Users Stopping Slimming Injections Gain Back Weight Far More Rapidly Compared to Dieters

New research reveals that individuals who come off blockbuster weight-loss injections like Mounjaro or Wegovy can put back on reduced body mass at a significantly accelerated pace than those who end traditional diet and exercise regimens.

Research printed in a leading medical journal demonstrates that while overweight people frequently drop substantial amounts of their body weight while using the jabs, the weight is regained at an average rate of nearly a kilo each month upon discontinuation.

"Users purchasing these treatments must be cognizant of the risk of rapid weight regain when the treatment concludes," stated lead investigator Dr. Susan Jebb.

This pace of recovery suggests a return to original mass within about a year and a half.

Analyzing Treatments

The analysis, which looked at dozens of studies involving thousands of participants, contrasted the results of the injectable medications with other pills.

The team note that people who lose weight through diet and exercise typically experience a less rapid weight regain—approximately 100 grams monthly—once they finish.

Understanding the Fast Rebound

Doctors propose the mode of action of the drugs explains the heightened weight return.

These medications mimic a body's own chemical called GLP-1, which helps regulate appetite.

"Artificially providing GLP-1 levels several times higher than normal may cause the body to produce less of its own natural GLP-1, and may also diminish sensitivity to its actions," explained Dr. Adam Collins, a dietetics expert.

"Stopping of this medication leads to hunger is no longer kept in check, making overeating much more probable."

A Chronic Disease?

The NHS advise the injections for people with weight-linked health risks, alongside recommended lifestyle changes.

A number of clinicians contend that, considering the likelihood of weight regain, the treatment should be considered ongoing.

This view is supported by pharmaceutical companies, who say that the results "underscore the chronic nature of excess weight," akin to managing conditions like high blood pressure.

Patient Accounts

People who have discontinued the jabs report a intense resurgence of appetite.

"I experienced a switch that goes on and I was suddenly ravenous," said one woman.

The struggle is compounded if individuals have not adopted sustainable lifestyle or habit modifications during therapy.

Growing Interest

Recent estimates suggest that millions of adults in the UK have used weight-loss jabs in the past year, with demand being substantial.

• Adoption is higher among women compared to males.
• The 40s and 50s demographic shows the greatest usage rates.
• A large proportion obtain the drugs through private prescriptions rather than the NHS.

Ultimately, researchers stress that while GLP-1 drugs are effective agents for shedding pounds, they are not a magic fix and long-term success likely depends on integrated lifestyle support.
