New research reveals that people who come off popular GLP-1 drugs like Mounjaro or Wegovy tend to recover lost weight far faster than those who halt conventional lifestyle regimens.
Research printed in a leading medical journal points out that while overweight people frequently drop substantial amounts of their body weight while using the jabs, the weight is regained at an average rate of 0.8 kg per month upon discontinuation.
"People purchasing these treatments should be informed of the danger of quick rebound weight gain when the treatment concludes," stated researcher Dr. Susan Jebb.
That rate of recovery implies a return to original weight within about a year and a half.
Analyzing Treatments
The study, which examined dozens of studies involving thousands of patients, contrasted the results of these new drugs with older methods.
The team note that people who lose weight through dieting usually see a more gradual weight regain—perhaps 0.1 kg a month—after stopping.
Understanding the Quick Regain
Doctors suggest the mechanism of the jabs explains the heightened regain.
These medications copy a body's own chemical called glucagon-like peptide-1, which moderates appetite.
"Sustained high doses of the hormone concentrations several times higher than the body's typical production might result in the system to generate a reduced amount of its own natural GLP-1, and could reduce responsiveness to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this hormone supplement means hunger is no longer kept in check, making binge eating a significant risk."
A Chronic Condition?
Health authorities advise the injections for people with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians contend that, considering the high risk of relapse, the therapy might need to be life-long.
This opinion is reinforced by drug manufacturers, who note that the findings "emphasize the chronic nature of excess weight," comparing it to managing diseases like high blood pressure.
User Accounts
People who have stopped the medication describe a powerful return of appetite.
"It was like a trigger that goes on and you become starving," said an individual.
This challenge is compounded if users have not developed sustainable dietary or behavioural changes during treatment.
Significant Use
Recent estimates show that a significant number of adults in the UK have used weight-loss jabs in the last 12 months, with interest continuing to grow.
- Adoption is more common among females than males.
- The middle-aged age group shows the highest level of interest.
- Many access the drugs through private healthcare rather than public health services.
Ultimately, researchers stress that while the jabs are powerful agents for weight loss, they are not a magic solution and long-term success hinges on combined lifestyle changes.
