Fresh analysis reveals that people who discontinue new weight-loss injections like semaglutide or tirzepatide tend to recover lost weight far faster than those who end traditional lifestyle programs.
Published data in a prominent health publication shows that while obese individuals frequently drop a large proportion of their total mass while using the jabs, the weight is regained at an average rate of nearly a kilo each month once they quit.
"Individuals buying such treatments should be aware of the risk of quick weight regain when the treatment is stopped," stated lead investigator Dr. Susan Jebb.
This pace of recovery suggests a return to original mass in about 18 months.
Analyzing Therapies
The study, which examined dozens of trials involving over 9,000 of participants, compared the outcomes of these new drugs with older methods.
The team point out that people who lose weight through lifestyle changes alone generally have a more gradual creep back—perhaps 100 grams monthly—after stopping.
Understanding the Fast Regain
Experts propose the way of the jabs is key to understanding the accelerated weight return.
The injections copy a natural hormone called GLP-1, which controls appetite.
"Long-term administration of GLP-1 levels far above than the body's typical production might result in the body to generate a reduced amount of its own natural hormone, and may also lessen responsiveness to its actions," said Dr. Adam Collins, a nutrition expert.
"Withdrawal of this GLP-1 'fix' means hunger is no longer kept in check, making binge eating a significant risk."
An Ongoing Condition?
Health authorities recommend the jabs for people with weight-linked medical conditions, alongside recommended lifestyle changes.
Professionals say that, due to the high risk of relapse, the treatment might need to be ongoing.
This perspective is reinforced by pharmaceutical companies, who note that the findings "highlight the long-term nature of excess weight," similar to managing diseases like hypertension.
User Experiences
Users who have discontinued the medication report a powerful return of appetite.
"It felt as if a switch activating and I was suddenly starving," recalled an individual.
This difficulty is exacerbated if users have not adopted sustainable dietary or behavioural changes during treatment.
Widespread Use
Figures indicate that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with interest remaining high.
- Use is greater among women compared to men.
- The middle-aged age group shows the highest usage rates.
- Many access the medications through private healthcare rather than public health services.
Ultimately, experts caution that while these medications are effective tools for shedding pounds, they are not a magic solution and lasting health benefits relies on ongoing behavioural support.
