A recent study suggests that people who come off blockbuster GLP-1 drugs like semaglutide or tirzepatide may regain shed pounds far faster than those who stop conventional lifestyle programs.
Findings released in a prominent health publication demonstrates that while obese people often shed substantial amounts of their body weight while undergoing treatment, the mass returns at an average rate of 0.8 kg per month upon discontinuation.
"People buying such medications should be informed of the risk of fast rebound weight gain when the therapy ends," stated expert Dr. Susan Jebb.
This pace of recovery means a reversion to original mass in about a year and a half.
Weighing Approaches
The research, which examined 37 of trials involving over 9,000 of patients, compared the effects of the injectable medications with conventional dieting.
The team emphasize that individuals who lose weight through dieting typically have a slower weight regain—perhaps 0.1 kg a month—once they finish.
Explaining the Fast Rebound
Doctors propose the mode of action of the injections explains the accelerated regain.
These medications copy a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of the hormone concentrations several times higher than the body's typical production could lead to the system to generate a reduced amount of its own natural GLP-1, and may also diminish responsiveness to its effects," noted Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this GLP-1 'fix' means hunger is unsuppressed, making excessive eating much more probable."
A Lifelong Condition?
Medical guidelines suggest the jabs for people with weight-linked health risks, alongside recommended lifestyle changes.
A number of clinicians argue that, considering the significant potential of weight regain, the treatment might need to be ongoing.
This opinion is supported by pharmaceutical companies, who state that the results "highlight the persistent nature of excess weight," akin to managing conditions like diabetes.
Patient Accounts
Users who have discontinued the medication explain a powerful return of hunger.
"I experienced a trigger activating and you're instantly starving," described an individual.
The struggle is exacerbated if individuals have not established lasting lifestyle or habit modifications during therapy.
Widespread Interest
Recent estimates show that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with desire continuing to grow.
- Use is more common among females compared to males.
- The 40s and 50s demographic shows the greatest level of interest.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
In conclusion, experts stress that while these medications are powerful agents for shedding pounds, they are not a magic fix and maintained weight loss hinges on ongoing lifestyle support.
