Fresh analysis reveals that individuals who come off blockbuster GLP-1 drugs like Wegovy and Mounjaro can put back on reduced body mass much more quickly than those who halt traditional lifestyle programs.
Research printed in a major health publication points out that while overweight people frequently drop substantial amounts of their total mass while using the jabs, the weight returns at an average rate of nearly a kilo each month once they quit.
"Users using these medications must be aware of the danger of quick weight regain when the medication is stopped," stated lead investigator Dr. Susan Jebb.
Such speed of regain means a reversion to original mass in about a year and a half.
Weighing Approaches
The research, which examined dozens of trials involving over 9,000 of patients, compared the results of these new drugs with other pills.
The team emphasize that people who lose weight through diet and exercise typically experience a slower weight regain—around 0.1 kg a month—after stopping.
Understanding the Fast Rebound
Doctors believe the way of the injections explains the heightened weight return.
The injections mimic a natural hormone called glucagon-like peptide-1, which moderates feelings of fullness.
"Sustained high doses of the hormone concentrations several times higher than normal might result in the system to generate a reduced amount of its endogenous hormone, and could lessen sensitivity to its effects," noted Dr. Adam Collins, a nutrition expert.
"Discontinuation of this GLP-1 'fix' results in hunger is no longer kept in check, making overeating much more probable."
A Chronic Issue?
The NHS suggest the injections for people with obesity-related health risks, alongside prescribed diet and exercise modifications.
A number of clinicians argue that, considering the high risk of relapse, the therapy might need to be long-term.
This opinion is reinforced by drug manufacturers, who note that the findings "highlight the persistent nature of excess weight," similar to managing diseases like high blood pressure.
User Accounts
People who have discontinued the jabs report a intense return of appetite.
"I experienced a trigger that goes on and you become extremely hungry," described one woman.
The struggle is worsened if patients have not developed lasting dietary or behavioural modifications during therapy.
Widespread Use
Figures suggest that a significant number of people in the UK have tried these injections in the past year, with desire remaining high.
- Adoption is greater among women compared to males.
- The middle-aged demographic shows the greatest usage rates.
- A large proportion access the drugs through private prescriptions rather than the NHS.
In conclusion, experts stress that while GLP-1 drugs are potent agents for weight loss, they are not a magic solution and long-term success relies on combined lifestyle management.
