A recent study indicates that individuals who come off popular GLP-1 drugs like Wegovy and Mounjaro can put back on reduced body mass far faster than those who stop traditional lifestyle regimens.
Findings released in a prominent health publication demonstrates that while overweight people frequently drop about a fifth of their body weight while using the jabs, the mass is regained at an average rate of nearly a kilo each month after stopping.
"People purchasing such medications must be informed of the potential of rapid weight regain when the medication concludes," warns lead investigator Dr. Susan Jebb.
That rate of regain means a return to original weight within about one and a half years.
Analyzing Treatments
The analysis, which examined 37 of studies involving over 9,000 of patients, contrasted the outcomes of these new drugs with other pills.
The team note that individuals who lose weight through lifestyle changes alone usually experience a more gradual creep back—perhaps 0.1 kg a month—after stopping.
Understanding the Quick Rebound
Experts suggest the mechanism of the jabs accounts for the accelerated rebound.
GLP-1 drugs imitate a natural hormone called GLP-1, which controls feelings of fullness.
"Artificially providing GLP-1 levels far above than normal might result in the system to generate a reduced amount of its own natural GLP-1, and could lessen responsiveness to its actions," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement results in hunger is uncontrolled, making excessive eating much more probable."
An Ongoing Issue?
Health authorities recommend the injections for people with weight-linked medical conditions, alongside prescribed lifestyle changes.
A number of clinicians say that, given the likelihood of weight regain, the therapy should be considered ongoing.
This perspective is reinforced by drug manufacturers, who note that the findings "underscore the chronic character of excess weight," comparing it to managing diseases like hypertension.
Patient Accounts
Users who have come off the jabs describe a sudden resurgence of appetite.
"I experienced a switch flipping and you become starving," recalled a patient.
This challenge is worsened if patients have not developed lasting lifestyle or habit changes during therapy.
Significant Adoption
Recent estimates indicate that a significant number of people in the UK have tried these injections in the last 12 months, with demand continuing to grow.
- Use is more common among women compared to males.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion access the drugs through private healthcare rather than the NHS.
Ultimately, experts stress that while the jabs are powerful tools for shedding pounds, they are not a standalone fix and maintained weight loss likely depends on combined lifestyle support.
