Fresh analysis suggests that individuals who discontinue new weight-loss injections like Wegovy and Mounjaro can put back on lost weight much more quickly than those who halt traditional diet and exercise regimens.
Findings released in a major health publication demonstrates that while overweight people can lose substantial amounts of their body weight while using the jabs, the mass comes back at an estimated rate of 0.8 kg per month once they quit.
"People using these medications need to be informed of the danger of fast weight regain when the therapy ends," cautioned researcher Dr. Susan Jebb.
Such speed of recovery suggests a reversion to original mass within about one and a half years.
Comparing Therapies
The analysis, which examined dozens of trials involving thousands of participants, contrasted the outcomes of the injectable medications with older methods.
The team point out that individuals who lose weight through dieting typically see a more gradual creep back—approximately 0.1 kg a month—post-intervention.
Explaining the Quick Rebound
Experts believe the mode of action of the jabs accounts for the amplified weight return.
These medications copy a body's own chemical called GLP-1, which moderates appetite.
"Long-term administration of GLP-1 concentrations far above than normal may cause the system to generate a reduced amount of its own natural hormone, and could diminish sensitivity to its actions," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this medication means appetite is no longer kept in check, making excessive eating a significant risk."
A Chronic Issue?
The NHS suggest the injections for people with weight-linked medical conditions, alongside prescribed lifestyle changes.
A number of clinicians contend that, given the significant potential of weight regain, the therapy is often ongoing.
This perspective is reinforced by pharmaceutical companies, who state that the results "underscore the chronic nature of excess weight," comparing it to managing diseases like high blood pressure.
Patient Experiences
Users who have stopped the medication report a intense resurgence of appetite.
"It felt as if a switch flipping and you become starving," recalled one woman.
The struggle is worsened if users have not developed permanent lifestyle or habit modifications during therapy.
Growing Adoption
Recent estimates indicate that millions of adults in the UK have tried these injections in the past year, with interest continuing to grow.
- Use is greater among women than males.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion access the drugs through private prescriptions rather than public health services.
Finally, researchers emphasize that while the jabs are effective agents for shedding pounds, they are not a standalone cure and long-term success relies on combined behavioural management.
