Patients Stopping Anti-Obesity Injections Put On Weight Far More Rapidly Than Dieters
Fresh analysis indicates that people who come off new GLP-1 drugs like semaglutide or tirzepatide may regain shed pounds at a significantly accelerated pace than those who halt conventional diet and exercise plans.
Published data in a leading health publication shows that while overweight individuals frequently drop a large proportion of their body weight while using the jabs, the mass is regained at an estimated rate of 0.8 kg per month after stopping.
"Individuals purchasing such treatments must be cognizant of the danger of fast rebound weight gain when the therapy concludes," cautioned expert Dr. Susan Jebb.
This pace of regain means a return to pre-treatment weight within about one and a half years.
Comparing Approaches
The analysis, which looked at 37 of studies involving thousands of patients, compared the results of these new drugs with conventional dieting.
Scientists note that individuals who shed pounds through diet and exercise usually experience a less rapid creep back—perhaps 0.1 kg a month—post-intervention.
Explaining the Rapid Rebound
Doctors propose the mode of action of the drugs accounts for the heightened regain.
GLP-1 drugs imitate a body's own chemical called GLP-1, which helps regulate appetite.
"Long-term administration of GLP-1 levels 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 reduce sensitivity to its actions," noted Dr. Adam Collins, a dietetics specialist.
"Stopping of this hormone supplement means appetite is no longer kept in check, making excessive eating a significant risk."
A Chronic Condition?
Medical guidelines advise the jabs for people with weight-linked medical conditions, alongside recommended lifestyle changes.
A number of clinicians contend that, considering the significant potential of relapse, the treatment might need to be life-long.
This opinion is reinforced by drug manufacturers, who note that the findings "emphasize the persistent character of excess weight," similar to managing conditions like high blood pressure.
Patient Accounts
People who have come off the medication describe a sudden resurgence of hunger.
"It was like a switch that goes on and you become extremely hungry," recalled an individual.
This challenge is compounded if individuals have not adopted permanent dietary or behavioural modifications during therapy.
Widespread Adoption
Recent estimates indicate that millions of adults in the UK have tried these injections in the last 12 months, with demand continuing to grow.
- Adoption is more common among females than men.
- The middle-aged demographic shows the greatest usage rates.
- Many obtain the medications through private healthcare rather than the NHS.
In conclusion, experts stress that while the jabs are powerful agents for shedding pounds, they are not a standalone fix and lasting health benefits hinges on integrated behavioural changes.
