Fresh analysis suggests that patients who discontinue blockbuster slimming jabs like Mounjaro or Wegovy may regain lost weight at a significantly accelerated pace than those who stop conventional diet and exercise plans.
Published data in a leading medical journal points out that while obese individuals frequently drop substantial amounts of their total mass while using the jabs, the weight comes back at an average rate of nearly a kilo each month after stopping.
"Individuals using these drugs need to be cognizant of the danger of rapid rebound weight gain when the therapy concludes," stated lead investigator Dr. Susan Jebb.
This pace of recovery suggests a reversion to starting mass within about 18 months.
Weighing Approaches
The study, which looked at 37 of trials involving thousands of patients, compared the effects of the injectable medications with other pills.
The team point out that people who shed pounds through diet and exercise usually see a less rapid creep back—around 100 grams monthly—once they finish.
The Reason for the Fast Regain
Nutrition scientists believe the mode of action of the jabs accounts for the accelerated regain.
The injections mimic a natural hormone called glucagon-like peptide-1, which helps regulate hunger.
"Artificially providing the hormone levels far above than the body's typical production may cause the body to produce less of its endogenous GLP-1, and may also diminish responsiveness to its actions," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement leads to appetite is uncontrolled, making excessive eating a significant risk."
A Chronic Condition?
The NHS suggest the jabs for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Many experts say that, considering the significant potential of weight regain, the treatment is often long-term.
This perspective is supported by pharmaceutical companies, who note that the findings "emphasize the chronic character of obesity," similar to managing diseases like high blood pressure.
Patient Testimonies
Users who have stopped the jabs describe a intense return of cravings.
"It felt as if something activating and you become ravenous," described an individual.
The struggle is worsened if individuals have not adopted lasting lifestyle or habit modifications during therapy.
Widespread Interest
Recent estimates show that a significant number of people in the UK have tried these injections in the last 12 months, with interest continuing to grow.
- Adoption is greater among women than males.
- The 40s and 50s age group shows the highest usage rates.
- Many access the medications through private healthcare rather than the NHS.
In conclusion, clinicians caution that while the jabs are effective tools for shedding pounds, they are not a magic fix and lasting health benefits likely depends on integrated behavioural management.
