Fresh analysis reveals that people who discontinue popular slimming jabs like Mounjaro or Wegovy may regain lost weight far faster than those who stop conventional lifestyle regimens.
Published data in a prominent health publication demonstrates that while obese people can lose substantial amounts of their body weight while using the jabs, the mass is regained at an average rate of 0.8 kg per month upon discontinuation.
"People purchasing such treatments must be cognizant of the danger of quick rebound weight gain when the treatment is stopped," cautioned expert Dr. Susan Jebb.
That rate of regain suggests a return to original weight within about 18 months.
Comparing Approaches
The analysis, which examined 37 of studies involving over 9,000 of participants, contrasted the results of these new drugs with other pills.
The team emphasize that individuals who shed pounds through lifestyle changes alone usually see a slower weight regain—around 100 grams monthly—post-intervention.
The Reason for the Quick Regain
Experts suggest the way of the injections accounts for the accelerated regain.
The injections imitate a natural hormone called glucagon-like peptide-1, which controls hunger.
"Sustained high doses of GLP-1 concentrations several times higher than normal might result in the system to produce less of its own natural GLP-1, and could lessen sensitivity to its effects," noted Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this medication means appetite is unsuppressed, making binge eating far more likely."
A Chronic Disease?
The NHS recommend the jabs for people with weight-linked medical conditions, alongside prescribed lifestyle changes.
Professionals contend that, due to the likelihood of weight regain, the treatment should be considered long-term.
This perspective is supported by drug manufacturers, who note that the results "highlight the long-term nature of excess weight," akin to managing diseases like diabetes.
User Experiences
Users who have stopped the jabs explain a sudden return of cravings.
"I experienced a switch activating and you're instantly extremely hungry," recalled an individual.
This difficulty is compounded if users have not adopted permanent lifestyle or habit modifications during therapy.
Growing Interest
Survey data indicate that millions of people in the UK have used these injections in the past year, with demand remaining high.
- Use is greater among females than males.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
Finally, clinicians caution that while GLP-1 drugs are powerful agents for weight loss, they are not a standalone solution and maintained weight loss likely depends on ongoing lifestyle management.
