New research indicates that individuals who stop using blockbuster slimming jabs like Wegovy and Mounjaro tend to recover shed pounds far faster than those who stop conventional lifestyle regimens.
Published data in a leading health publication shows that while obese people can lose about a fifth of their total mass while undergoing treatment, the mass returns at an average rate of nearly a kilo each month once they quit.
"People buying these medications should be cognizant of the risk of rapid rebound weight gain when the treatment ends," cautioned lead investigator Dr. Susan Jebb.
This pace of regain suggests a reversion to original mass within about a year and a half.
Analyzing Treatments
The research, which examined dozens of trials involving over 9,000 of patients, contrasted the effects of the injectable medications with older methods.
The team note that people who shed pounds through lifestyle changes alone generally experience a less rapid weight regain—approximately 100 grams monthly—post-intervention.
The Reason for the Quick Rebound
Doctors propose the mechanism of the drugs explains the amplified weight return.
GLP-1 drugs mimic a natural hormone called glucagon-like peptide-1, which controls appetite.
"Long-term administration of the hormone concentrations far above than normal may cause the body to produce less of its own natural hormone, and may also lessen responsiveness to its effects," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this GLP-1 'fix' results in hunger is uncontrolled, making overeating far more likely."
A Lifelong Issue?
Health authorities suggest the injections for individuals with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
A number of clinicians say that, considering the high risk of relapse, the treatment is often long-term.
This perspective is reinforced by drug manufacturers, who say that the findings "highlight the persistent nature of excess weight," akin to managing diseases like hypertension.
Patient Accounts
People who have stopped the jabs describe a powerful resurgence of hunger.
"I experienced a switch flipping and you're instantly ravenous," recalled one woman.
This difficulty is worsened if individuals have not developed sustainable lifestyle or habit modifications during treatment.
Widespread Use
Recent estimates indicate that a significant number of adults in the UK have used these injections in the past year, with desire continuing to grow.
- Adoption is greater among females than men.
- The middle-aged age group shows the greatest level of interest.
- Many obtain the medications through private prescriptions rather than the NHS.
In conclusion, researchers stress that while the jabs are potent tools for weight loss, they are not a permanent solution and lasting health benefits relies on ongoing behavioural changes.
