Fresh analysis suggests that individuals who discontinue popular weight-loss injections like Wegovy and Mounjaro may regain lost weight much more quickly than those who end conventional lifestyle programs.
Published data in a prominent health publication shows that while obese people frequently drop a large proportion of their total mass while using the jabs, the weight comes back at an estimated rate of 0.8 kg per month after stopping.
"Users using these medications need to be informed of the danger of fast rebound weight gain when the medication concludes," stated researcher Dr. Susan Jebb.
Such speed of recovery implies a return to starting weight within about a year and a half.
Comparing Approaches
The analysis, which looked at 37 of trials involving thousands of patients, contrasted the results of the injectable medications with conventional dieting.
Scientists note that people who shed pounds through diet and exercise typically see a slower weight regain—perhaps 100 grams monthly—once they finish.
The Reason for the Quick Regain
Doctors believe the mechanism of the drugs accounts for the amplified rebound.
GLP-1 drugs mimic a natural hormone called GLP-1, which moderates feelings of fullness.
"Artificially providing GLP-1 concentrations far above than normal may cause the body to produce less of its endogenous hormone, and could reduce sensitivity to its effects," said Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this hormone supplement means hunger is uncontrolled, making overeating much more probable."
An Ongoing Issue?
The NHS advise the injections for individuals with obesity-related medical conditions, alongside recommended lifestyle changes.
A number of clinicians argue that, due to the high risk of weight regain, the therapy is often ongoing.
This perspective is reinforced by drug manufacturers, who note that the results "highlight the persistent nature of excess weight," similar to managing diseases like high blood pressure.
User Accounts
Users who have stopped the medication report a intense return of cravings.
"It was like a trigger flipping and you're instantly extremely hungry," said a patient.
The struggle is exacerbated if individuals have not established lasting dietary or behavioural modifications during treatment.
Widespread Use
Survey data suggest that a significant number of people in the UK have tried these injections in the past year, with desire continuing to grow.
- Use is higher among females compared to males.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion access the drugs through private prescriptions rather than the NHS.
Ultimately, clinicians emphasize that while GLP-1 drugs are powerful agents for weight loss, they are not a magic solution and lasting health benefits likely depends on ongoing lifestyle support.
