Fresh analysis indicates that individuals who discontinue popular slimming jabs like Wegovy and Mounjaro may regain shed pounds far faster than those who stop traditional lifestyle programs.
Findings released in a major medical journal demonstrates that while overweight individuals frequently drop about a fifth of their body weight while using the jabs, the weight returns at an average rate of nearly a kilo each month after stopping.
"Individuals purchasing these treatments need to be cognizant of the danger of fast weight regain when the medication concludes," warns lead investigator Dr. Susan Jebb.
That rate of recovery implies a return to starting mass within about a year and a half.
Weighing Therapies
The analysis, which reviewed 37 of studies involving thousands of patients, compared the outcomes of these new drugs with other pills.
Scientists emphasize that individuals who shed pounds through dieting typically experience a slower weight regain—around 100 grams monthly—once they finish.
The Reason for the Fast Rebound
Doctors suggest the mechanism of the drugs accounts for the accelerated weight return.
The injections mimic a natural hormone called GLP-1, which moderates appetite.
"Sustained high doses of GLP-1 concentrations several times higher than the body's typical production may cause the system to generate a reduced amount of its own natural hormone, and may also reduce sensitivity to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Stopping of this medication leads to hunger is no longer kept in check, making excessive eating far more likely."
A Chronic Condition?
The NHS advise the jabs for people with weight-linked medical conditions, alongside prescribed lifestyle changes.
Professionals argue that, considering the significant potential of relapse, the therapy should be considered life-long.
This perspective is echoed by pharmaceutical companies, who note that the findings "underscore the chronic nature of excess weight," similar to managing diseases like hypertension.
Patient Experiences
Users who have discontinued the medication describe a intense resurgence of cravings.
"I experienced something activating and you become starving," recalled a patient.
This challenge is worsened if users have not adopted lasting lifestyle or habit changes during therapy.
Widespread Interest
Figures show that millions of adults in the UK have tried these injections in the past year, with interest being substantial.
- Use is more common among women compared to men.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion access the drugs through private prescriptions rather than the NHS.
In conclusion, researchers caution that while these medications are potent tools for weight loss, they are not a magic cure and long-term success hinges on ongoing lifestyle support.
