A recent study reveals that people who stop using new GLP-1 drugs like Wegovy and Mounjaro can put back on reduced body mass at a significantly accelerated pace than those who halt conventional lifestyle regimens.
Findings released in a major medical journal points out that while overweight individuals can lose about a fifth of their body weight while using the jabs, the mass returns at an average rate of nearly a kilo each month after stopping.
"Individuals using such treatments need to be cognizant of the danger of rapid weight regain when the therapy concludes," stated expert Dr. Susan Jebb.
That rate of recovery implies a reversion to original mass within about one and a half years.
Comparing Approaches
The study, which reviewed 37 of trials involving thousands of participants, contrasted the effects of GLP-1 agonists with other pills.
The team emphasize that individuals who lose weight through diet and exercise typically have a less rapid weight regain—perhaps 100 grams monthly—post-intervention.
Understanding the Quick Regain
Doctors suggest the way of the drugs is key to understanding the heightened weight return.
These medications imitate a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 concentrations several times higher than the body's typical production might result in the system to generate a reduced amount of its endogenous GLP-1, and may also diminish responsiveness to its actions," noted Dr. Adam Collins, a nutrition expert.
"Withdrawal of this medication leads to hunger is uncontrolled, making overeating far more likely."
A Lifelong Issue?
Medical guidelines suggest the jabs for people with obesity-related medical conditions, alongside recommended lifestyle changes.
Many experts say that, given the significant potential of weight regain, the therapy should be considered ongoing.
This perspective is reinforced by drug manufacturers, who say that the findings "emphasize the persistent nature of excess weight," similar to managing diseases like hypertension.
User Testimonies
People who have discontinued the jabs describe a intense return of cravings.
"It felt as if a switch activating and you're instantly extremely hungry," said one woman.
The struggle is worsened if patients have not established lasting dietary or behavioural changes during therapy.
Widespread Adoption
Survey data show that a significant number of people in the UK have tried these injections in the past year, with demand being substantial.
- Adoption is more common among women compared to men.
- The middle-aged demographic shows the highest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
Finally, experts emphasize that while GLP-1 drugs are powerful tools for weight loss, they are not a permanent cure and long-term success relies on combined lifestyle support.
