Fresh analysis reveals that individuals who come off new weight-loss injections like semaglutide or tirzepatide may regain lost weight at a significantly accelerated pace than those who stop traditional diet and exercise plans.
Published data in a prominent health publication points out that while overweight individuals frequently drop a large proportion of their total mass while undergoing treatment, the weight is regained at an average rate of nearly a kilo each month once they quit.
"Users purchasing such drugs should be cognizant of the danger of fast rebound weight gain when the treatment ends," stated lead investigator Dr. Susan Jebb.
Such speed of regain implies a return to pre-treatment mass within about 18 months.
Analyzing Treatments
The analysis, which examined dozens of trials involving thousands of participants, contrasted the results of the injectable medications with other pills.
Scientists emphasize that people who shed pounds through diet and exercise typically experience a more gradual weight regain—around 0.1 kg a month—after stopping.
The Reason for the Quick Rebound
Nutrition scientists believe the way of the jabs accounts for the accelerated rebound.
GLP-1 drugs mimic a natural hormone called glucagon-like peptide-1, which helps regulate hunger.
"Long-term administration of GLP-1 concentrations far above than normal might result in 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 expert.
"Withdrawal of this GLP-1 'fix' means appetite is uncontrolled, making excessive eating a significant risk."
A Chronic Disease?
Medical guidelines advise the injections for people with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
Professionals contend that, given the high risk of relapse, the treatment is often long-term.
This view is supported by drug manufacturers, who say that the findings "underscore the long-term nature of obesity," akin to managing conditions like diabetes.
Patient Testimonies
People who have come off the jabs describe a powerful return of hunger.
"It felt as if something that goes on and you become ravenous," said one woman.
This difficulty is exacerbated if users have not established permanent dietary or behavioural modifications during therapy.
Significant Interest
Recent estimates show that a significant number of adults in the UK have tried these injections in the past year, with demand continuing to grow.
- Use is higher among females than males.
- The middle-aged demographic shows the greatest usage rates.
- Many obtain the drugs through private prescriptions rather than the NHS.
Ultimately, clinicians emphasize that while these medications are potent agents for weight loss, they are not a permanent cure and lasting health benefits hinges on combined behavioural management.
