Patients Discontinuing Slimming Injections Gain Back Weight Four Times Faster Than People Using Diet and Exercise

A recent study reveals that individuals who discontinue blockbuster GLP-1 drugs like Mounjaro or Wegovy may regain lost weight at a significantly accelerated pace than those who end traditional lifestyle plans.

Findings released in a leading medical journal shows that while obese individuals can lose a large proportion of their total mass while on the medication, the weight is regained at an average rate of 0.8 kg per month once they quit.

"Users using such drugs should be cognizant of the potential of quick rebound weight gain when the treatment ends," stated researcher Dr. Susan Jebb.

This pace of recovery means a return to original weight within about one and a half years.

Comparing Therapies

The research, which examined 37 of trials involving over 9,000 of patients, compared the results of the injectable medications with older methods.

The team note that people who lose weight through dieting generally experience a more gradual creep back—perhaps 100 grams monthly—after stopping.

Explaining the Fast Regain

Nutrition scientists believe the mode of action of the injections is key to understanding the amplified rebound.

GLP-1 drugs copy a natural hormone called GLP-1, which moderates appetite.

"Sustained high doses of the hormone concentrations several times higher than normal might result in the body to produce less of its endogenous hormone, and may also lessen responsiveness to its actions," noted Dr. Adam Collins, a nutrition specialist.

"Withdrawal of this hormone supplement means appetite is unsuppressed, making binge eating much more probable."

A Chronic Condition?

Health authorities suggest the injections for people with weight-linked medical conditions, accompanied by prescribed lifestyle changes.

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

This opinion is reinforced by pharmaceutical companies, who state that the results "underscore the chronic nature of obesity," comparing it to managing diseases like high blood pressure.

Patient Testimonies

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

"It was like something flipping and I was suddenly extremely hungry," recalled an individual.

This challenge is compounded if individuals have not adopted sustainable dietary or behavioural changes during therapy.

Widespread Interest

Figures indicate that a significant number of people in the UK have used these injections in the last 12 months, with interest remaining high.

• Use is more common among women than males.
• The 40s and 50s demographic shows the greatest usage rates.
• Many obtain the drugs through private prescriptions rather than the NHS.

Ultimately, clinicians emphasize that while these medications are powerful agents for shedding pounds, they are not a magic fix and maintained weight loss likely depends on integrated lifestyle management.
