A recent study reveals that patients who come off new weight-loss injections like semaglutide or tirzepatide can put back on lost weight far faster than those who stop conventional lifestyle programs.
Findings released in a leading medical journal demonstrates that while obese people often shed substantial amounts of their body weight while using the jabs, the mass returns at an average rate of nearly a kilo each month once they quit.
"People buying such treatments should be aware of the danger of rapid weight regain when the medication concludes," stated lead investigator Dr. Susan Jebb.
This pace of regain implies a return to pre-treatment mass within about one and a half years.
Weighing Treatments
The research, which reviewed dozens of studies involving thousands of patients, contrasted the outcomes of GLP-1 agonists with conventional dieting.
The team point out that people who lose weight through lifestyle changes alone typically experience a more gradual weight regain—approximately 0.1 kg a month—after stopping.
Explaining the Rapid Rebound
Experts propose the mechanism of the injections is key to understanding the heightened rebound.
GLP-1 drugs mimic a natural hormone called GLP-1, which moderates hunger.
"Sustained high doses of GLP-1 concentrations far above than normal may cause the body to generate a reduced amount of its endogenous GLP-1, and could diminish responsiveness to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this GLP-1 'fix' leads to appetite is unsuppressed, making overeating far more likely."
A Chronic Condition?
Health authorities suggest the injections for people with obesity-related health risks, alongside recommended lifestyle changes.
Professionals argue that, considering the significant potential of relapse, the therapy should be considered long-term.
This perspective is echoed by pharmaceutical companies, who note that the findings "highlight the persistent nature of excess weight," similar to managing diseases like high blood pressure.
Patient Accounts
Individuals who have come off the medication describe a sudden resurgence of cravings.
"It was like a switch flipping and you become extremely hungry," said a patient.
This challenge is exacerbated if users have not developed permanent lifestyle or habit modifications during therapy.
Growing Interest
Figures show that a significant number of people in the UK have tried these injections in the past year, with interest remaining high.
- Adoption is more common among females compared to males.
- The middle-aged age group shows the greatest level of interest.
- A large proportion obtain the medications through private healthcare rather than public health services.
Finally, experts caution that while these medications are powerful tools for shedding pounds, they are not a magic fix and maintained weight loss hinges on integrated lifestyle changes.
