New research indicates that patients who stop using new weight-loss injections like Mounjaro or Wegovy can put back on lost weight far faster than those who stop traditional lifestyle programs.
Published data in a prominent health publication shows that while obese individuals can lose substantial amounts of their body weight while using the jabs, the weight comes back at an average rate of 0.8 kg per month after stopping.
"Individuals purchasing such treatments must be informed of the risk of fast rebound weight gain when the treatment concludes," cautioned researcher Dr. Susan Jebb.
This pace of regain implies a reversion to pre-treatment weight in about one and a half years.
Analyzing Treatments
The research, which looked at 37 of trials involving thousands of participants, contrasted the effects of GLP-1 agonists with conventional dieting.
Researchers point out that individuals who shed pounds through lifestyle changes alone typically see a slower creep back—perhaps 0.1 kg a month—once they finish.
Explaining the Fast Rebound
Experts suggest the mode of action of the injections is key to understanding the amplified rebound.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which controls appetite.
"Artificially providing the hormone levels far above than normal may cause the body to generate a reduced amount of its own natural hormone, and may also diminish responsiveness to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this hormone supplement means hunger is uncontrolled, making binge eating far more likely."
A Chronic Issue?
Health authorities recommend the jabs for people with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians say that, considering the likelihood of weight regain, the therapy might need to be long-term.
This opinion is reinforced by drug manufacturers, who state that the results "emphasize the long-term nature of obesity," similar to managing conditions like diabetes.
User Accounts
Users who have stopped the jabs explain a intense return of cravings.
"It was like something that goes on and you become extremely hungry," recalled an individual.
This difficulty is compounded if individuals have not established lasting lifestyle or habit changes during therapy.
Growing Adoption
Recent estimates suggest that millions of people in the UK have tried these injections in the past year, with desire continuing to grow.
- Use is more common among females compared to males.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
Ultimately, clinicians caution that while the jabs are potent tools for weight loss, they are not a permanent solution and long-term success hinges on combined lifestyle management.
