Fresh analysis suggests that people who discontinue popular GLP-1 drugs like semaglutide or tirzepatide may regain lost weight much more quickly than those who halt conventional diet and exercise regimens.
Research printed in a prominent medical journal demonstrates that while overweight people often shed substantial amounts of their total mass while using the jabs, the weight comes back at an average rate of nearly a kilo each month upon discontinuation.
"Users using these medications must be informed of the risk of fast weight regain when the treatment ends," warns lead investigator Dr. Susan Jebb.
That rate of regain suggests a return to starting mass within about a year and a half.
Analyzing Treatments
The research, which examined dozens of studies involving thousands of participants, contrasted the outcomes of the injectable medications with conventional dieting.
The team emphasize that individuals who lose weight through dieting usually have a more gradual weight regain—approximately 0.1 kg a month—post-intervention.
Understanding the Quick Regain
Experts propose the mechanism of the jabs accounts for the heightened weight return.
The injections imitate a natural hormone called GLP-1, which controls feelings of fullness.
"Long-term administration of the hormone 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 diminish sensitivity to its effects," said Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this hormone supplement leads to appetite is unsuppressed, making overeating far more likely."
A Chronic Issue?
Medical guidelines recommend the jabs for people with weight-linked health risks, accompanied by prescribed lifestyle changes.
Professionals contend that, due to the high risk of weight regain, the therapy might need to be long-term.
This view is echoed by drug manufacturers, who say that the findings "highlight the persistent character of obesity," comparing it to managing diseases like hypertension.
Patient Testimonies
People who have discontinued the medication explain a intense return of hunger.
"It was like something that goes on and you become starving," described one woman.
This challenge is worsened if patients have not adopted lasting lifestyle or habit modifications during treatment.
Growing Use
Figures indicate that millions of people in the UK have tried these injections in the past year, with desire remaining high.
- Use is higher among women than males.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion access the drugs through private healthcare rather than public health services.
In conclusion, experts stress that while GLP-1 drugs are powerful agents for shedding pounds, they are not a magic cure and maintained weight loss hinges on integrated behavioural management.
