A recent study indicates that individuals who come off blockbuster slimming jabs like semaglutide or tirzepatide may regain shed pounds much more quickly than those who halt traditional lifestyle plans.
Published data in a leading medical journal demonstrates that while obese people often shed about a fifth of their body weight while undergoing treatment, the weight is regained at an estimated rate of nearly a kilo each month once they quit.
"Users buying such treatments must be informed of the potential of rapid rebound weight gain when the medication is stopped," cautioned lead investigator Dr. Susan Jebb.
That rate of regain means a return to pre-treatment mass within about one and a half years.
Comparing Therapies
The research, which examined 37 of trials involving over 9,000 of patients, compared the effects of these new drugs with conventional dieting.
Researchers point out that people who shed pounds through diet and exercise usually experience a more gradual creep back—approximately 0.1 kg a month—post-intervention.
Explaining the Rapid Regain
Nutrition scientists believe the way of the jabs is key to understanding the heightened rebound.
These medications mimic a body's own chemical called GLP-1, which controls appetite.
"Sustained high doses of the hormone concentrations several times higher than normal might result in the system to generate a reduced amount of its own natural hormone, and may also reduce responsiveness to its actions," explained Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this medication results in appetite is uncontrolled, making binge eating a significant risk."
A Lifelong Issue?
The NHS advise the jabs for people with weight-linked medical conditions, alongside prescribed lifestyle changes.
A number of clinicians argue that, due to the likelihood of weight regain, the therapy is often ongoing.
This perspective is supported by pharmaceutical companies, who say that the findings "underscore the chronic nature of obesity," akin to managing diseases like hypertension.
User Testimonies
Individuals who have stopped the jabs report a intense return of appetite.
"It felt as if something flipping and you're instantly ravenous," recalled one woman.
This challenge is compounded if users have not established sustainable dietary or behavioural modifications during therapy.
Growing Adoption
Survey data show that a significant number of people in the UK have used these injections in the past year, with demand remaining high.
- Adoption is greater among females compared to men.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion access the drugs through private prescriptions rather than the NHS.
In conclusion, experts emphasize that while these medications are potent agents for weight loss, they are not a standalone solution and long-term success likely depends on combined behavioural management.
