A recent study suggests that individuals who come off popular weight-loss injections like semaglutide or tirzepatide can put back on reduced body mass far faster than those who end traditional diet and exercise regimens.
Findings released in a major medical journal demonstrates that while obese individuals can lose a large proportion of their body weight while undergoing treatment, the mass comes back at an average rate of 0.8 kg per month after stopping.
"Individuals using these drugs must be informed of the potential of rapid rebound weight gain when the medication is stopped," stated researcher Dr. Susan Jebb.
That rate of recovery implies a return to original mass within about a year and a half.
Weighing Therapies
The analysis, which examined dozens of trials involving over 9,000 of patients, compared the outcomes of these new drugs with older methods.
Scientists emphasize that people who shed pounds through lifestyle changes alone typically experience a more gradual weight regain—around 100 grams monthly—once they finish.
Understanding the Quick Regain
Experts believe the mechanism of the drugs explains the amplified rebound.
These medications imitate a natural hormone called glucagon-like peptide-1, which helps regulate hunger.
"Sustained high doses of GLP-1 concentrations several times higher than normal could lead to the body to produce less of its endogenous hormone, and could lessen sensitivity to its actions," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this hormone supplement results in hunger is uncontrolled, making overeating a significant risk."
An Ongoing Disease?
Medical guidelines suggest the injections for people with obesity-related health risks, accompanied by prescribed lifestyle changes.
Professionals contend that, considering the significant potential of relapse, the treatment might need to be ongoing.
This perspective is echoed by drug manufacturers, who state that the findings "underscore the chronic character of excess weight," similar to managing diseases like high blood pressure.
Patient Testimonies
Users who have come off the medication report a sudden resurgence of hunger.
"It felt as if something flipping and you're instantly starving," recalled one woman.
This difficulty is compounded if users have not developed lasting lifestyle or habit changes during therapy.
Significant Use
Figures show that a significant number of people in the UK have used these injections in the last 12 months, with demand continuing to grow.
- Adoption is more common among women compared to men.
- The middle-aged demographic shows the greatest level of interest.
- Many obtain the medications through private prescriptions rather than the NHS.
Finally, clinicians caution that while these medications are effective tools for weight loss, they are not a permanent cure and lasting health benefits hinges on ongoing behavioural changes.
