Users Discontinuing Anti-Obesity Injections Put On Weight Far More Rapidly Than People Using Diet and Exercise

A recent study indicates that people who discontinue popular slimming jabs like Wegovy and Mounjaro can put back on reduced body mass far faster than those who stop traditional lifestyle regimens.

Research printed in a prominent medical journal demonstrates that while obese individuals can lose substantial amounts of their total mass while undergoing treatment, the weight comes back at an estimated rate of 0.8 kg per month once they quit.

"Users using such treatments need to be cognizant of the danger of fast rebound weight gain when the treatment is stopped," stated researcher Dr. Susan Jebb.

That rate of regain suggests a return to pre-treatment weight in about a year and a half.

Weighing Treatments

The research, which reviewed dozens of studies involving thousands of patients, contrasted the outcomes of GLP-1 agonists with older methods.

The team note that people who shed pounds through diet and exercise usually experience a less rapid weight regain—perhaps 100 grams monthly—once they finish.

Explaining the Fast Regain

Nutrition scientists believe the mode of action of the jabs explains the accelerated weight return.

GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.

"Long-term administration of GLP-1 concentrations far above than the body's typical production might result in the system to generate a reduced amount of its endogenous hormone, and could reduce responsiveness to its actions," said Dr. Adam Collins, a dietetics researcher.

"Stopping of this hormone supplement results in hunger is no longer kept in check, making binge eating a significant risk."

A Lifelong Issue?

The NHS recommend the injections for individuals with obesity-related medical conditions, alongside prescribed lifestyle changes.

Many experts contend that, given the significant potential of relapse, the treatment is often life-long.

This perspective is echoed by pharmaceutical companies, who state that the findings "emphasize the long-term nature of excess weight," akin to managing conditions like diabetes.

Patient Testimonies

Users who have discontinued the medication report a intense resurgence of appetite.

"I experienced a switch activating and you become ravenous," recalled a patient.

This challenge is worsened if users have not developed sustainable dietary or behavioural changes during treatment.

Growing Interest

Figures indicate that millions of adults in the UK have used these injections in the past year, with interest being substantial.

• Use is greater among women compared to men.
• The middle-aged demographic shows the greatest usage rates.
• A large proportion access the drugs through private prescriptions rather than the NHS.

Ultimately, clinicians caution that while the jabs are powerful agents for shedding pounds, they are not a permanent cure and maintained weight loss hinges on integrated lifestyle management.
