Fresh analysis reveals that people who stop using new weight-loss injections like semaglutide or tirzepatide may regain reduced body mass far faster than those who stop traditional lifestyle programs.
Research printed in a major medical journal points out that while obese individuals often shed about a fifth of their body weight while undergoing treatment, the weight returns at an average rate of 0.8 kg per month after stopping.
"Users using such medications should be cognizant of the danger of fast weight regain when the medication ends," warns expert Dr. Susan Jebb.
That rate of regain implies a return to original mass within about 18 months.
Analyzing Therapies
The research, which examined dozens of studies involving thousands of participants, contrasted the outcomes of the injectable medications with older methods.
Researchers emphasize that people who shed pounds through diet and exercise usually experience a less rapid weight regain—approximately 0.1 kg a month—post-intervention.
The Reason for the Rapid Rebound
Nutrition scientists propose the mode of action of the injections explains the accelerated regain.
GLP-1 drugs mimic a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of the hormone levels several times higher than normal might result in the system to produce less of its own natural GLP-1, and may also diminish responsiveness to its actions," said Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this medication results in appetite is no longer kept in check, making binge eating much more probable."
A Chronic Disease?
The NHS advise the jabs for individuals with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
Many experts contend that, given the likelihood of weight regain, the therapy is often life-long.
This view is supported by drug manufacturers, who say that the results "emphasize the persistent nature of excess weight," comparing it to managing conditions like high blood pressure.
User Testimonies
People who have come off the jabs explain a intense return of hunger.
"I experienced something activating and I was suddenly extremely hungry," said a patient.
This challenge is compounded if individuals have not developed permanent lifestyle or habit changes during therapy.
Significant Use
Figures suggest that millions of adults in the UK have used these injections in the last 12 months, with desire continuing to grow.
- Use is greater among women than males.
- The middle-aged age group shows the greatest usage rates.
- A large proportion access the medications through private prescriptions rather than public health services.
In conclusion, researchers stress that while these medications are potent tools for shedding pounds, they are not a permanent cure and lasting health benefits hinges on combined lifestyle management.
