Fresh analysis reveals that people who come off popular slimming jabs like semaglutide or tirzepatide tend to recover reduced body mass at a significantly accelerated pace than those who end traditional lifestyle plans.
Findings released in a leading health publication shows that while overweight individuals often shed about a fifth of their total mass while undergoing treatment, the mass comes back at an average rate of 0.8 kg per month upon discontinuation.
"Individuals purchasing such drugs must be aware of the potential of rapid weight regain when the therapy concludes," warns expert Dr. Susan Jebb.
This pace of regain means a reversion to starting mass in about 18 months.
Analyzing Treatments
The study, which reviewed 37 of trials involving over 9,000 of participants, contrasted the outcomes of the injectable medications with conventional dieting.
Scientists note that people who shed pounds through diet and exercise generally have a more gradual weight regain—perhaps 100 grams monthly—after stopping.
Understanding the Fast Regain
Doctors believe the mode of action of the injections accounts for the amplified weight return.
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 system to generate a reduced amount of its own natural GLP-1, and may also lessen responsiveness to its effects," noted Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this medication results in appetite is uncontrolled, making binge eating a significant risk."
A Lifelong Issue?
The NHS recommend the injections for people with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
A number of clinicians contend that, considering the high risk of weight regain, the therapy might need to be life-long.
This view is reinforced by pharmaceutical companies, who note that the results "emphasize the persistent character of excess weight," similar to managing diseases like high blood pressure.
User Testimonies
People who have discontinued the medication report a intense return of hunger.
"It felt as if a switch flipping and you're instantly extremely hungry," said a patient.
This challenge is worsened if patients have not established sustainable lifestyle or habit changes during therapy.
Widespread Use
Figures show that millions of adults in the UK have used weight-loss jabs in the past year, with demand continuing to grow.
- Adoption is greater among women than males.
- The middle-aged demographic shows the highest usage rates.
- A large proportion obtain the medications through private healthcare rather than public health services.
Finally, clinicians emphasize that while these medications are effective agents for weight loss, they are not a magic fix and maintained weight loss likely depends on ongoing lifestyle changes.
