A recent study indicates that patients who discontinue popular weight-loss injections like semaglutide or tirzepatide tend to recover shed pounds much more quickly than those who stop conventional diet and exercise programs.
Findings released in a major health publication points out that while obese individuals often shed a large proportion of their body weight while undergoing treatment, the mass is regained at an average rate of 0.8 kg per month upon discontinuation.
"People purchasing these medications must be informed of the danger of fast weight regain when the therapy is stopped," cautioned expert Dr. Susan Jebb.
This pace of recovery means a reversion to original weight within about 18 months.
Weighing Approaches
The research, which reviewed dozens of trials involving thousands of participants, contrasted the outcomes of these new drugs with older methods.
Scientists point out that people who shed pounds through dieting typically experience a less rapid weight regain—approximately 100 grams monthly—once they finish.
Understanding the Fast Rebound
Doctors propose the mechanism of the injections explains the heightened rebound.
These medications imitate a natural hormone called GLP-1, which moderates appetite.
"Sustained high doses of the hormone levels far above than the body's typical production may cause the system to generate a reduced amount of its own natural GLP-1, and may also reduce sensitivity to its effects," explained Dr. Adam Collins, a nutrition researcher.
"Stopping of this hormone supplement results in appetite is no longer kept in check, making excessive eating a significant risk."
An Ongoing Disease?
Health authorities suggest the jabs for people with obesity-related health risks, alongside recommended lifestyle changes.
A number of clinicians contend that, due to the significant potential of relapse, the therapy is often long-term.
This view is echoed by drug manufacturers, who say that the findings "emphasize the long-term character of obesity," akin to managing diseases like hypertension.
User Experiences
Users who have stopped the medication explain a sudden return of appetite.
"I experienced a trigger flipping and you're instantly extremely hungry," recalled an individual.
The struggle is compounded if users have not established sustainable dietary or behavioural changes during therapy.
Significant Interest
Recent estimates indicate that millions of people in the UK have tried these injections in the past year, with interest continuing to grow.
- Use is higher among females than men.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion access the medications through private healthcare rather than the NHS.
In conclusion, clinicians stress that while GLP-1 drugs are effective agents for shedding pounds, they are not a magic fix and maintained weight loss hinges on ongoing lifestyle management.
