Patients Coming Off Slimming Injections Regain Weight Far More Rapidly Than Those on Conventional Diets

New research indicates that people who come off new GLP-1 drugs like Mounjaro or Wegovy tend to recover reduced body mass at a significantly accelerated pace than those who halt traditional diet and exercise plans.

Research printed in a prominent medical journal points out that while overweight people can lose substantial amounts of their body weight while using the jabs, the mass is regained at an estimated rate of 0.8 kg per month after stopping.

"Users using such treatments need to be aware of the danger of rapid weight regain when the medication is stopped," cautioned expert Dr. Susan Jebb.

This pace of regain implies a reversion to original weight in about a year and a half.

Weighing Approaches

The analysis, which reviewed 37 of trials involving thousands of participants, contrasted the outcomes of the injectable medications with other pills.

Researchers note that individuals who shed pounds through diet and exercise usually have a slower weight regain—approximately 100 grams monthly—after stopping.

Explaining the Rapid Rebound

Nutrition scientists propose the mode of action of the injections accounts for the accelerated regain.

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

"Long-term administration of GLP-1 concentrations several times higher than normal may cause the body to generate a reduced amount of its endogenous hormone, and may also lessen responsiveness to its actions," explained Dr. Adam Collins, a nutrition researcher.

"Stopping of this hormone supplement leads to appetite is no longer kept in check, making binge eating far more likely."

A Chronic Condition?

Medical guidelines recommend the jabs for individuals with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.

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

This view is reinforced by pharmaceutical companies, who say that the findings "highlight the long-term nature of excess weight," akin to managing diseases like diabetes.

User Testimonies

Users who have come off the jabs report a intense return of cravings.

"It felt as if something activating and you become ravenous," recalled a patient.

This difficulty is exacerbated if users have not adopted lasting dietary or behavioural modifications during treatment.

Significant Use

Recent estimates indicate that millions of adults in the UK have tried these injections in the past year, with demand remaining high.

• Adoption is more common among women compared to men.
• The middle-aged demographic shows the greatest level of interest.
• A large proportion obtain the medications through private healthcare rather than public health services.

Finally, clinicians caution that while these medications are potent tools for weight loss, they are not a standalone solution and maintained weight loss likely depends on combined behavioural management.
