New research indicates that patients who discontinue blockbuster weight-loss injections like Wegovy and Mounjaro can put back on shed pounds much more quickly than those who end traditional lifestyle regimens.
Findings released in a prominent medical journal demonstrates that while obese people often shed about a fifth of their body weight while using the jabs, the mass returns at an estimated rate of nearly a kilo each month after stopping.
"Users using such drugs need to be cognizant of the potential of quick rebound weight gain when the medication ends," stated expert Dr. Susan Jebb.
That rate of regain implies a return to starting weight within about 18 months.
Comparing Treatments
The research, which reviewed 37 of studies involving thousands of patients, contrasted the outcomes of GLP-1 agonists with older methods.
The team emphasize that individuals who lose weight through diet and exercise usually see a more gradual creep back—approximately 100 grams monthly—once they finish.
The Reason for the Quick Rebound
Nutrition scientists propose the mechanism of the drugs accounts for the heightened regain.
GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which controls feelings of fullness.
"Artificially providing the hormone concentrations several times higher than the body's typical production might result in the system to generate a reduced amount of its endogenous hormone, and could lessen sensitivity to its actions," said Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this GLP-1 'fix' leads to appetite is uncontrolled, making overeating far more likely."
A Lifelong Condition?
The NHS suggest the injections for individuals with obesity-related health risks, accompanied by recommended lifestyle changes.
Professionals contend that, given the high risk of weight regain, the treatment might need to be ongoing.
This perspective is reinforced by pharmaceutical companies, who note that the findings "underscore the persistent character of excess weight," comparing it to managing conditions like diabetes.
User Accounts
Users who have stopped the jabs describe a sudden return of hunger.
"It was like a trigger activating and you're instantly extremely hungry," recalled one woman.
This difficulty is worsened if patients have not adopted sustainable lifestyle or habit modifications during therapy.
Significant Use
Survey data suggest that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with desire being substantial.
- Use is higher among women than males.
- The 40s and 50s demographic shows the greatest usage rates.
- Many obtain the drugs through private prescriptions rather than public health services.
In conclusion, clinicians stress that while the jabs are effective tools for weight loss, they are not a magic cure and lasting health benefits relies on combined behavioural management.
