Fresh analysis suggests that individuals who stop using popular weight-loss injections like Mounjaro or Wegovy tend to recover shed pounds much more quickly than those who end traditional lifestyle programs.
Findings released in a prominent medical journal points out that while overweight people frequently drop a large proportion of their total mass while undergoing treatment, the weight is regained at an estimated rate of nearly a kilo each month after stopping.
"People purchasing such drugs need to be aware of the danger of fast weight regain when the treatment concludes," stated expert Dr. Susan Jebb.
That rate of recovery implies a return to pre-treatment weight in about one and a half years.
Weighing Approaches
The research, which reviewed dozens of studies involving thousands of participants, contrasted the effects of these new drugs with conventional dieting.
Researchers emphasize that individuals who lose weight through diet and exercise usually have a more gradual weight regain—around 100 grams monthly—after stopping.
Understanding the Rapid Regain
Experts believe the mechanism of the drugs is key to understanding the heightened rebound.
These medications mimic a natural hormone called glucagon-like peptide-1, which controls feelings of fullness.
"Sustained high doses of GLP-1 levels several times higher than normal might result in the system to produce less of its endogenous GLP-1, and could lessen sensitivity to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this medication leads to hunger is uncontrolled, making binge eating far more likely."
A Chronic Issue?
Medical guidelines advise the injections for individuals with weight-linked health risks, alongside prescribed diet and exercise modifications.
A number of clinicians contend that, considering the likelihood of relapse, the therapy might need to be ongoing.
This view is echoed by drug manufacturers, who say that the findings "emphasize the long-term character of obesity," comparing it to managing conditions like high blood pressure.
Patient Accounts
Individuals who have discontinued the jabs explain a sudden resurgence of cravings.
"It was like a switch flipping and you're instantly ravenous," described an individual.
This difficulty is exacerbated if individuals have not adopted sustainable lifestyle or habit modifications during therapy.
Significant Interest
Recent estimates suggest that millions of people in the UK have tried these injections in the past year, with demand continuing to grow.
- Use is more common among women compared to men.
- The middle-aged demographic shows the highest level of interest.
- Many obtain the medications through private healthcare rather than the NHS.
Ultimately, clinicians caution that while GLP-1 drugs are potent agents for weight loss, they are not a magic cure and maintained weight loss relies on ongoing behavioural support.
