Fresh analysis suggests that patients who stop using popular GLP-1 drugs like semaglutide or tirzepatide can put back on shed pounds far faster than those who halt traditional lifestyle plans.
Published data in a prominent health publication demonstrates that while obese individuals frequently drop substantial amounts of their body weight while using the jabs, the mass comes back at an average rate of 0.8 kg per month after stopping.
"Users buying such drugs should be cognizant of the potential of quick rebound weight gain when the medication is stopped," warns expert Dr. Susan Jebb.
That rate of recovery means a return to original mass within about one and a half years.
Weighing Treatments
The research, which looked at 37 of trials involving thousands of patients, contrasted the effects of the injectable medications with conventional dieting.
Researchers note that people who shed pounds through lifestyle changes alone generally see a more gradual weight regain—around 0.1 kg a month—post-intervention.
The Reason for the Quick Regain
Experts propose the way of the injections accounts for the amplified regain.
GLP-1 drugs imitate a body's own chemical called GLP-1, which moderates appetite.
"Long-term administration of the hormone levels several times higher than normal could lead to the body to generate a reduced amount of its own natural hormone, and could diminish sensitivity to its effects," noted Dr. Adam Collins, a dietetics expert.
"Stopping of this medication results in hunger is no longer kept in check, making excessive eating much more probable."
An Ongoing Disease?
Medical guidelines advise the jabs for individuals with weight-linked health risks, accompanied by recommended diet and exercise modifications.
Many experts argue that, given the significant potential of relapse, the treatment might need to be long-term.
This perspective is supported by pharmaceutical companies, who state that the results "underscore the long-term character of excess weight," comparing it to managing conditions like hypertension.
User Experiences
Users who have come off the medication report a sudden resurgence of cravings.
"It felt as if something that goes on and you become extremely hungry," described one woman.
The struggle is compounded if users have not developed permanent lifestyle or habit modifications during therapy.
Widespread Adoption
Figures suggest that millions of adults in the UK have tried these injections in the last 12 months, with demand being substantial.
- Adoption is higher among women compared to males.
- The 40s and 50s demographic shows the greatest level of interest.
- Many access the medications through private healthcare rather than the NHS.
Finally, clinicians caution that while the jabs are potent agents for shedding pounds, they are not a standalone fix and maintained weight loss relies on integrated behavioural changes.
