New research indicates that patients who discontinue blockbuster slimming jabs like Mounjaro or Wegovy tend to recover reduced body mass far faster than those who stop traditional lifestyle regimens.
Research printed in a major medical journal demonstrates that while obese individuals often shed about a fifth of their body weight while undergoing treatment, the mass is regained at an average rate of 0.8 kg per month once they quit.
"Users buying these treatments should be cognizant of the risk of rapid rebound weight gain when the medication ends," warns researcher Dr. Susan Jebb.
Such speed of regain means a reversion to pre-treatment weight in about one and a half years.
Analyzing Treatments
The research, which reviewed 37 of trials involving over 9,000 of participants, contrasted the outcomes of the injectable medications with conventional dieting.
The team note that individuals who lose weight through lifestyle changes alone typically experience a more gradual creep back—approximately 100 grams monthly—post-intervention.
Understanding the Quick Rebound
Experts believe the way of the drugs explains the amplified regain.
GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 levels several times higher than the body's typical production might result in the body to produce less of its own natural hormone, and could reduce sensitivity to its actions," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this medication means hunger is uncontrolled, making binge eating far more likely."
An Ongoing Condition?
The NHS recommend the jabs for individuals with obesity-related health risks, alongside prescribed diet and exercise modifications.
Professionals contend that, given the significant potential of relapse, the treatment might need to be life-long.
This view is supported by drug manufacturers, who say that the findings "highlight the persistent nature of obesity," comparing it to managing conditions like hypertension.
User Testimonies
Users who have come off the medication describe a intense return of cravings.
"I experienced a trigger that goes on and you become ravenous," recalled one woman.
This difficulty is worsened if patients have not developed lasting dietary or behavioural changes during therapy.
Widespread Use
Recent estimates show that a significant number of adults in the UK have tried these injections in the past year, with demand being substantial.
- Use is higher among women compared to males.
- The middle-aged demographic shows the greatest level of interest.
- Many access the medications through private healthcare rather than public health services.
Ultimately, researchers stress that while the jabs are effective tools for weight loss, they are not a permanent fix and lasting health benefits relies on combined lifestyle support.
