Patients Coming Off Weight-Loss Injections Regain Weight at a Quadrupled Rate Than Dieters

New research indicates that people who stop using new weight-loss injections like semaglutide or tirzepatide can put back on lost weight at a significantly accelerated pace than those who stop conventional lifestyle programs.

Research printed in a major medical journal demonstrates that while overweight individuals can lose substantial amounts of their total mass while undergoing treatment, the mass comes back at an average rate of nearly a kilo each month after stopping.

"People using these drugs should be cognizant of the danger of fast weight regain when the medication ends," stated lead investigator Dr. Susan Jebb.

That rate of regain means a return to starting weight in about 18 months.

Comparing Treatments

The analysis, which looked at dozens of studies involving thousands of participants, compared the effects of these new drugs with conventional dieting.

The team note that people who shed pounds through diet and exercise usually experience a more gradual weight regain—approximately 0.1 kg a month—post-intervention.

Explaining the Quick Regain

Experts propose the way of the jabs is key to understanding the heightened weight return.

GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which moderates hunger.

"Artificially providing GLP-1 levels far above than normal may cause the system to produce less of its own natural hormone, and could reduce sensitivity to its effects," explained Dr. Adam Collins, a dietetics expert.

"Stopping of this hormone supplement leads to appetite is unsuppressed, making binge eating far more likely."

An Ongoing Disease?

The NHS suggest the injections for individuals with obesity-related health risks, alongside prescribed lifestyle changes.

Many experts contend that, due to the significant potential of relapse, the treatment should be considered life-long.

This perspective is supported by drug manufacturers, who state that the findings "highlight the persistent character of excess weight," similar to managing diseases like hypertension.

User Accounts

People who have discontinued the jabs explain a powerful return of cravings.

"It felt as if something activating and you become starving," described one woman.

The struggle is compounded if patients have not developed lasting lifestyle or habit changes during treatment.

Significant Interest

Survey data indicate that a significant number of people in the UK have tried weight-loss jabs in the past year, with demand continuing to grow.

• Adoption is more common among women compared to males.
• The middle-aged age group shows the highest level of interest.
• Many access the medications through private healthcare rather than public health services.

Ultimately, experts emphasize that while these medications are effective tools for weight loss, they are not a permanent fix and maintained weight loss hinges on ongoing behavioural changes.
