Patients Stopping Anti-Obesity Injections Put On Weight Far More Rapidly Than Those on Conventional Diets

New research reveals that individuals who stop using new GLP-1 drugs like semaglutide or tirzepatide tend to recover lost weight much more quickly than those who end traditional diet and exercise plans.

Published data in a leading medical journal points out that while overweight people often shed substantial amounts of their body weight while on the medication, the weight returns at an average rate of nearly a kilo each month upon discontinuation.

"Individuals buying such medications need to be cognizant of the danger of fast rebound weight gain when the therapy concludes," cautioned researcher Dr. Susan Jebb.

That rate of recovery implies a reversion to original mass within about a year and a half.

Comparing Therapies

The analysis, which examined dozens of studies involving thousands of patients, contrasted the results of these new drugs with other pills.

The team emphasize that individuals who shed pounds through dieting typically see a more gradual creep back—approximately 0.1 kg a month—post-intervention.

The Reason for the Quick Regain

Nutrition scientists suggest the mode of action of the jabs accounts for the accelerated weight return.

The injections mimic a natural hormone called GLP-1, which helps regulate hunger.

"Sustained high doses of the hormone concentrations far above than the body's typical production might result in the body to produce less of its endogenous hormone, and may also lessen sensitivity to its effects," noted Dr. Adam Collins, a dietetics expert.

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

A Chronic Condition?

Health authorities advise the jabs for people with weight-linked health risks, alongside recommended lifestyle changes.

A number of clinicians contend that, given the likelihood of relapse, the therapy is often long-term.

This view is reinforced by pharmaceutical companies, who note that the results "underscore the persistent character of excess weight," comparing it to managing diseases like diabetes.

User Testimonies

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

"It felt as if something flipping and you become extremely hungry," said a patient.

This challenge is compounded if patients have not adopted permanent lifestyle or habit changes during therapy.

Growing Interest

Figures show that millions of adults in the UK have used these injections in the past year, with desire continuing to grow.

• Use is more common among females than 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, researchers emphasize that while the jabs are potent tools for weight loss, they are not a standalone solution and long-term success likely depends on integrated lifestyle support.
