New research reveals that individuals who discontinue blockbuster weight-loss injections like semaglutide or tirzepatide may regain lost weight much more quickly than those who stop traditional diet and exercise regimens.
Research printed in a leading health publication shows that while obese individuals often shed substantial amounts of their total mass while undergoing treatment, the weight is regained at an average rate of nearly a kilo each month after stopping.
"Users buying these medications must be informed of the potential of rapid weight regain when the therapy concludes," warns expert Dr. Susan Jebb.
Such speed of regain suggests a return to original weight within about one and a half years.
Weighing Treatments
The study, which examined 37 of trials involving thousands of participants, contrasted the effects of the injectable medications with older methods.
The team emphasize that individuals who lose weight through dieting typically see a less rapid creep back—perhaps 100 grams monthly—after stopping.
Explaining the Fast Rebound
Experts suggest the mechanism of the drugs accounts for the amplified weight return.
These medications imitate a natural hormone called glucagon-like peptide-1, which controls appetite.
"Artificially providing the hormone concentrations several times higher than normal may cause the system to produce less of its endogenous hormone, and may also diminish sensitivity to its actions," explained Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' leads to appetite is uncontrolled, making overeating far more likely."
A Chronic Disease?
The NHS advise the injections for people with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
Many experts contend that, considering the likelihood of weight regain, the therapy should be considered long-term.
This opinion is echoed by drug manufacturers, who state that the findings "underscore the chronic nature of obesity," comparing it to managing diseases like hypertension.
Patient Testimonies
Individuals who have come off the medication describe a powerful return of cravings.
"I experienced a trigger activating and you're instantly ravenous," described one woman.
This difficulty is compounded if individuals have not developed sustainable lifestyle or habit changes during therapy.
Growing Interest
Survey data show that a significant number of people in the UK have used weight-loss jabs in the past year, with demand being substantial.
- Use is higher among females than males.
- The middle-aged demographic shows the highest level of interest.
- Many obtain the medications through private prescriptions rather than public health services.
In conclusion, clinicians stress that while these medications are potent tools for weight loss, they are not a permanent solution and maintained weight loss hinges on ongoing lifestyle changes.
