Fresh analysis indicates that people who discontinue blockbuster weight-loss injections like semaglutide or tirzepatide may regain shed pounds far faster than those who halt traditional lifestyle regimens.
Findings released in a prominent health publication points out that while obese people often shed about a fifth of their total mass while using the jabs, the mass comes back at an average rate of 0.8 kg per month upon discontinuation.
"Individuals buying such medications need to be cognizant of the potential of fast weight regain when the treatment is stopped," cautioned researcher Dr. Susan Jebb.
Such speed of recovery suggests a return to pre-treatment mass within about a year and a half.
Weighing Treatments
The analysis, which examined dozens of trials involving over 9,000 of participants, compared the effects of GLP-1 agonists with other pills.
Scientists note that people who lose weight through diet and exercise typically experience a slower weight regain—around 100 grams monthly—after stopping.
The Reason for the Fast Rebound
Experts believe the way of the drugs is key to understanding the heightened weight return.
The injections mimic a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 levels far above than normal may cause the body to generate a reduced amount of its own natural hormone, and may also diminish sensitivity to its effects," noted Dr. Adam Collins, a nutrition specialist.
"Stopping of this medication leads to hunger is unsuppressed, making excessive eating far more likely."
A Chronic Disease?
Health authorities recommend the jabs for people with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
Professionals contend that, due to the likelihood of weight regain, the treatment should be considered long-term.
This perspective is echoed by pharmaceutical companies, who note that the findings "underscore the long-term nature of obesity," comparing it to managing conditions like hypertension.
Patient Accounts
People who have come off the jabs explain a sudden resurgence of appetite.
"It felt as if a trigger flipping and I was suddenly ravenous," described a patient.
This difficulty is compounded if patients have not established permanent dietary or behavioural changes during therapy.
Significant Interest
Recent estimates show that millions of people in the UK have tried weight-loss jabs in the last 12 months, with desire continuing to grow.
- Use is higher among females compared to men.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
In conclusion, clinicians stress that while these medications are powerful agents for weight loss, they are not a permanent solution and long-term success hinges on ongoing behavioural support.
