A recent study suggests that individuals who come off blockbuster GLP-1 drugs like Mounjaro or Wegovy may regain shed pounds much more quickly than those who end conventional lifestyle regimens.
Research printed in a leading medical journal shows that while obese people often shed about a fifth of their total mass while using the jabs, the weight comes back at an estimated rate of nearly a kilo each month once they quit.
"Users using such treatments must be cognizant of the danger of fast weight regain when the medication ends," stated expert Dr. Susan Jebb.
Such speed of recovery means a return to original weight in about 18 months.
Comparing Therapies
The study, which reviewed 37 of trials involving thousands of participants, contrasted the outcomes of these new drugs with older methods.
The team note that individuals who lose weight through lifestyle changes alone generally experience a slower creep back—perhaps 100 grams monthly—once they finish.
The Reason for the Rapid Regain
Doctors suggest the mode of action of the jabs is key to understanding the accelerated regain.
The injections copy a natural hormone called glucagon-like peptide-1, which moderates feelings of fullness.
"Sustained high doses of GLP-1 concentrations far above than the body's typical production may cause the system to produce less of its endogenous GLP-1, and may also diminish sensitivity to its effects," said Dr. Adam Collins, a nutrition expert.
"Withdrawal of this medication leads to hunger is no longer kept in check, making excessive eating far more likely."
A Chronic Disease?
Medical guidelines advise the jabs for individuals with obesity-related health risks, accompanied by prescribed diet and exercise modifications.
A number of clinicians argue that, given the likelihood of weight regain, the treatment might need to be long-term.
This perspective is echoed by pharmaceutical companies, who say that the findings "emphasize the chronic nature of excess weight," akin to managing diseases like high blood pressure.
User Experiences
Users who have come off the jabs describe a intense return of cravings.
"I experienced a switch that goes on and you become starving," said a patient.
This difficulty is worsened if patients have not adopted sustainable dietary or behavioural changes during therapy.
Growing Interest
Survey data suggest that millions of adults in the UK have tried weight-loss jabs in the past year, with interest remaining high.
- Use is higher among females than men.
- The 40s and 50s age group shows the highest usage rates.
- Many access the drugs through private healthcare rather than public health services.
In conclusion, researchers emphasize that while these medications are potent agents for shedding pounds, they are not a magic solution and long-term success likely depends on combined lifestyle support.
