A recent study reveals that individuals who discontinue new weight-loss injections like Mounjaro or Wegovy may regain shed pounds far faster than those who end conventional lifestyle plans.
Published data in a leading health publication demonstrates that while obese people can lose substantial amounts of their body weight while using the jabs, the weight returns at an average rate of nearly a kilo each month upon discontinuation.
"Users buying these medications must be cognizant of the risk of fast rebound weight gain when the therapy concludes," warns researcher Dr. Susan Jebb.
That rate of regain suggests a reversion to pre-treatment mass within about a year and a half.
Comparing Treatments
The analysis, which examined 37 of studies involving over 9,000 of participants, contrasted the outcomes of the injectable medications with older methods.
Researchers point out that people who lose weight through lifestyle changes alone typically have a less rapid creep back—perhaps 0.1 kg a month—post-intervention.
Explaining the Fast Regain
Nutrition scientists suggest the mechanism of the injections accounts for the accelerated regain.
The injections mimic a natural hormone called glucagon-like peptide-1, which controls hunger.
"Long-term administration of the hormone levels several times higher than normal could lead to the system to generate a reduced amount of its own natural GLP-1, and could diminish sensitivity to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this hormone supplement results in appetite is no longer kept in check, making excessive eating much more probable."
A Chronic Disease?
The NHS suggest the injections for people with obesity-related health risks, accompanied by prescribed diet and exercise modifications.
Many experts argue that, considering the likelihood of weight regain, the treatment might need to be life-long.
This opinion is reinforced by drug manufacturers, who state that the findings "emphasize the long-term character of obesity," similar to managing conditions like diabetes.
User Accounts
People who have discontinued the jabs report a intense return of cravings.
"It felt as if a trigger flipping and I was suddenly extremely hungry," recalled a patient.
This challenge is exacerbated if users have not developed sustainable lifestyle or habit changes during therapy.
Growing Adoption
Recent estimates suggest that millions of people in the UK have used weight-loss jabs in the past year, with interest continuing to grow.
- Adoption is greater among women than men.
- The middle-aged age group shows the greatest level of interest.
- Many obtain the drugs through private healthcare rather than public health services.
Finally, clinicians stress that while the jabs are potent agents for weight loss, they are not a magic solution and lasting health benefits likely depends on ongoing behavioural management.
