A recent study indicates that people who come off blockbuster slimming jabs like Wegovy and Mounjaro can put back on shed pounds far faster than those who end conventional diet and exercise regimens.
Published data in a prominent health publication shows that while overweight people frequently drop substantial amounts of their body weight while undergoing treatment, the weight is regained at an average rate of nearly a kilo each month upon discontinuation.
"Users using these medications must be cognizant of the danger of fast weight regain when the treatment ends," warns expert Dr. Susan Jebb.
That rate of recovery means a reversion to pre-treatment mass within about one and a half years.
Comparing Approaches
The analysis, which examined 37 of trials involving thousands of participants, compared the effects of GLP-1 agonists with older methods.
Scientists point out that individuals who lose weight through lifestyle changes alone typically see a slower weight regain—perhaps 0.1 kg a month—post-intervention.
Explaining the Rapid Regain
Experts believe the mode of action of the drugs is key to understanding the heightened regain.
GLP-1 drugs copy a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Long-term administration of the hormone levels far above than normal might result in the body to generate a reduced amount of its own natural hormone, and may also lessen responsiveness to its actions," noted Dr. Adam Collins, a dietetics expert.
"Stopping of this hormone supplement means hunger is no longer kept in check, making overeating a significant risk."
An Ongoing Disease?
The NHS suggest the jabs for people with weight-linked health risks, accompanied by recommended lifestyle changes.
Professionals contend that, considering the significant potential of weight regain, the treatment might need to be long-term.
This perspective is reinforced by pharmaceutical companies, who say that the results "emphasize the long-term character of excess weight," comparing it to managing diseases like high blood pressure.
Patient Experiences
People who have come off the jabs report a intense resurgence of hunger.
"It felt as if something flipping and I was suddenly starving," described an individual.
This challenge is compounded if patients have not established lasting dietary or behavioural changes during treatment.
Growing Use
Recent estimates indicate that a significant number of people in the UK have used weight-loss jabs in the past year, with interest being substantial.
- Use is higher among women compared to males.
- The middle-aged age group shows the highest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
In conclusion, clinicians stress that while these medications are effective tools for weight loss, they are not a standalone cure and lasting health benefits relies on integrated behavioural management.
