments
The analysis, which looked at dozens of studies involving over 9,000 of participants, compared the outcomes of these new drugs with older methods.
Scientists note that individuals who shed pounds through lifestyle changes alone usually experience a less rapid creep back—around 100 grams monthly—post-intervention.
The Reason for the Rapid Rebound
Experts believe the mechanism of the injections explains the heightened weight return.
GLP-1 drugs imitate a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of the hormone concentrations far above than the body's typical production may cause the body to generate a reduced amount of its endogenous GLP-1, and may also diminish sensitivity to its actions," said Dr. Adam Collins, a dietetics expert.
"Stopping of this medication means appetite is no longer kept in check, making overeating much more probable."
A Chronic Disease?
Health authorities suggest the injections for people with obesity-related health risks, alongside prescribed diet and exercise modifications.
Professionals argue that, considering the likelihood of relapse, the therapy should be considered life-long.
This perspective is reinforced by pharmaceutical companies, who state that the findings "highlight the persistent character of excess weight," similar to managing diseases like hypertension.
User Experiences
Individuals who have come off the jabs explain a intense return of appetite.
"It felt as if a switch that goes on and you're instantly ravenous," said a patient.
This difficulty is compounded if users have not developed lasting dietary or behavioural modifications during therapy.
Widespread Adoption
Figures show that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with demand continuing to grow.
- Use is higher among females than males.
- The 40s and 50s age group shows the highest usage rates.
- Many access the drugs through private healthcare rather than the NHS.
In conclusion, experts stress that while these medications are powerful agents for shedding pounds, they are not a permanent fix and lasting health benefits relies on ongoing behavioural changes.
