New research suggests that people who come off blockbuster slimming jabs like Mounjaro or Wegovy can put back on shed pounds far faster than those who stop traditional lifestyle regimens.
Research printed in a prominent health publication shows that while obese individuals often shed substantial amounts of their total mass while undergoing treatment, the weight comes back at an average rate of nearly a kilo each month once they quit.
"People using such drugs must be cognizant of the potential of quick weight regain when the therapy concludes," warns lead investigator Dr. Susan Jebb.
Such speed of recovery implies a reversion to original weight in about 18 months.
Weighing Approaches
The research, which examined dozens of studies involving thousands of participants, compared the results of these new drugs with conventional dieting.
Scientists emphasize that individuals who lose weight through lifestyle changes alone typically experience a less rapid creep back—perhaps 0.1 kg a month—post-intervention.
Explaining the Fast Rebound
Nutrition scientists propose the way of the drugs accounts for the amplified weight return.
GLP-1 drugs mimic a natural hormone called glucagon-like peptide-1, which controls hunger.
"Long-term administration of the hormone concentrations far above than normal might result in the body to generate a reduced amount of its own natural GLP-1, and may also diminish sensitivity to its effects," explained Dr. Adam Collins, a dietetics researcher.
"Stopping of this GLP-1 'fix' leads to appetite is uncontrolled, making overeating far more likely."
An Ongoing Condition?
Health authorities recommend the jabs for people with obesity-related health risks, alongside prescribed diet and exercise modifications.
Professionals contend that, due to the high risk of weight regain, the treatment should be considered long-term.
This perspective is reinforced by pharmaceutical companies, who say that the findings "highlight the persistent nature of obesity," similar to managing conditions like hypertension.
Patient Testimonies
People who have stopped the medication describe a intense resurgence of hunger.
"It was like something that goes on and I was suddenly starving," said one woman.
The struggle is worsened if individuals have not established sustainable lifestyle or habit changes during therapy.
Significant Use
Recent estimates indicate that millions of adults in the UK have used these injections in the last 12 months, with demand remaining high.
- Use is more common among women than men.
- The 40s and 50s demographic shows the highest level of interest.
- Many access the medications through private healthcare rather than the NHS.
Finally, experts stress that while the jabs are potent tools for shedding pounds, they are not a magic cure and lasting health benefits likely depends on combined behavioural management.
