Users Coming Off Slimming Medications Put On Pounds Far More Rapidly Than Dieters

New research suggests that individuals who stop using blockbuster weight-loss injections like Mounjaro or Wegovy may regain shed pounds much more quickly than those who end traditional diet and exercise plans.

Published data in a leading medical journal points out that while obese individuals can lose a large proportion of their body weight while on the medication, the weight comes back at an average rate of 0.8 kg per month upon discontinuation.

"Individuals purchasing these treatments must be aware of the danger of rapid weight regain when the therapy is stopped," stated researcher Dr. Susan Jebb.

This pace of regain suggests a return to pre-treatment weight within about 18 months.

Comparing Approaches

The study, which examined 37 of studies involving over 9,000 of patients, contrasted the outcomes of the injectable medications with other pills.

Researchers point out that individuals who shed pounds through lifestyle changes alone generally have a slower creep back—around 100 grams monthly—post-intervention.

Explaining the Quick Rebound

Doctors suggest the way of the drugs is key to understanding the accelerated weight return.

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

"Artificially providing GLP-1 levels far above than the body's typical production could lead to the body to generate a reduced amount of its own natural hormone, and may also diminish sensitivity to its effects," explained Dr. Adam Collins, a dietetics specialist.

"Withdrawal of this medication means appetite is uncontrolled, making binge eating far more likely."

An Ongoing Condition?

Medical guidelines suggest the jabs for individuals with obesity-related health risks, alongside recommended diet and exercise modifications.

Many experts say that, given the likelihood of relapse, the treatment should be considered long-term.

This opinion is echoed by pharmaceutical companies, who note that the findings "underscore the persistent character of excess weight," similar to managing conditions like diabetes.

Patient Accounts

People who have come off the jabs describe a powerful resurgence of cravings.

"It felt as if something that goes on and you're instantly extremely hungry," described one woman.

This difficulty is worsened if individuals have not established permanent dietary or behavioural changes during treatment.

Widespread Interest

Survey data suggest that a significant number of adults in the UK have used these injections in the last 12 months, with demand remaining high.

• Use is more common among women compared to men.
• The middle-aged age group shows the highest usage rates.
• A large proportion obtain the medications through private healthcare rather than public health services.

Ultimately, researchers stress that while the jabs are potent agents for shedding pounds, they are not a standalone fix and lasting health benefits relies on combined behavioural support.
