Fresh analysis indicates that individuals who discontinue blockbuster weight-loss injections like Wegovy and Mounjaro tend to recover lost weight at a significantly accelerated pace than those who stop traditional diet and exercise regimens.
Findings released in a prominent medical journal demonstrates that while obese individuals often shed about a fifth of their total mass while using the jabs, the weight returns at an average rate of 0.8 kg per month once they quit.
"Individuals purchasing such treatments need to be informed of the risk of rapid rebound weight gain when the medication is stopped," warns expert Dr. Susan Jebb.
Such speed of regain suggests a return to starting mass in about 18 months.
Weighing Treatments
The research, which reviewed dozens of trials involving thousands of patients, compared the outcomes of these new drugs with older methods.
The team emphasize that individuals who lose weight through diet and exercise typically have a less rapid creep back—around 0.1 kg a month—post-intervention.
The Reason for the Quick Rebound
Doctors propose the mode of action of the injections accounts for the heightened rebound.
The injections mimic a body's own chemical called GLP-1, which helps regulate appetite.
"Sustained high doses of GLP-1 levels far above than normal may cause the body to produce less of its own natural GLP-1, and could reduce responsiveness to its actions," explained Dr. Adam Collins, a dietetics researcher.
"Stopping of this medication means hunger is uncontrolled, making overeating much more probable."
A Chronic Disease?
Health authorities advise the jabs for individuals with weight-linked health risks, accompanied by recommended lifestyle changes.
A number of clinicians contend that, given the likelihood of weight regain, the treatment might need to be long-term.
This perspective is supported by pharmaceutical companies, who note that the results "highlight the long-term character of excess weight," similar to managing diseases like hypertension.
User Testimonies
Individuals who have come off the medication explain a sudden resurgence of appetite.
"It was like a trigger that goes on and you're instantly ravenous," said one woman.
This challenge is worsened if individuals have not developed lasting dietary or behavioural modifications during therapy.
Widespread Interest
Recent estimates show that a significant number of people in the UK have used weight-loss jabs in the past year, with desire remaining high.
- Use is higher among females compared to men.
- The middle-aged age group shows the highest usage rates.
- A large proportion access the medications through private prescriptions rather than the NHS.
In conclusion, researchers emphasize that while GLP-1 drugs are effective tools for shedding pounds, they are not a standalone cure and maintained weight loss likely depends on ongoing behavioural support.
