New research reveals that individuals who discontinue blockbuster slimming jabs like semaglutide or tirzepatide may regain reduced body mass much more quickly than those who stop traditional diet and exercise regimens.
Research printed in a major medical journal demonstrates that while overweight people can lose substantial amounts of their body weight while on the medication, the weight comes back at an estimated rate of nearly a kilo each month after stopping.
"Individuals purchasing these medications should be aware of the potential of quick weight regain when the treatment ends," warns lead investigator Dr. Susan Jebb.
This pace of regain suggests a reversion to starting mass in about a year and a half.
Analyzing Approaches
The study, which reviewed 37 of trials involving thousands of participants, compared the outcomes of these new drugs with conventional dieting.
Scientists note that individuals who lose weight through dieting generally see a less rapid creep back—perhaps 100 grams monthly—once they finish.
The Reason for the Quick Rebound
Nutrition scientists propose the way of the drugs is key to understanding the amplified regain.
These medications copy a natural hormone called glucagon-like peptide-1, which moderates appetite.
"Long-term administration of GLP-1 concentrations several times higher than the body's typical production may cause the system to generate a reduced amount of its own natural GLP-1, and could reduce responsiveness to its actions," said Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this medication leads to appetite is uncontrolled, making overeating far more likely."
A Lifelong Issue?
Health authorities suggest the injections for people with weight-linked health risks, alongside prescribed lifestyle changes.
Professionals argue that, given the high risk of weight regain, the treatment is often ongoing.
This opinion is echoed by drug manufacturers, who state that the results "emphasize the chronic nature of excess weight," similar to managing conditions like hypertension.
User Testimonies
Individuals who have stopped the jabs describe a powerful resurgence of cravings.
"I experienced a switch flipping and you become starving," said an individual.
This challenge is worsened if patients have not developed sustainable lifestyle or habit changes during treatment.
Growing Use
Recent estimates suggest that a significant number of people in the UK have used these injections in the past year, with desire being substantial.
- Adoption is higher among females than men.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
In conclusion, experts emphasize that while GLP-1 drugs are potent agents for shedding pounds, they are not a standalone fix and maintained weight loss relies on integrated lifestyle changes.
