New research indicates that people who stop using popular weight-loss injections like Mounjaro or Wegovy may regain lost weight much more quickly than those who stop traditional diet and exercise plans.
Findings released in a leading health publication demonstrates that while obese individuals often shed a large proportion of their body weight while undergoing treatment, the mass returns at an average rate of 0.8 kg per month upon discontinuation.
"Individuals using these treatments should be informed of the potential of quick weight regain when the therapy is stopped," stated expert Dr. Susan Jebb.
That rate of recovery suggests a return to original mass in about 18 months.
Comparing Treatments
The study, which looked at 37 of trials involving thousands of patients, compared the outcomes of these new drugs with conventional dieting.
Researchers note that people who shed pounds through lifestyle changes alone generally see a slower weight regain—perhaps 100 grams monthly—once they finish.
Explaining the Fast Rebound
Nutrition scientists suggest the way of the injections explains the accelerated regain.
These medications imitate a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of GLP-1 levels several times higher than normal might result in the system to produce less of its endogenous GLP-1, and could reduce responsiveness to its actions," said Dr. Adam Collins, a nutrition expert.
"Stopping of this hormone supplement means hunger is no longer kept in check, making binge eating far more likely."
An Ongoing Condition?
Medical guidelines suggest the injections for people with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Many experts argue that, due to the high risk of relapse, the treatment is often ongoing.
This perspective is reinforced by pharmaceutical companies, who say that the results "underscore the persistent character of obesity," similar to managing diseases like diabetes.
User Testimonies
People who have stopped the medication describe a sudden return of cravings.
"It felt as if a trigger activating and I was suddenly extremely hungry," described a patient.
This difficulty is exacerbated if patients have not developed lasting lifestyle or habit modifications during therapy.
Growing Adoption
Recent estimates show that millions of people in the UK have tried these injections in the last 12 months, with demand remaining high.
- Adoption is higher among females than males.
- The middle-aged demographic shows the highest usage rates.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
Ultimately, researchers stress that while GLP-1 drugs are effective tools for shedding pounds, they are not a permanent solution and maintained weight loss hinges on combined lifestyle management.
