New research indicates that patients who discontinue new weight-loss injections like Wegovy and Mounjaro may regain lost weight far faster than those who end traditional diet and exercise plans.
Research printed in a prominent health publication points out that while obese individuals frequently drop a large proportion of their body weight while on the medication, the mass is regained at an average rate of nearly a kilo each month upon discontinuation.
"Users using these treatments should be cognizant of the danger of fast rebound weight gain when the medication concludes," cautioned researcher Dr. Susan Jebb.
That rate of regain means a return to pre-treatment weight in about 18 months.
Analyzing Treatments
The research, which reviewed dozens of studies involving thousands of participants, compared the outcomes of these new drugs with other pills.
Scientists point out that individuals who shed pounds through dieting typically see a less rapid creep back—perhaps 100 grams monthly—post-intervention.
Understanding the Rapid Regain
Doctors suggest the mechanism of the drugs accounts for the accelerated weight return.
The injections copy a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Long-term administration of GLP-1 concentrations far above than normal may cause the system to produce less of its own natural hormone, and may also diminish sensitivity to its actions," said Dr. Adam Collins, a nutrition specialist.
"Stopping of this GLP-1 'fix' results in hunger is unsuppressed, making excessive eating a significant risk."
A Chronic Condition?
Health authorities advise the jabs for individuals with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
Many experts argue that, given the high risk of relapse, the treatment should be considered life-long.
This perspective is echoed by pharmaceutical companies, who state that the findings "highlight the long-term nature of excess weight," comparing it to managing conditions like hypertension.
Patient Experiences
Individuals who have discontinued the jabs report a intense return of appetite.
"It was like something flipping and you're instantly extremely hungry," said one woman.
This difficulty is compounded if individuals have not adopted lasting lifestyle or habit changes during therapy.
Widespread Adoption
Survey data suggest that millions of people in the UK have tried these injections in the past year, with demand continuing to grow.
- Adoption is greater among women compared to men.
- The middle-aged demographic shows the greatest level of interest.
- Many obtain the medications through private prescriptions rather than the NHS.
In conclusion, researchers emphasize that while the jabs are effective tools for weight loss, they are not a permanent solution and maintained weight loss likely depends on ongoing behavioural management.
