New research indicates that individuals who come off popular weight-loss injections like Mounjaro or Wegovy tend to recover reduced body mass at a significantly accelerated pace than those who halt conventional lifestyle programs.
Research printed in a leading health publication points out that while obese individuals frequently drop substantial amounts of their body weight while undergoing treatment, the weight comes back at an estimated rate of 0.8 kg per month once they quit.
"Individuals buying such drugs need to be cognizant of the danger of quick rebound weight gain when the treatment concludes," cautioned expert Dr. Susan Jebb.
That rate of regain means a reversion to original weight within about a year and a half.
Comparing Therapies
The research, which looked at 37 of studies involving thousands of participants, contrasted the effects of the injectable medications with conventional dieting.
The team point out that people who shed pounds through diet and exercise typically have a more gradual creep back—perhaps 0.1 kg a month—once they finish.
Explaining the Quick Rebound
Experts propose the mechanism of the injections is key to understanding the heightened regain.
The injections imitate a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 concentrations far above than normal may cause the body to generate a reduced amount of its endogenous hormone, and may also reduce sensitivity to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this hormone supplement leads to appetite is no longer kept in check, making excessive eating a significant risk."
A Chronic Disease?
Health authorities suggest the injections for individuals with obesity-related medical conditions, alongside recommended diet and exercise modifications.
Professionals contend that, due to the significant potential of relapse, the therapy should be considered ongoing.
This perspective is reinforced by drug manufacturers, who say that the findings "underscore the long-term nature of obesity," similar to managing diseases like diabetes.
User Experiences
Users who have stopped the medication explain a intense resurgence of hunger.
"It felt as if a switch flipping and I was suddenly starving," described an individual.
The struggle is compounded if patients have not developed lasting dietary or behavioural modifications during treatment.
Growing Adoption
Figures indicate that millions of adults in the UK have tried weight-loss jabs in the past year, with demand continuing to grow.
- Adoption is higher among females compared to men.
- The middle-aged demographic shows the greatest usage rates.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
Finally, experts caution that while these medications are powerful agents for shedding pounds, they are not a permanent solution and maintained weight loss relies on ongoing lifestyle management.
