Fresh analysis suggests that patients who stop using new slimming jabs like Mounjaro or Wegovy tend to recover reduced body mass far faster than those who stop conventional diet and exercise programs.
Findings released in a prominent health publication shows that while obese people frequently drop substantial amounts of their body weight while on the medication, the weight comes back at an estimated rate of nearly a kilo each month once they quit.
"People buying these medications must be aware of the potential of quick weight regain when the medication concludes," warns researcher Dr. Susan Jebb.
Such speed of regain implies a reversion to pre-treatment mass within about one and a half years.
Weighing Therapies
The research, which reviewed dozens of studies involving over 9,000 of participants, contrasted the outcomes of GLP-1 agonists with older methods.
Researchers note that individuals who shed pounds through diet and exercise generally experience a more gradual creep back—around 100 grams monthly—post-intervention.
Understanding the Fast Regain
Doctors suggest the mode of action of the injections is key to understanding the heightened weight return.
The injections copy a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of the hormone levels far above than the body's typical production could lead to the system to generate a reduced amount of its endogenous hormone, and could lessen sensitivity to its effects," said Dr. Adam Collins, a nutrition specialist.
"Stopping of this hormone supplement means appetite is no longer kept in check, making overeating far more likely."
A Lifelong Condition?
The NHS suggest the injections for individuals with weight-linked health risks, alongside prescribed diet and exercise modifications.
Professionals say that, considering the high risk of weight regain, the treatment is often long-term.
This perspective is echoed by pharmaceutical companies, who note that the findings "emphasize the persistent nature of excess weight," similar to managing conditions like diabetes.
Patient Experiences
People who have come off the jabs describe a sudden resurgence of cravings.
"It felt as if something activating and you become ravenous," said an individual.
This difficulty is worsened if users have not adopted sustainable lifestyle or habit changes during treatment.
Widespread Use
Survey data show that a significant number of people in the UK have tried these injections in the past year, with interest remaining high.
- Adoption is higher among women compared to men.
- The 40s and 50s age group shows the highest usage rates.
- Many access the drugs through private prescriptions rather than public health services.
Ultimately, researchers caution that while GLP-1 drugs are effective agents for weight loss, they are not a permanent solution and lasting health benefits likely depends on integrated lifestyle management.
