A recent study reveals that patients who discontinue popular slimming jabs like semaglutide or tirzepatide tend to recover reduced body mass much more quickly than those who stop conventional diet and exercise programs.
Published data in a major medical journal demonstrates that while overweight people frequently drop substantial amounts of their body weight while undergoing treatment, the weight comes back at an estimated rate of 0.8 kg per month after stopping.
"People purchasing such treatments need to be aware of the risk of fast rebound weight gain when the medication concludes," stated expert Dr. Susan Jebb.
Such speed of regain suggests a return to pre-treatment weight in about 18 months.
Analyzing Approaches
The research, which reviewed dozens of studies involving over 9,000 of participants, contrasted the effects of GLP-1 agonists with other pills.
Scientists note that individuals who lose weight through dieting typically have a less rapid creep back—approximately 100 grams monthly—once they finish.
The Reason for the Fast Regain
Doctors suggest the mechanism of the injections is key to understanding the amplified weight return.
These medications imitate a body's own chemical called GLP-1, which controls hunger.
"Long-term administration of GLP-1 concentrations several times higher than normal may cause the system to produce less of its own natural GLP-1, and could reduce responsiveness to its actions," noted Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this hormone supplement leads to hunger is uncontrolled, making excessive eating a significant risk."
A Lifelong Disease?
The NHS recommend the jabs for people with obesity-related health risks, accompanied by prescribed diet and exercise modifications.
A number of clinicians argue that, due to the significant potential of relapse, the treatment is often long-term.
This perspective is echoed by drug manufacturers, who say that the results "highlight the chronic nature of obesity," akin to managing conditions like diabetes.
User Accounts
Users who have come off the medication explain a powerful return of cravings.
"It was like something that goes on and you're instantly extremely hungry," described one woman.
This challenge is exacerbated if patients have not adopted permanent dietary or behavioural modifications during therapy.
Significant Use
Figures indicate that millions of people in the UK have used these injections in the last 12 months, with demand continuing to grow.
- Adoption is greater among females than males.
- The middle-aged demographic shows the greatest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
Ultimately, researchers caution that while these medications are effective tools for shedding pounds, they are not a permanent solution and lasting health benefits relies on ongoing lifestyle management.
