Fresh analysis suggests that individuals who stop using popular slimming jabs like semaglutide or tirzepatide may regain lost weight at a significantly accelerated pace than those who end traditional lifestyle programs.
Published data in a prominent medical journal demonstrates that while overweight people can lose substantial amounts of their body weight while using the jabs, the mass is regained at an average rate of nearly a kilo each month upon discontinuation.
"Individuals purchasing such medications should be informed of the risk of rapid weight regain when the treatment concludes," stated lead investigator Dr. Susan Jebb.
That rate of recovery suggests a return to original weight in about one and a half years.
Analyzing Approaches
The analysis, which looked at 37 of trials involving thousands of participants, contrasted the effects of these new drugs with conventional dieting.
The team point out that people who lose weight through dieting typically have a less rapid creep back—perhaps 0.1 kg a month—post-intervention.
The Reason for the Fast Regain
Doctors propose the mode of action of the injections explains the heightened weight return.
These medications imitate a body's own chemical called GLP-1, which controls appetite.
"Artificially providing the hormone levels several times higher than the body's typical production could lead to the body to generate a reduced amount of its own natural GLP-1, and may also diminish sensitivity to its effects," said Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this GLP-1 'fix' means appetite is no longer kept in check, making overeating much more probable."
An Ongoing Disease?
The NHS suggest the jabs for individuals with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
A number of clinicians say that, due to the high risk of weight regain, the treatment might need to be long-term.
This view is echoed by drug manufacturers, who state that the results "emphasize the persistent nature of obesity," similar to managing conditions like high blood pressure.
Patient Experiences
Users who have come off the medication describe a intense resurgence of appetite.
"It was like a trigger flipping and you're instantly starving," described one woman.
The struggle is exacerbated if individuals have not adopted permanent dietary or behavioural modifications during treatment.
Widespread Interest
Survey data suggest that a significant number of adults in the UK have used these injections in the past year, with interest continuing to grow.
- Adoption is greater among women than males.
- The 40s and 50s age group shows the greatest usage rates.
- Many obtain the drugs through private healthcare rather than the NHS.
In conclusion, clinicians caution that while GLP-1 drugs are effective tools for shedding pounds, they are not a magic fix and lasting health benefits likely depends on combined lifestyle management.
