Fresh analysis suggests that patients who discontinue popular weight-loss injections like semaglutide or tirzepatide tend to recover shed pounds much more quickly than those who end traditional lifestyle plans.
Published data in a prominent medical journal demonstrates that while obese individuals frequently drop substantial amounts 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 buying such drugs need to be cognizant of the risk of fast rebound weight gain when the medication ends," cautioned lead investigator Dr. Susan Jebb.
This pace of regain means a return to starting weight within about one and a half years.
Weighing Therapies
The research, which reviewed dozens of trials involving thousands of participants, contrasted the effects of the injectable medications with other pills.
Scientists emphasize that people who shed pounds through dieting generally experience a less rapid creep back—approximately 0.1 kg a month—once they finish.
Understanding the Fast Rebound
Nutrition scientists believe the mechanism of the drugs explains the heightened rebound.
GLP-1 drugs imitate a body's own chemical called GLP-1, which moderates feelings of fullness.
"Artificially providing the hormone concentrations far above than the body's typical production could lead to the body to generate a reduced amount of its endogenous GLP-1, and may also reduce responsiveness to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this GLP-1 'fix' leads to appetite is unsuppressed, making binge eating far more likely."
An Ongoing Disease?
Health authorities recommend the jabs for people with obesity-related medical conditions, accompanied by recommended lifestyle changes.
Many experts contend that, considering the likelihood of relapse, the therapy might need to be life-long.
This opinion is echoed by drug manufacturers, who note that the findings "underscore the long-term nature of obesity," similar to managing diseases like hypertension.
Patient Testimonies
Users who have come off the jabs report a intense return of hunger.
"I experienced something flipping and you become extremely hungry," described a patient.
The struggle is compounded if patients have not established sustainable lifestyle or habit modifications during therapy.
Widespread Use
Recent estimates indicate that millions of people in the UK have used weight-loss jabs in the past year, with desire remaining high.
- Adoption is greater among women than men.
- The 40s and 50s demographic shows the greatest usage rates.
- Many obtain the drugs through private healthcare rather than public health services.
In conclusion, researchers stress that while the jabs are potent agents for shedding pounds, they are not a standalone cure and lasting health benefits hinges on combined lifestyle support.
