A recent study indicates that patients who discontinue popular slimming jabs like semaglutide or tirzepatide can put back on reduced body mass far faster than those who stop conventional lifestyle plans.
Research printed in a prominent medical journal shows that while overweight individuals frequently drop a large proportion of their body weight while on the medication, the weight is regained at an average rate of nearly a kilo each month once they quit.
"Users buying such medications should be cognizant of the potential of fast weight regain when the treatment concludes," stated expert Dr. Susan Jebb.
That rate of recovery means a return to pre-treatment weight within about one and a half years.
Comparing Treatments
The research, which looked at dozens of trials involving over 9,000 of participants, compared the results 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 creep back—approximately 0.1 kg a month—after stopping.
Explaining the Quick Rebound
Experts believe the way of the jabs accounts for the heightened regain.
These medications copy a natural hormone called glucagon-like peptide-1, which moderates appetite.
"Long-term administration of the hormone levels several times higher than normal could lead to the system to produce less of its endogenous GLP-1, and could lessen sensitivity to its actions," noted Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this GLP-1 'fix' leads to hunger is uncontrolled, making excessive eating much more probable."
A Lifelong Issue?
Health authorities advise the injections for individuals with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals argue that, given the high risk of weight regain, the therapy might need to be long-term.
This opinion is reinforced by pharmaceutical companies, who say that the findings "underscore the persistent character of excess weight," comparing it to managing diseases like diabetes.
User Testimonies
People who have stopped the medication explain a powerful resurgence of cravings.
"I experienced a trigger flipping and you're instantly ravenous," recalled an individual.
The struggle is compounded if users have not adopted lasting dietary or behavioural modifications during treatment.
Widespread Interest
Survey data show that millions of people in the UK have used these injections in the past year, with interest being substantial.
- Adoption is higher among females compared to men.
- The middle-aged age group shows the highest level of interest.
- Many access the medications through private healthcare rather than public health services.
Ultimately, experts stress that while the jabs are potent agents for shedding pounds, they are not a permanent fix and long-term success hinges on combined behavioural support.
