New research suggests that patients who discontinue blockbuster weight-loss injections like Wegovy and Mounjaro may regain lost weight far faster than those who stop conventional lifestyle regimens.
Research printed in a major health publication demonstrates that while obese individuals often shed substantial amounts of their total mass while using the jabs, the mass is regained at an estimated rate of nearly a kilo each month after stopping.
"Users purchasing these drugs need to be aware of the risk of rapid weight regain when the treatment concludes," warns researcher Dr. Susan Jebb.
Such speed of recovery suggests a return to original mass within about a year and a half.
Comparing Therapies
The analysis, which looked at dozens of studies involving over 9,000 of patients, contrasted the effects of these new drugs with conventional dieting.
Scientists note that people who shed pounds through diet and exercise generally have a less rapid creep back—perhaps 0.1 kg a month—once they finish.
Explaining the Rapid Rebound
Nutrition scientists believe the mode of action of the injections explains the accelerated regain.
These medications mimic a natural hormone called GLP-1, which controls hunger.
"Artificially providing the hormone levels several times higher than normal may cause the system to produce less of its endogenous GLP-1, and may also diminish responsiveness to its actions," noted Dr. Adam Collins, a nutrition researcher.
"Stopping of this medication leads to appetite is uncontrolled, making binge eating much more probable."
An Ongoing Disease?
Medical guidelines suggest the jabs for people with weight-linked health risks, accompanied by recommended lifestyle changes.
Professionals argue that, given the significant potential of relapse, the therapy might need to be ongoing.
This perspective is supported by pharmaceutical companies, who state that the findings "emphasize the chronic nature of excess weight," comparing it to managing diseases like high blood pressure.
User Testimonies
People who have come off the medication explain a powerful return of hunger.
"It felt as if a switch that goes on and you're instantly starving," described a patient.
This difficulty is exacerbated if users have not adopted lasting lifestyle or habit modifications during treatment.
Significant Use
Survey data indicate that a significant number of people in the UK have used weight-loss jabs in the past year, with demand being substantial.
- Use is higher among females than males.
- The 40s and 50s demographic shows the highest usage rates.
- Many obtain the drugs through private prescriptions rather than the NHS.
Ultimately, experts emphasize that while GLP-1 drugs are effective agents for shedding pounds, they are not a standalone fix and lasting health benefits hinges on integrated behavioural support.
