Individuals Discontinuing Anti-Obesity Injections Put On Pounds at a Quadrupled Rate Than Dieters

New research indicates that individuals who come off blockbuster GLP-1 drugs like Wegovy and Mounjaro can put back on shed pounds much more quickly than those who halt conventional diet and exercise regimens.

Published data in a leading medical journal shows that while obese individuals frequently drop a large proportion of their total mass while on the medication, the weight returns at an estimated rate of 0.8 kg per month upon discontinuation.

"Users using these treatments need to be aware of the risk of rapid weight regain when the treatment is stopped," stated lead investigator Dr. Susan Jebb.

This pace of regain implies a return to pre-treatment weight in about 18 months.

Comparing Therapies

The research, which looked at dozens of trials involving over 9,000 of participants, contrasted the results of the injectable medications with older methods.

The team note that people who lose weight through dieting usually see a less rapid weight regain—perhaps 100 grams monthly—once they finish.

The Reason for the Rapid Rebound

Doctors believe the mode of action of the injections explains the amplified rebound.

The injections mimic a natural hormone called GLP-1, which controls feelings of fullness.

"Artificially providing the hormone concentrations several times higher than the body's typical production may cause the body to produce less of its endogenous hormone, and may also diminish responsiveness to its effects," noted Dr. Adam Collins, a nutrition expert.

"Discontinuation of this hormone supplement means hunger is uncontrolled, making overeating far more likely."

An Ongoing Issue?

Medical guidelines suggest the jabs for individuals with obesity-related medical conditions, alongside recommended lifestyle changes.

A number of clinicians argue that, due to the significant potential of relapse, the therapy might need to be long-term.

This opinion is supported by pharmaceutical companies, who note that the results "emphasize the chronic nature of excess weight," akin to managing diseases like diabetes.

User Testimonies

People who have discontinued the jabs describe a sudden return of cravings.

"It was like a trigger flipping and I was suddenly starving," described a patient.

This challenge is worsened if individuals have not developed permanent lifestyle or habit modifications during treatment.

Growing Adoption

Recent estimates show that millions of people in the UK have used these injections in the past year, with demand continuing to grow.

• Use is higher among females compared to males.
• The middle-aged age group shows the greatest level of interest.
• Many obtain the drugs through private prescriptions rather than public health services.

Finally, clinicians caution that while these medications are potent agents for shedding pounds, they are not a standalone fix and lasting health benefits likely depends on integrated lifestyle support.
