Fresh analysis indicates that individuals who discontinue new weight-loss injections like Wegovy and Mounjaro tend to recover shed pounds at a significantly accelerated pace than those who end conventional diet and exercise plans.
Research printed in a major medical journal shows that while obese people can lose about a fifth of their body weight while on the medication, the mass returns at an average rate of nearly a kilo each month once they quit.
"Users using such drugs need to be informed of the risk of rapid rebound weight gain when the medication concludes," cautioned expert Dr. Susan Jebb.
This pace of recovery implies a return to original mass within about 18 months.
Analyzing Approaches
The research, which reviewed dozens of studies involving over 9,000 of participants, compared the outcomes of GLP-1 agonists with other pills.
The team point out that people who shed pounds through lifestyle changes alone generally have a less rapid weight regain—around 0.1 kg a month—after stopping.
The Reason for the Fast Regain
Nutrition scientists believe the way of the injections is key to understanding the heightened rebound.
These medications imitate a natural hormone called GLP-1, which moderates appetite.
"Sustained high doses of GLP-1 concentrations several times higher than the body's typical production might result in the body to produce less of its own natural hormone, and could diminish responsiveness to its effects," explained Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this hormone supplement means appetite is unsuppressed, making binge eating far more likely."
An Ongoing Condition?
The NHS advise the jabs for people with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
A number of clinicians contend that, given the likelihood of relapse, the therapy is often long-term.
This perspective is supported by drug manufacturers, who note that the findings "underscore the chronic nature of obesity," akin to managing diseases like high blood pressure.
Patient Accounts
People who have discontinued the medication explain a intense return of appetite.
"It felt as if something that goes on and you become ravenous," said an individual.
This challenge is exacerbated if users have not adopted sustainable lifestyle or habit changes during therapy.
Significant Adoption
Recent estimates show that millions of adults in the UK have used these injections in the last 12 months, with desire remaining high.
- Use is greater among females than males.
- The 40s and 50s demographic shows the greatest usage rates.
- Many access the medications through private healthcare rather than the NHS.
Ultimately, clinicians stress that while the jabs are potent tools for weight loss, they are not a standalone fix and maintained weight loss hinges on integrated behavioural changes.
