New research indicates that individuals who come off new weight-loss injections like semaglutide or tirzepatide may regain shed pounds far faster than those who stop conventional lifestyle programs.
Published data in a leading health publication points out that while obese individuals frequently drop about a fifth of their body weight while using the jabs, the mass is regained at an estimated rate of 0.8 kg per month once they quit.
"People buying these drugs must be cognizant of the potential of fast weight regain when the therapy is stopped," stated lead investigator Dr. Susan Jebb.
Such speed of recovery means a reversion to original weight in about one and a half years.
Analyzing Treatments
The analysis, which examined dozens of trials involving thousands of patients, contrasted the results of GLP-1 agonists with conventional dieting.
The team point out that people who shed pounds through lifestyle changes alone generally experience a slower creep back—approximately 100 grams monthly—post-intervention.
Explaining the Rapid Regain
Nutrition scientists propose the way of the injections accounts for the accelerated regain.
The injections copy a natural hormone called glucagon-like peptide-1, which controls feelings of fullness.
"Artificially providing GLP-1 concentrations far above than normal may cause the body to produce less of its own natural GLP-1, and could lessen sensitivity to its actions," noted Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this hormone supplement means hunger is unsuppressed, making excessive eating a significant risk."
An Ongoing Disease?
Health authorities suggest the injections for people with obesity-related health risks, alongside prescribed diet and exercise modifications.
Many experts argue that, considering the significant potential of weight regain, the therapy might need to be ongoing.
This view is echoed by drug manufacturers, who note that the results "emphasize the chronic nature of obesity," comparing it to managing diseases like hypertension.
Patient Experiences
Individuals who have come off the medication explain a intense return of appetite.
"I experienced a trigger flipping and you're instantly extremely hungry," described one woman.
This challenge is exacerbated if individuals have not established lasting dietary or behavioural modifications during treatment.
Significant Use
Recent estimates indicate that a significant number of adults in the UK have used weight-loss jabs in the past year, with demand continuing to grow.
- Adoption is higher among women than males.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion access the drugs through private healthcare rather than public health services.
Finally, experts emphasize that while these medications are potent tools for shedding pounds, they are not a magic cure and maintained weight loss likely depends on combined behavioural changes.
