A recent study indicates that people who discontinue popular weight-loss injections like Mounjaro or Wegovy may regain lost weight far faster than those who halt conventional diet and exercise programs.
Research printed in a major medical journal demonstrates that while obese people can lose a large proportion of their total mass while undergoing treatment, the weight comes back at an average rate of nearly a kilo each month after stopping.
"Users buying these treatments should be cognizant of the risk of quick weight regain when the medication ends," stated lead investigator Dr. Susan Jebb.
Such speed of recovery suggests a return to starting mass in about 18 months.
Comparing Therapies
The study, which reviewed 37 of trials involving over 9,000 of participants, compared the results of the injectable medications with conventional dieting.
Scientists emphasize that people who shed pounds through lifestyle changes alone usually see a less rapid creep back—perhaps 100 grams monthly—after stopping.
Explaining the Rapid Regain
Experts suggest the way of the injections accounts for the accelerated weight return.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which moderates appetite.
"Sustained high doses of the hormone levels several times higher than normal could lead to the body to produce less of its own natural hormone, and could lessen sensitivity to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this GLP-1 'fix' results in appetite is no longer kept in check, making overeating much more probable."
A Lifelong Disease?
Medical guidelines suggest the injections for individuals with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Many experts say that, considering the likelihood of weight regain, the therapy is often long-term.
This view is reinforced by pharmaceutical companies, who note that the findings "emphasize the long-term character of excess weight," similar to managing conditions like high blood pressure.
User Accounts
People who have discontinued the medication explain a powerful resurgence of hunger.
"It felt as if a switch flipping and you become starving," said one woman.
The struggle is exacerbated if patients have not established lasting lifestyle or habit modifications during therapy.
Growing Use
Recent estimates show that millions of adults in the UK have tried these injections in the past year, with demand continuing to grow.
- Use is higher among women than men.
- The middle-aged age group shows the highest level of interest.
- Many access the drugs through private prescriptions rather than public health services.
In conclusion, clinicians stress that while GLP-1 drugs are powerful agents for shedding pounds, they are not a standalone cure and lasting health benefits likely depends on integrated lifestyle support.
