A recent study reveals that patients who come off new weight-loss injections like Wegovy and Mounjaro tend to recover reduced body mass far faster than those who end traditional lifestyle programs.
Research printed in a major health publication shows that while obese individuals frequently drop about a fifth of their total mass while undergoing treatment, the weight returns at an estimated rate of 0.8 kg per month once they quit.
"Individuals using such drugs must be cognizant of the potential of quick weight regain when the therapy concludes," stated expert Dr. Susan Jebb.
This pace of recovery suggests a reversion to starting mass within about 18 months.
Weighing Approaches
The research, which reviewed dozens of trials involving thousands of participants, contrasted the results of these new drugs with other pills.
Researchers emphasize that people who lose weight through dieting generally have a slower weight regain—around 100 grams monthly—after stopping.
Understanding the Rapid Regain
Doctors propose the way of the jabs is key to understanding the amplified regain.
GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which helps regulate hunger.
"Long-term administration of the hormone levels several times higher than the body's typical production may cause the system to generate a reduced amount of its own natural GLP-1, and could reduce responsiveness to its actions," said Dr. Adam Collins, a nutrition specialist.
"Stopping of this hormone supplement means appetite is uncontrolled, making excessive eating a significant risk."
An Ongoing Issue?
The NHS suggest the jabs for people with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
Professionals say that, due to the significant potential of weight regain, the therapy might need to be ongoing.
This view is reinforced by drug manufacturers, who state that the findings "emphasize the chronic character of excess weight," akin to managing conditions like diabetes.
Patient Testimonies
Individuals who have discontinued the medication describe a powerful return of cravings.
"I experienced something that goes on and I was suddenly starving," described one woman.
This challenge is worsened if individuals have not developed sustainable dietary or behavioural modifications during therapy.
Widespread Adoption
Recent estimates suggest that a significant number of adults in the UK have tried these injections in the past year, with demand being substantial.
- Adoption is higher among females than men.
- The 40s and 50s age group shows the greatest usage rates.
- Many obtain the drugs through private prescriptions rather than the NHS.
In conclusion, researchers caution that while these medications are effective agents for weight loss, they are not a standalone solution and maintained weight loss likely depends on integrated behavioural support.
