A recent study indicates that individuals who discontinue new weight-loss injections like semaglutide or tirzepatide tend to recover reduced body mass at a significantly accelerated pace than those who halt traditional diet and exercise programs.
Published data in a major medical journal points out that while obese people often shed a large proportion of their body weight while on the medication, the mass returns at an average rate of nearly a kilo each month once they quit.
"People buying such treatments should be aware of the danger of rapid rebound weight gain when the therapy is stopped," warns lead investigator Dr. Susan Jebb.
This pace of recovery implies a reversion to starting mass in about one and a half years.
Weighing Therapies
The analysis, which looked at dozens of studies involving thousands of patients, compared the outcomes of the injectable medications with older methods.
The team emphasize that people who shed pounds through lifestyle changes alone generally experience a less rapid weight regain—around 100 grams monthly—after stopping.
The Reason for the Quick Rebound
Doctors propose the way of the drugs accounts for the accelerated weight return.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which controls appetite.
"Long-term administration of the hormone concentrations several times higher than normal might result in the system to produce less of its endogenous GLP-1, and may also lessen sensitivity to its effects," noted Dr. Adam Collins, a nutrition researcher.
"Stopping of this GLP-1 'fix' leads to appetite is uncontrolled, making excessive eating far more likely."
A Chronic Issue?
The NHS advise the injections for individuals with weight-linked medical conditions, alongside prescribed lifestyle changes.
Many experts contend that, considering the high risk of relapse, the treatment might need to be ongoing.
This opinion is supported by drug manufacturers, who say that the findings "emphasize the long-term character of obesity," akin to managing diseases like high blood pressure.
User Experiences
Individuals who have stopped the medication explain a sudden return of cravings.
"It was like a switch that goes on and you're instantly starving," recalled one woman.
This difficulty is worsened if users have not adopted lasting lifestyle or habit modifications during therapy.
Significant Adoption
Recent estimates show that a significant number of people in the UK have tried these injections in the past year, with interest remaining high.
- Use is higher among women compared to males.
- The 40s and 50s age group shows the greatest usage rates.
- Many obtain the medications through private prescriptions rather than public health services.
In conclusion, experts emphasize that while these medications are potent tools for weight loss, they are not a permanent fix and long-term success hinges on ongoing behavioural management.
