A recent study suggests that patients who stop using new GLP-1 drugs like Wegovy and Mounjaro may regain shed pounds at a significantly accelerated pace than those who halt traditional lifestyle regimens.
Findings released in a major health publication demonstrates that while obese people frequently drop a large proportion of their total mass while undergoing treatment, the mass is regained at an estimated rate of 0.8 kg per month once they quit.
"Users using these medications must be cognizant of the danger of rapid rebound weight gain when the medication concludes," warns researcher Dr. Susan Jebb.
Such speed of recovery implies a reversion to pre-treatment weight within about a year and a half.
Weighing Therapies
The study, which examined dozens of studies involving over 9,000 of patients, compared the effects of GLP-1 agonists with other pills.
Researchers emphasize that individuals who shed pounds through dieting typically have a more gradual creep back—perhaps 0.1 kg a month—once they finish.
Understanding the Rapid Rebound
Doctors suggest the way of the injections is key to understanding the amplified rebound.
GLP-1 drugs mimic a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Sustained high doses of the hormone levels several times higher than the body's typical production might result in the body to produce less of its endogenous hormone, and may also reduce sensitivity to its actions," said Dr. Adam Collins, a dietetics researcher.
"Stopping of this GLP-1 'fix' results in appetite is no longer kept in check, making excessive eating a significant risk."
An Ongoing Disease?
The NHS suggest the injections for individuals with obesity-related health risks, accompanied by prescribed lifestyle changes.
Professionals argue that, due to the likelihood of weight regain, the treatment should be considered life-long.
This opinion is echoed by drug manufacturers, who state that the findings "highlight the persistent nature of obesity," comparing it to managing conditions like hypertension.
User Accounts
Individuals who have come off the medication describe a sudden return of cravings.
"It was like a trigger that goes on and you become extremely hungry," said one woman.
The struggle is compounded if patients have not developed permanent dietary or behavioural modifications during treatment.
Growing Adoption
Recent estimates show that millions of people in the UK have used these injections in the past year, with interest continuing to grow.
- Use is greater among women than males.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion access the drugs through private healthcare rather than the NHS.
Finally, experts caution that while the jabs are effective agents for weight loss, they are not a standalone solution and lasting health benefits hinges on combined lifestyle management.
