A recent study indicates that patients who come off popular weight-loss injections like Wegovy and Mounjaro tend to recover lost weight at a significantly accelerated pace than those who end traditional diet and exercise programs.
Research printed in a prominent medical journal demonstrates that while overweight people can lose substantial amounts of their total mass while undergoing treatment, the weight comes back at an average rate of nearly a kilo each month upon discontinuation.
"People purchasing such treatments need to be informed of the danger of fast weight regain when the medication is stopped," stated lead investigator Dr. Susan Jebb.
Such speed of regain implies a return to original mass within about one and a half years.
Weighing Treatments
The research, which looked at dozens of studies involving thousands of patients, compared the effects of the injectable medications with conventional dieting.
Scientists emphasize that individuals who shed pounds through lifestyle changes alone typically see a more gradual weight regain—perhaps 100 grams monthly—post-intervention.
Explaining the Quick Rebound
Doctors believe the mechanism of the drugs accounts for the accelerated regain.
GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which moderates feelings of fullness.
"Artificially providing the hormone concentrations far above than the body's typical production may cause the system to produce less of its own natural GLP-1, and could lessen sensitivity to its effects," noted Dr. Adam Collins, a nutrition expert.
"Withdrawal of this hormone supplement means hunger is uncontrolled, making excessive eating much more probable."
An Ongoing Condition?
Health authorities recommend the injections for people with obesity-related health risks, accompanied by prescribed lifestyle changes.
Many experts argue that, given the high risk of weight regain, the therapy should be considered ongoing.
This view is echoed by drug manufacturers, who note that the results "underscore the long-term character of obesity," akin to managing diseases like high blood pressure.
Patient Experiences
People who have come off the jabs describe a intense return of cravings.
"It felt as if a trigger activating and you're instantly starving," recalled one woman.
This difficulty is worsened if patients have not adopted permanent lifestyle or habit modifications during therapy.
Widespread Interest
Recent estimates show that millions of adults in the UK have tried weight-loss jabs in the past year, with interest remaining high.
- Adoption is greater among women than men.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion access the drugs through private healthcare rather than the NHS.
Ultimately, researchers stress that while GLP-1 drugs are powerful agents for weight loss, they are not a magic cure and lasting health benefits hinges on combined lifestyle changes.
