Users Discontinuing Slimming Injections Put On Weight Far More Rapidly Compared to People Using Diet and Exercise

New research indicates that individuals who stop using popular weight-loss injections like Mounjaro or Wegovy can put back on lost weight much more quickly than those who stop traditional diet and exercise regimens.

Research printed in a prominent health publication shows that while overweight people can lose substantial amounts of their total mass while using the jabs, the weight returns at an average rate of 0.8 kg per month upon discontinuation.

"People buying these drugs need to be aware of the danger of rapid weight regain when the medication ends," warns researcher Dr. Susan Jebb.

This pace of recovery implies a return to starting weight within about a year and a half.

Weighing Therapies

The analysis, which examined 37 of studies involving over 9,000 of patients, contrasted the results of these new drugs with older methods.

The team emphasize that individuals who shed pounds through diet and exercise typically have a more gradual creep back—around 100 grams monthly—post-intervention.

Understanding the Fast Regain

Nutrition scientists propose the mechanism of the jabs explains the accelerated rebound.

The injections mimic a body's own chemical called glucagon-like peptide-1, which moderates feelings of fullness.

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

"Withdrawal of this medication leads to hunger is uncontrolled, making binge eating a significant risk."

An Ongoing Condition?

Medical guidelines suggest the injections for individuals with weight-linked medical conditions, accompanied by recommended lifestyle changes.

A number of clinicians say that, due to the high risk of weight regain, the treatment should be considered ongoing.

This view is echoed by drug manufacturers, who state that the findings "underscore the chronic character of excess weight," akin to managing conditions like diabetes.

Patient Testimonies

People who have come off the jabs explain a intense resurgence of hunger.

"It felt as if a switch flipping and I was suddenly extremely hungry," described a patient.

This challenge is worsened if users have not developed sustainable lifestyle or habit changes during treatment.

Widespread Interest

Figures indicate that millions of people in the UK have used these injections in the past year, with interest remaining high.

• Use is greater among females than men.
• The middle-aged age group shows the highest level of interest.
• Many access the drugs through private prescriptions rather than the NHS.

Finally, clinicians caution that while GLP-1 drugs are effective agents for shedding pounds, they are not a permanent solution and long-term success relies on combined lifestyle changes.
