New research indicates that people 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.
Published data in a leading health publication shows that while obese individuals can lose a large proportion of their total mass while using the jabs, the mass is regained at an estimated rate of 0.8 kg per month after stopping.
"Individuals using these medications should be cognizant of the potential of fast weight regain when the treatment ends," cautioned researcher Dr. Susan Jebb.
This pace of recovery means a return to starting mass in about a year and a half.
Analyzing Treatments
The research, which examined dozens of trials involving over 9,000 of patients, contrasted the results of the injectable medications with older methods.
Scientists point out that people who shed pounds through lifestyle changes alone usually experience a less rapid weight regain—perhaps 100 grams monthly—post-intervention.
Explaining the Rapid Regain
Experts believe the mode of action of the jabs explains the accelerated rebound.
These medications copy a natural hormone called glucagon-like peptide-1, which moderates appetite.
"Sustained high doses of the hormone concentrations several times higher than normal might result in the body to generate a reduced amount of its own natural hormone, and could diminish responsiveness to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this medication results in appetite is unsuppressed, making overeating much more probable."
A Lifelong Condition?
The NHS recommend the jabs for individuals with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
Many experts argue that, given the likelihood of relapse, the treatment is often long-term.
This view is supported by pharmaceutical companies, who state that the results "emphasize the persistent nature of excess weight," comparing it to managing diseases like diabetes.
User Testimonies
People who have stopped the jabs describe a powerful return of cravings.
"It felt as if something flipping and you're instantly ravenous," described a patient.
This difficulty is exacerbated if individuals have not established sustainable dietary or behavioural modifications during therapy.
Growing Adoption
Survey data suggest that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with demand being substantial.
- Use is higher among women than men.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the medications through private prescriptions rather than the NHS.
Finally, researchers stress that while these medications are potent agents for weight loss, they are not a magic cure and long-term success relies on combined lifestyle management.
