A recent study reveals that patients who come off blockbuster slimming jabs like semaglutide or tirzepatide can put back on lost weight much more quickly than those who end traditional lifestyle regimens.
Findings released in a major health publication shows that while obese individuals frequently drop a large proportion of their total mass while using the jabs, the weight comes back at an estimated rate of 0.8 kg per month once they quit.
"Individuals using such treatments need to be informed of the potential of rapid weight regain when the medication is stopped," warns expert Dr. Susan Jebb.
That rate of recovery means a return to original mass in about one and a half years.
Analyzing Treatments
The study, which examined dozens of studies involving thousands of participants, compared the effects of GLP-1 agonists with conventional dieting.
Scientists emphasize that individuals who shed pounds through lifestyle changes alone usually experience a more gradual weight regain—perhaps 100 grams monthly—post-intervention.
Explaining the Quick Rebound
Doctors suggest the mode of action of the drugs explains the heightened regain.
GLP-1 drugs copy a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of the hormone concentrations several times higher than normal may cause the system to produce less of its endogenous hormone, and could diminish sensitivity to its actions," explained Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this hormone supplement leads to appetite is no longer kept in check, making overeating a significant risk."
An Ongoing Disease?
Medical guidelines advise the injections for people with obesity-related medical conditions, alongside recommended diet and exercise modifications.
Professionals contend that, due to the high risk of relapse, the therapy might need to be ongoing.
This opinion is echoed by pharmaceutical companies, who note that the results "highlight the chronic character of excess weight," comparing it to managing conditions like diabetes.
Patient Accounts
Individuals who have come off the medication report a intense return of appetite.
"I experienced a switch activating and you become extremely hungry," described one woman.
This difficulty is worsened if users have not developed permanent dietary or behavioural changes during treatment.
Significant Adoption
Recent estimates show that a significant number of people in the UK have tried weight-loss jabs in the past year, with desire being substantial.
- Use is more common among females compared to men.
- The 40s and 50s age group shows the highest level of interest.
- A large proportion access the medications through private prescriptions rather than public health services.
Ultimately, experts caution that while GLP-1 drugs are powerful tools for shedding pounds, they are not a permanent fix and long-term success hinges on combined lifestyle management.
