Fresh analysis indicates that people who discontinue blockbuster weight-loss injections like Mounjaro or Wegovy may regain shed pounds far faster than those who stop conventional lifestyle programs.
Research printed in a prominent health publication points out that while overweight people can lose about a fifth of their total mass while on the medication, the weight is regained at an estimated rate of nearly a kilo each month upon discontinuation.
"Individuals buying such drugs need to be aware of the potential of quick rebound weight gain when the medication concludes," cautioned expert Dr. Susan Jebb.
This pace of regain suggests a return to pre-treatment weight within about 18 months.
Weighing Approaches
The analysis, which examined dozens of studies involving thousands of participants, contrasted the outcomes of these new drugs with conventional dieting.
Researchers emphasize that individuals who shed pounds through diet and exercise usually see a less rapid creep back—approximately 0.1 kg a month—post-intervention.
Understanding the Fast Regain
Nutrition scientists believe the mechanism of the jabs accounts for the accelerated weight return.
The injections imitate a natural hormone called GLP-1, which controls appetite.
"Sustained high doses of GLP-1 levels several times higher than normal may cause the system to produce less of its endogenous GLP-1, and may also reduce responsiveness to its effects," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this GLP-1 'fix' leads to hunger is uncontrolled, making excessive eating a significant risk."
A Lifelong Issue?
Health authorities suggest the jabs for people with obesity-related medical conditions, alongside recommended lifestyle changes.
A number of clinicians argue that, considering the significant potential of relapse, the treatment might need to be long-term.
This opinion is reinforced by pharmaceutical companies, who note that the findings "underscore the long-term character of excess weight," comparing it to managing conditions like diabetes.
User Experiences
Users who have stopped the jabs describe a intense resurgence of appetite.
"It was like a switch that goes on and you become extremely hungry," recalled a patient.
This difficulty is compounded if patients have not adopted permanent lifestyle or habit modifications during therapy.
Significant Adoption
Survey data indicate 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 women than males.
- The middle-aged demographic shows the greatest level of interest.
- Many obtain the medications through private prescriptions rather than the NHS.
Finally, experts emphasize that while the jabs are potent tools for shedding pounds, they are not a magic cure and maintained weight loss likely depends on integrated behavioural management.
