A recent study reveals that people who stop using new GLP-1 drugs like semaglutide or tirzepatide may regain reduced body mass much more quickly than those who end conventional lifestyle regimens.
Research printed in a major medical journal shows that while obese people often shed about a fifth of their total mass while using the jabs, the weight comes back at an average rate of nearly a kilo each month after stopping.
"Individuals using such medications need to be cognizant of the danger of rapid weight regain when the treatment concludes," stated lead investigator Dr. Susan Jebb.
Such speed of recovery suggests a return to pre-treatment mass in about 18 months.
Comparing Approaches
The analysis, which examined 37 of trials involving thousands of participants, contrasted the outcomes of these new drugs with other pills.
Researchers note that people who shed pounds through diet and exercise typically have a less rapid weight regain—around 100 grams monthly—post-intervention.
The Reason for the Fast Rebound
Nutrition scientists suggest the way of the jabs explains the amplified weight return.
These medications imitate a natural hormone called glucagon-like peptide-1, which moderates appetite.
"Artificially providing the hormone levels several times higher than normal may cause the system to produce less of its own natural hormone, and could diminish responsiveness to its actions," said Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this GLP-1 'fix' means hunger is unsuppressed, making excessive eating much more probable."
A Lifelong Issue?
Health authorities recommend the injections for individuals with weight-linked health risks, accompanied by recommended lifestyle changes.
Many experts argue that, considering the significant potential of weight regain, the therapy should be considered long-term.
This opinion is echoed by drug manufacturers, who say that the findings "underscore the long-term character of excess weight," comparing it to managing conditions like hypertension.
User Accounts
Users who have come off the medication report a intense resurgence of cravings.
"I experienced something flipping and I was suddenly starving," said one woman.
This challenge is compounded if patients have not established permanent lifestyle or habit changes during treatment.
Widespread Interest
Recent estimates show that millions of adults in the UK have tried these injections in the last 12 months, with interest remaining high.
- Adoption is greater among females compared to males.
- The middle-aged demographic shows the highest usage rates.
- Many obtain the drugs through private prescriptions rather than the NHS.
Ultimately, experts stress that while GLP-1 drugs are effective agents for shedding pounds, they are not a standalone solution and maintained weight loss hinges on combined lifestyle support.
