New research indicates that patients who discontinue new weight-loss injections like Wegovy and Mounjaro can put back on lost weight much more quickly than those who halt conventional lifestyle plans.
Research printed in a prominent medical journal points out that while overweight individuals often shed substantial amounts of their body weight while on the medication, the mass returns at an average rate of 0.8 kg per month once they quit.
"People using such drugs need to be cognizant of the danger of fast rebound weight gain when the therapy concludes," cautioned lead investigator Dr. Susan Jebb.
This pace of regain implies a return to pre-treatment mass in about 18 months.
Comparing Treatments
The research, which looked at dozens of studies involving over 9,000 of patients, compared the effects of the injectable medications with conventional dieting.
The team point out that individuals who shed pounds through dieting typically see a more gradual weight regain—approximately 0.1 kg a month—post-intervention.
Understanding the Fast Regain
Doctors propose the mechanism of the injections explains the accelerated rebound.
These medications imitate a body's own chemical called GLP-1, which moderates hunger.
"Sustained high doses of the hormone levels several times higher than the body's typical production could lead to the system to produce less of its endogenous GLP-1, and could diminish sensitivity to its actions," noted Dr. Adam Collins, a nutrition expert.
"Stopping of this hormone supplement means hunger is no longer kept in check, making binge eating far more likely."
A Chronic Issue?
Medical guidelines suggest the injections for people with obesity-related health risks, alongside prescribed lifestyle changes.
Professionals argue that, due to the likelihood of relapse, the treatment should be considered long-term.
This view is supported by drug manufacturers, who say that the findings "highlight the chronic nature of obesity," similar to managing conditions like diabetes.
User Testimonies
Individuals who have come off the medication report a intense resurgence of cravings.
"It was like a trigger that goes on and you're instantly ravenous," said an individual.
The struggle is exacerbated if users have not established permanent lifestyle or habit modifications during therapy.
Significant Use
Figures indicate that a significant number of people in the UK have tried these injections in the past year, with desire remaining high.
- Adoption is more common among females than men.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
In conclusion, experts stress that while these medications are potent agents for shedding pounds, they are not a permanent solution and maintained weight loss likely depends on ongoing lifestyle management.
