Fresh analysis reveals that people who stop using new GLP-1 drugs like Mounjaro or Wegovy tend to recover reduced body mass at a significantly accelerated pace than those who stop traditional diet and exercise regimens.
Findings released in a prominent medical journal points out that while obese people frequently drop a large proportion of their body weight while undergoing treatment, the weight comes back at an estimated rate of 0.8 kg per month after stopping.
"Individuals purchasing these drugs must be informed of the risk of fast weight regain when the therapy concludes," stated lead investigator Dr. Susan Jebb.
That rate of recovery implies a return to starting weight in about one and a half years.
Comparing Treatments
The research, which examined 37 of studies involving thousands of participants, compared the effects of these new drugs with other pills.
The team emphasize that individuals who lose weight through dieting usually experience a less rapid weight regain—perhaps 0.1 kg a month—post-intervention.
Explaining the Quick Regain
Doctors suggest the mechanism of the drugs accounts for the amplified weight return.
These medications mimic a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of the hormone concentrations several times higher than normal might result in the body to generate a reduced amount of its own natural hormone, and may also diminish responsiveness to its actions," said Dr. Adam Collins, a dietetics expert.
"Withdrawal of this hormone supplement means appetite is uncontrolled, making overeating much more probable."
An Ongoing Disease?
Health authorities recommend the injections for people with weight-linked medical conditions, alongside recommended lifestyle changes.
Professionals say that, given the significant potential of weight regain, the therapy is often long-term.
This opinion is reinforced by pharmaceutical companies, who state that the findings "underscore the persistent nature of excess weight," akin to managing diseases like diabetes.
User Testimonies
Users who have stopped the medication report a intense resurgence of cravings.
"It felt as if something flipping and you're instantly ravenous," described an individual.
This challenge is exacerbated if patients have not established permanent dietary or behavioural changes during treatment.
Widespread Interest
Recent estimates suggest that millions of adults in the UK have tried these injections in the last 12 months, with desire continuing to grow.
- Use is more common among females compared to males.
- The middle-aged age group shows the highest level of interest.
- A large proportion access the medications through private prescriptions rather than public health services.
Finally, experts emphasize that while GLP-1 drugs are effective tools for shedding pounds, they are not a standalone fix and maintained weight loss likely depends on integrated behavioural support.
