Individuals Stopping Weight-Loss Medications Regain Pounds at a Quadrupled Rate Compared to Those on Conventional Diets

New research suggests that individuals who come off new slimming jabs like Wegovy and Mounjaro may regain shed pounds far faster than those who halt conventional diet and exercise regimens.

Findings released in a leading medical journal points out that while overweight people frequently drop a large proportion of their body weight while on the medication, the mass comes back at an estimated rate of nearly a kilo each month once they quit.

"People buying such treatments must be informed of the potential of rapid rebound weight gain when the medication is stopped," cautioned lead investigator Dr. Susan Jebb.

This pace of regain means a return to starting weight in about one and a half years.

Comparing Treatments

The study, which reviewed dozens of trials involving thousands of participants, compared the results of GLP-1 agonists with older methods.

The team emphasize that people who shed pounds through lifestyle changes alone generally have a slower creep back—perhaps 100 grams monthly—after stopping.

Explaining the Rapid Rebound

Nutrition scientists suggest the way of the injections accounts for the heightened regain.

The injections mimic a body's own chemical called GLP-1, which helps regulate feelings of fullness.

"Long-term administration of the hormone concentrations far above than the body's typical production could lead to the body to generate a reduced amount of its endogenous GLP-1, and could reduce sensitivity to its actions," noted Dr. Adam Collins, a dietetics specialist.

"Withdrawal of this GLP-1 'fix' means appetite is no longer kept in check, making binge eating far more likely."

An Ongoing Disease?

The NHS suggest the injections for people with weight-linked medical conditions, alongside prescribed lifestyle changes.

Professionals argue that, due to the significant potential of weight regain, the treatment should be considered long-term.

This view is echoed by drug manufacturers, who note that the findings "underscore the persistent character of obesity," similar to managing conditions like hypertension.

User Experiences

People who have discontinued the jabs explain a intense resurgence of cravings.

"It was like a trigger flipping and you become starving," said a patient.

The struggle is worsened if individuals have not established permanent dietary or behavioural changes during treatment.

Growing Use

Survey data suggest that millions of people in the UK have tried these injections in the past year, with desire remaining high.

• Use is greater among females compared to men.
• The middle-aged demographic shows the greatest level of interest.
• A large proportion access the medications through private prescriptions rather than public health services.

In conclusion, experts caution that while the jabs are potent tools for shedding pounds, they are not a magic solution and maintained weight loss relies on integrated behavioural management.
