Users Coming Off Weight-Loss Injections Put On Weight Far More Rapidly Compared to Those on Conventional Diets

A recent study indicates that individuals who stop using new weight-loss injections like Wegovy and Mounjaro may regain shed pounds far faster than those who end traditional diet and exercise plans.

Published data in a major medical journal points out that while overweight people often shed about a fifth of their total mass while using the jabs, the mass comes back at an average rate of nearly a kilo each month upon discontinuation.

"Individuals purchasing these treatments should be informed of the potential of rapid weight regain when the treatment concludes," cautioned researcher Dr. Susan Jebb.

This pace of regain suggests a return to original mass in about 18 months.

Analyzing Treatments

The study, which looked at dozens of trials involving thousands of patients, contrasted the effects of these new drugs with conventional dieting.

The team note that people who lose weight through diet and exercise typically experience a less rapid creep back—perhaps 0.1 kg a month—once they finish.

Understanding the Rapid Rebound

Experts believe the mechanism of the injections is key to understanding the heightened rebound.

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

"Artificially providing the hormone levels far above than the body's typical production might result in the body to produce less of its endogenous GLP-1, and may also lessen responsiveness to its actions," explained Dr. Adam Collins, a nutrition researcher.

"Discontinuation of this medication means appetite is uncontrolled, making binge eating a significant risk."

An Ongoing Condition?

Medical guidelines recommend the injections for people with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.

Many experts say that, due to the likelihood of weight regain, the treatment is often ongoing.

This view is supported by pharmaceutical companies, who note that the results "highlight the chronic nature of excess weight," akin to managing diseases like hypertension.

User Experiences

Users who have stopped the medication report a powerful return of cravings.

"I experienced a switch that goes on and I was suddenly extremely hungry," said a patient.

The struggle is compounded if patients have not developed sustainable dietary or behavioural changes during therapy.

Significant Interest

Figures suggest that millions of people in the UK have used weight-loss jabs in the past year, with desire continuing to grow.

• Adoption is higher among women compared to males.
• The middle-aged age group shows the greatest usage rates.
• Many obtain the drugs through private prescriptions rather than public health services.

Ultimately, clinicians emphasize that while the jabs are powerful tools for shedding pounds, they are not a permanent solution and long-term success relies on ongoing lifestyle management.
