A recent study reveals that people who come off new GLP-1 drugs like Mounjaro or Wegovy tend to recover shed pounds far faster than those who stop conventional lifestyle programs.
Findings released in a leading medical journal demonstrates that while obese people frequently drop substantial amounts of their total mass while on the medication, the mass returns at an average rate of nearly a kilo each month once they quit.
"Users using these treatments should be cognizant of the potential of rapid weight regain when the treatment concludes," cautioned lead investigator Dr. Susan Jebb.
That rate of recovery means a reversion to pre-treatment weight in about one and a half years.
Weighing Therapies
The research, which reviewed dozens of trials involving thousands of patients, contrasted the outcomes of GLP-1 agonists with other pills.
Scientists point out that individuals who shed pounds through lifestyle changes alone generally have a less rapid creep back—around 0.1 kg a month—once they finish.
Understanding the Quick Rebound
Doctors propose the mode of action of the injections is key to understanding the amplified regain.
The injections mimic a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 concentrations far above than the body's typical production might result in the body to generate a reduced amount of its own natural hormone, and may also lessen responsiveness to its effects," noted Dr. Adam Collins, a dietetics researcher.
"Stopping of this hormone supplement results in appetite is no longer kept in check, making overeating a significant risk."
A Chronic Issue?
Health authorities recommend the jabs for people with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
A number of clinicians argue that, given the high risk of relapse, the therapy should be considered life-long.
This perspective is echoed by pharmaceutical companies, who say that the results "highlight the chronic nature of excess weight," comparing it to managing diseases like hypertension.
User Accounts
Individuals who have come off the jabs explain a intense return of hunger.
"It was like a trigger activating and you become ravenous," described an individual.
This difficulty is worsened if users have not developed lasting dietary or behavioural modifications during therapy.
Growing Interest
Survey data show that millions of people in the UK have tried weight-loss jabs in the past year, with desire remaining high.
- Use is more common among females compared to men.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion obtain the medications through private prescriptions rather than public health services.
Finally, experts caution that while the jabs are potent tools for weight loss, they are not a standalone fix and lasting health benefits likely depends on integrated lifestyle changes.
