New research suggests that patients who come off blockbuster slimming jabs like Mounjaro or Wegovy tend to recover shed pounds much more quickly than those who halt traditional diet and exercise plans.
Research printed in a prominent health publication points out that while overweight individuals often shed substantial amounts of their total mass while on the medication, the mass comes back at an average rate of 0.8 kg per month after stopping.
"Individuals using these medications need to be aware of the danger of quick rebound weight gain when the therapy concludes," cautioned expert Dr. Susan Jebb.
That rate of recovery implies a reversion to pre-treatment weight within about one and a half years.
Comparing Approaches
The analysis, which reviewed 37 of studies involving over 9,000 of participants, compared the outcomes of the injectable medications with other pills.
Researchers note that individuals who lose weight through dieting usually have a slower creep back—around 0.1 kg a month—post-intervention.
Explaining the Rapid Rebound
Experts suggest the mechanism of the injections accounts for the amplified regain.
The injections imitate a natural hormone called GLP-1, which moderates appetite.
"Long-term administration of GLP-1 levels several times higher than normal may cause the body to produce less of its own natural hormone, and may also reduce responsiveness to its effects," said Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this hormone supplement leads to hunger is uncontrolled, making overeating a significant risk."
A Lifelong Disease?
The NHS advise the jabs for individuals with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
Professionals contend that, given the likelihood of weight regain, the therapy should be considered life-long.
This perspective is reinforced by drug manufacturers, who note that the results "underscore the chronic character of obesity," comparing it to managing conditions like hypertension.
Patient Testimonies
Users who have stopped the jabs describe a intense resurgence of appetite.
"It was like a trigger activating and you're instantly ravenous," recalled an individual.
The struggle is exacerbated if individuals have not developed lasting dietary or behavioural changes during therapy.
Widespread Use
Recent estimates suggest that a significant number of adults in the UK have used weight-loss jabs in the last 12 months, with desire continuing to grow.
- Use is greater among women than men.
- The 40s and 50s demographic shows the highest level of interest.
- Many obtain the drugs through private healthcare rather than the NHS.
Ultimately, clinicians emphasize that while these medications are potent agents for shedding pounds, they are not a standalone fix and maintained weight loss likely depends on combined behavioural management.
