A recent study indicates that patients who stop using blockbuster slimming jabs like semaglutide or tirzepatide can put back on shed pounds at a significantly accelerated pace than those who halt conventional lifestyle regimens.
Published data in a prominent medical journal shows that while overweight individuals often shed substantial amounts of their total mass while undergoing treatment, the weight is regained at an estimated rate of nearly a kilo each month once they quit.
"Users purchasing these drugs need to be aware of the potential of rapid weight regain when the therapy ends," cautioned lead investigator Dr. Susan Jebb.
Such speed of regain implies a return to pre-treatment mass in about a year and a half.
Comparing Approaches
The analysis, which looked at 37 of trials involving thousands of participants, contrasted the effects of these new drugs with older methods.
Scientists note that people who lose weight through diet and exercise usually see a less rapid weight regain—around 0.1 kg a month—once they finish.
Understanding the Fast Rebound
Experts suggest the way of the drugs is key to understanding the heightened weight return.
The injections copy a body's own chemical called glucagon-like peptide-1, which controls hunger.
"Long-term administration of the hormone levels far above than the body's typical production could lead to the system to generate a reduced amount of its own natural hormone, and could lessen sensitivity to its effects," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this GLP-1 'fix' results in appetite is unsuppressed, making excessive eating a significant risk."
A Lifelong Disease?
Health authorities suggest the injections for individuals with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals argue that, considering the high risk of weight regain, the treatment should be considered life-long.
This opinion is supported by drug manufacturers, who state that the findings "emphasize the chronic nature of obesity," akin to managing diseases like hypertension.
Patient Experiences
Individuals who have stopped the jabs describe a powerful return of cravings.
"I experienced a trigger that goes on and you're instantly extremely hungry," said an individual.
This difficulty is compounded if individuals have not established sustainable lifestyle or habit changes during treatment.
Growing Use
Figures suggest that a significant number of adults in the UK have used weight-loss jabs in the past year, with desire continuing to grow.
- Use is more common among females compared to men.
- The middle-aged demographic shows the greatest usage rates.
- Many access the drugs through private healthcare rather than public health services.
In conclusion, researchers stress that while these medications are powerful agents for weight loss, they are not a standalone cure and lasting health benefits hinges on ongoing behavioural changes.
