A recent study indicates that people who come off new slimming jabs like semaglutide or tirzepatide tend to recover lost weight at a significantly accelerated pace than those who end traditional diet and exercise programs.
Findings released in a major health publication shows that while overweight individuals often shed substantial amounts of their total mass while using the jabs, the mass returns at an average rate of nearly a kilo each month after stopping.
"Users purchasing these treatments need to be informed of the danger of fast rebound weight gain when the treatment concludes," warns lead investigator Dr. Susan Jebb.
This pace of recovery suggests a reversion to original mass within about 18 months.
Comparing Therapies
The analysis, which looked at dozens of trials involving thousands of participants, compared the results of GLP-1 agonists with older methods.
Scientists point out that people who lose weight through dieting generally experience a less rapid weight regain—perhaps 100 grams monthly—after stopping.
Explaining the Quick Rebound
Nutrition scientists believe the way of the drugs is key to understanding the accelerated rebound.
GLP-1 drugs mimic a natural hormone called GLP-1, which moderates feelings of fullness.
"Sustained high doses of GLP-1 levels several times higher than the body's typical production may cause the system to generate a reduced amount of its endogenous hormone, and could lessen responsiveness to its effects," explained Dr. Adam Collins, a nutrition expert.
"Stopping of this GLP-1 'fix' results in hunger is unsuppressed, making binge eating far more likely."
A Lifelong Issue?
The NHS recommend the injections for people with weight-linked medical conditions, alongside recommended lifestyle changes.
A number of clinicians say that, given the significant potential of weight regain, the treatment should be considered ongoing.
This perspective is supported by pharmaceutical companies, who say that the results "underscore the long-term character of obesity," comparing it to managing conditions like hypertension.
User Experiences
People who have stopped the medication describe a sudden return of cravings.
"I experienced something that goes on and you're instantly ravenous," described one woman.
The struggle is exacerbated if users have not established permanent lifestyle or habit modifications during therapy.
Growing Adoption
Figures suggest that millions of people in the UK have tried weight-loss jabs in the past year, with demand continuing to grow.
- Use is more common among women compared to men.
- The middle-aged demographic shows the greatest usage rates.
- A large proportion access the drugs through private healthcare rather than the NHS.
Finally, experts caution that while the jabs are powerful tools for shedding pounds, they are not a standalone cure and lasting health benefits hinges on combined lifestyle changes.
