New research indicates that patients who come off new slimming jabs like Mounjaro or Wegovy tend to recover shed pounds at a significantly accelerated pace than those who stop traditional lifestyle plans.
Research printed in a prominent health publication shows that while obese individuals often shed substantial amounts of their body weight while undergoing treatment, the mass returns at an average rate of nearly a kilo each month upon discontinuation.
"People buying such medications should be cognizant of the potential of quick rebound weight gain when the medication concludes," stated researcher Dr. Susan Jebb.
Such speed of recovery implies a return to pre-treatment weight within about 18 months.
Weighing Therapies
The research, which reviewed dozens of studies involving thousands of patients, contrasted the outcomes of GLP-1 agonists with other pills.
Researchers note that people who shed pounds through diet and exercise typically experience a less rapid creep back—around 100 grams monthly—once they finish.
Understanding the Rapid Rebound
Nutrition scientists propose the mode of action of the drugs accounts for the heightened regain.
The injections copy a natural hormone called GLP-1, which controls feelings of fullness.
"Sustained high doses of the hormone levels far above than normal might result in the system to produce less of its endogenous GLP-1, and could lessen sensitivity to its effects," explained Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this hormone supplement leads to appetite is uncontrolled, making binge eating far more likely."
An Ongoing Condition?
Medical guidelines recommend the jabs for individuals with weight-linked medical conditions, alongside recommended diet and exercise modifications.
Many experts contend that, given the likelihood of weight regain, the treatment might need to be life-long.
This view is supported by drug manufacturers, who note that the results "highlight the persistent nature of obesity," similar to managing conditions like diabetes.
Patient Accounts
People who have discontinued the medication explain a intense resurgence of cravings.
"It felt as if a trigger flipping and you become ravenous," described a patient.
This challenge is compounded if patients have not established sustainable dietary or behavioural modifications during treatment.
Widespread Interest
Recent estimates suggest that millions of adults in the UK have used these injections in the past year, with desire remaining high.
- Use is more common among women compared to men.
- The middle-aged demographic shows the highest level of interest.
- A large proportion access the drugs through private healthcare rather than the NHS.
Ultimately, experts caution that while the jabs are powerful tools for weight loss, they are not a magic solution and long-term success hinges on integrated behavioural support.
