A recent study indicates that patients who come off new weight-loss injections like Mounjaro or Wegovy tend to recover reduced body mass much more quickly than those who end conventional diet and exercise plans.
Findings released in a leading medical journal points out that while obese individuals frequently drop about a fifth of their total mass while on the medication, the weight comes back at an average rate of 0.8 kg per month once they quit.
"Users purchasing such drugs need to be aware of the risk of quick weight regain when the medication is stopped," cautioned expert Dr. Susan Jebb.
This pace of regain implies a return to starting mass within about 18 months.
Weighing Treatments
The analysis, which reviewed 37 of trials involving thousands of patients, compared the results of GLP-1 agonists with conventional dieting.
Researchers point out that individuals who lose weight through diet and exercise typically see a slower creep back—around 100 grams monthly—post-intervention.
The Reason for the Rapid Regain
Doctors propose the way of the jabs accounts for the amplified rebound.
These medications imitate a natural hormone called GLP-1, which moderates appetite.
"Artificially providing GLP-1 concentrations several times higher than the body's typical production may cause the body to produce less of its own natural GLP-1, and could diminish responsiveness to its actions," noted Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this hormone supplement means hunger is unsuppressed, making excessive eating much more probable."
An Ongoing Disease?
The NHS advise the injections for people with obesity-related health risks, alongside recommended lifestyle changes.
A number of clinicians say that, given the significant potential of weight regain, the therapy should be considered long-term.
This opinion is supported by drug manufacturers, who say that the findings "emphasize the chronic character of obesity," akin to managing conditions like high blood pressure.
Patient Testimonies
People who have come off the medication describe a intense resurgence of appetite.
"It was like a trigger that goes on and you're instantly starving," recalled one woman.
This challenge is compounded if patients have not established sustainable dietary or behavioural changes during treatment.
Significant Use
Figures indicate that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with desire being substantial.
- Use is more common among women than males.
- The middle-aged demographic shows the greatest usage rates.
- A large proportion access the drugs through private prescriptions rather than public health services.
Ultimately, clinicians stress that while these medications are powerful agents for shedding pounds, they are not a permanent cure and lasting health benefits relies on combined lifestyle changes.
