Fresh analysis reveals that individuals who discontinue popular GLP-1 drugs like semaglutide or tirzepatide tend to recover reduced body mass far faster than those who halt conventional diet and exercise regimens.
Published data in a leading medical journal points out that while overweight people frequently drop substantial amounts of their body weight while undergoing treatment, the weight comes back at an average rate of 0.8 kg per month upon discontinuation.
"Users using such drugs should be informed of the potential of quick rebound weight gain when the medication concludes," stated lead investigator Dr. Susan Jebb.
This pace of recovery suggests a reversion to starting weight within about 18 months.
Analyzing Treatments
The study, which looked at 37 of studies involving thousands of participants, contrasted the effects of these new drugs with other pills.
Researchers point out that people who shed pounds through dieting typically experience a slower weight regain—approximately 0.1 kg a month—after stopping.
Explaining the Fast Rebound
Nutrition scientists propose the way of the drugs is key to understanding the accelerated weight return.
These medications imitate a body's own chemical called GLP-1, which moderates appetite.
"Long-term administration of the hormone concentrations several times higher than normal could lead to the body to produce less of its endogenous GLP-1, and could reduce sensitivity to its effects," noted Dr. Adam Collins, a dietetics expert.
"Stopping of this hormone supplement results in appetite is unsuppressed, making binge eating much more probable."
A Chronic Disease?
Health authorities suggest the injections for people with weight-linked health risks, alongside prescribed lifestyle changes.
Professionals contend that, given the high risk of weight regain, the treatment is often ongoing.
This view is supported by pharmaceutical companies, who say that the findings "highlight the chronic nature of excess weight," akin to managing conditions like diabetes.
User Experiences
Users who have stopped the jabs explain a sudden resurgence of cravings.
"I experienced a trigger that goes on and you're instantly starving," described an individual.
The struggle is worsened if users have not established sustainable lifestyle or habit modifications during therapy.
Growing Interest
Recent estimates suggest that millions of people in the UK have tried these injections in the last 12 months, with interest continuing to grow.
- Use is greater among females compared to males.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the medications through private prescriptions rather than the NHS.
In conclusion, experts stress that while the jabs are potent agents for shedding pounds, they are not a permanent fix and long-term success likely depends on integrated behavioural changes.
