New research reveals that patients who stop using blockbuster slimming jabs like semaglutide or tirzepatide tend to recover reduced body mass at a significantly accelerated pace than those who end traditional diet and exercise programs.
Published data in a major health publication demonstrates that while obese individuals can lose substantial amounts of their body weight while using the jabs, the weight returns at an estimated rate of nearly a kilo each month once they quit.
"Users purchasing these medications must be aware of the danger of quick rebound weight gain when the treatment concludes," warns lead investigator Dr. Susan Jebb.
This pace of regain suggests a reversion to pre-treatment mass in about one and a half years.
Analyzing Treatments
The research, which reviewed 37 of trials involving over 9,000 of participants, contrasted the effects of GLP-1 agonists with conventional dieting.
The team point out that individuals who lose weight through diet and exercise generally have a less rapid creep back—around 100 grams monthly—post-intervention.
Understanding the Rapid Regain
Doctors believe the mode of action of the jabs explains the heightened weight return.
The injections copy a body's own chemical called GLP-1, which controls hunger.
"Sustained high doses of GLP-1 concentrations several times higher than normal might result in the body to produce less of its endogenous GLP-1, and could reduce sensitivity to its effects," explained Dr. Adam Collins, a nutrition expert.
"Stopping of this GLP-1 'fix' means hunger is unsuppressed, making excessive eating much more probable."
A Chronic Issue?
The NHS suggest the jabs for people with weight-linked health risks, alongside prescribed lifestyle changes.
A number of clinicians argue that, given the significant potential of weight regain, the therapy is often ongoing.
This perspective is supported by pharmaceutical companies, who state that the findings "highlight the persistent nature of excess weight," comparing it to managing diseases like diabetes.
User Accounts
Users who have come off the medication report a powerful return of appetite.
"It felt as if a trigger activating and you become ravenous," said a patient.
This difficulty is exacerbated if individuals have not established permanent dietary or behavioural modifications during treatment.
Growing Use
Recent estimates indicate that millions of adults in the UK have used weight-loss jabs in the last 12 months, with interest remaining high.
- Adoption is greater among women compared to males.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion access the medications through private prescriptions rather than the NHS.
Finally, experts emphasize that while the jabs are potent agents for weight loss, they are not a standalone fix and lasting health benefits relies on ongoing behavioural support.
