Fresh analysis reveals that patients who stop using new slimming jabs like semaglutide or tirzepatide can put back on reduced body mass much more quickly than those who stop conventional diet and exercise programs.
Research printed in a prominent medical journal shows that while overweight people frequently drop a large proportion of their body weight while using the jabs, the weight returns at an estimated rate of 0.8 kg per month after stopping.
"Individuals using such medications should be informed of the danger of fast weight regain when the treatment is stopped," cautioned researcher Dr. Susan Jebb.
That rate of regain implies a return to pre-treatment mass within about 18 months.
Comparing Therapies
The research, which reviewed dozens of studies involving thousands of participants, contrasted the results of GLP-1 agonists with older methods.
Scientists emphasize that individuals who lose weight through diet and exercise typically experience a less rapid creep back—approximately 0.1 kg a month—once they finish.
Understanding the Quick Regain
Experts propose the way of the jabs explains the amplified weight return.
These medications copy a natural hormone called GLP-1, which moderates hunger.
"Sustained high doses of the hormone levels several times higher than normal could lead to the body to produce less of its own natural hormone, and may also diminish sensitivity to its effects," said Dr. Adam Collins, a nutrition specialist.
"Stopping of this GLP-1 'fix' leads to hunger is unsuppressed, making binge eating far more likely."
A Chronic Issue?
The NHS recommend the injections for individuals with weight-linked health risks, alongside prescribed diet and exercise modifications.
A number of clinicians argue that, due to the significant potential of weight regain, the treatment might need to be long-term.
This view is echoed by pharmaceutical companies, who say that the results "highlight the long-term nature of excess weight," comparing it to managing conditions like diabetes.
User Experiences
Users who have come off the medication report a powerful resurgence of cravings.
"I experienced something activating and you're instantly extremely hungry," recalled a patient.
The struggle is worsened if individuals have not established permanent lifestyle or habit changes during therapy.
Growing Adoption
Survey data indicate that a significant number of people in the UK have used these injections in the past year, with interest remaining high.
- Adoption is higher among women compared to males.
- The middle-aged demographic shows the greatest level of interest.
- Many access the drugs through private prescriptions rather than the NHS.
In conclusion, experts stress that while GLP-1 drugs are powerful agents for shedding pounds, they are not a permanent fix and maintained weight loss hinges on combined behavioural management.
