Patients Stopping Anti-Obesity Injections Gain Back Pounds Four Times Faster Compared to Dieters

New research indicates that people who discontinue new GLP-1 drugs like semaglutide or tirzepatide can put back on shed pounds much more quickly than those who stop traditional lifestyle regimens.

Findings released in a leading medical journal demonstrates that while overweight individuals can lose a large proportion of their body weight while on the medication, the weight returns at an estimated rate of nearly a kilo each month upon discontinuation.

"Individuals buying these treatments need to be informed of the risk of fast weight regain when the treatment concludes," warns lead investigator Dr. Susan Jebb.

That rate of regain means a return to original weight in about one and a half years.

Analyzing Therapies

The research, which examined dozens of trials involving over 9,000 of patients, contrasted the results of these new drugs with other pills.

Scientists emphasize that people who shed pounds through lifestyle changes alone generally see a less rapid weight regain—perhaps 0.1 kg a month—once they finish.

The Reason for the Quick Rebound

Experts believe the mode of action of the jabs explains the accelerated weight return.

The injections copy a body's own chemical called GLP-1, which moderates hunger.

"Long-term administration of the hormone levels several times higher than normal may cause the system to produce less of its endogenous hormone, and may also diminish sensitivity to its actions," noted Dr. Adam Collins, a nutrition specialist.

"Stopping of this medication leads to hunger is unsuppressed, making binge eating much more probable."

A Lifelong Condition?

Medical guidelines recommend the jabs for people with obesity-related health risks, alongside recommended lifestyle changes.

Professionals argue that, due to the high risk of relapse, the therapy is often life-long.

This opinion is supported by drug manufacturers, who say that the results "underscore the persistent character of obesity," similar to managing conditions like high blood pressure.

Patient Testimonies

Individuals who have discontinued the jabs explain a intense return of appetite.

"It felt as if a trigger flipping and you're instantly starving," said an individual.

This difficulty is worsened if patients have not established lasting dietary or behavioural changes during therapy.

Significant Adoption

Recent estimates suggest that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with interest remaining high.

• Use is more common among women compared to men.
• The 40s and 50s age group shows the greatest usage rates.
• Many access the drugs through private prescriptions rather than the NHS.

Ultimately, clinicians emphasize that while the jabs are potent agents for shedding pounds, they are not a standalone cure and maintained weight loss likely depends on integrated behavioural changes.
