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

New research suggests that people who come off popular slimming jabs like Mounjaro or Wegovy can put back on lost weight much more quickly than those who halt conventional lifestyle programs.

Published data in a leading medical journal shows that while overweight people often shed substantial amounts of their total mass while undergoing treatment, the mass returns at an estimated rate of 0.8 kg per month once they quit.

"People using such drugs should be cognizant of the potential of rapid rebound weight gain when the medication concludes," stated expert Dr. Susan Jebb.

Such speed of regain implies a reversion to original mass in about one and a half years.

Analyzing Approaches

The analysis, which examined 37 of studies involving thousands of patients, contrasted the effects of the injectable medications with older methods.

Researchers emphasize that individuals who lose weight through lifestyle changes alone usually see a slower weight regain—approximately 100 grams monthly—after stopping.

Explaining the Quick Regain

Doctors suggest the mode of action of the drugs is key to understanding the heightened weight return.

GLP-1 drugs mimic a natural hormone called GLP-1, which controls hunger.

"Sustained high doses of the hormone levels far above than the body's typical production might result in the system to produce less of its endogenous GLP-1, and may also diminish responsiveness to its effects," said Dr. Adam Collins, a dietetics researcher.

"Stopping of this medication results in hunger is uncontrolled, making excessive eating much more probable."

An Ongoing Condition?

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

A number of clinicians say that, due to the significant potential of weight regain, the therapy might need to be ongoing.

This perspective is supported by pharmaceutical companies, who note that the findings "emphasize the persistent nature of excess weight," comparing it to managing conditions like high blood pressure.

User Testimonies

Users who have stopped the medication describe a powerful return of hunger.

"I experienced something that goes on and I was suddenly extremely hungry," said an individual.

This challenge is worsened if individuals have not adopted permanent dietary or behavioural modifications during treatment.

Widespread Interest

Figures suggest that a significant number of people in the UK have tried weight-loss jabs in the last 12 months, with interest continuing to grow.

• Use is more common among females than men.
• The middle-aged demographic shows the greatest level of interest.
• Many access the drugs through private healthcare rather than public health services.

Finally, experts caution that while the jabs are powerful tools for shedding pounds, they are not a permanent solution and lasting health benefits likely depends on combined lifestyle support.
