Fresh analysis reveals that patients who come off new GLP-1 drugs like semaglutide or tirzepatide may regain reduced body mass much more quickly than those who end traditional diet and exercise programs.
Published data in a leading medical journal demonstrates that while overweight individuals often shed substantial amounts of their total mass while on the medication, the mass is regained at an estimated rate of nearly a kilo each month after stopping.
"Individuals using such treatments must be aware of the potential of rapid weight regain when the therapy is stopped," cautioned expert Dr. Susan Jebb.
That rate of recovery suggests a return to starting weight within about 18 months.
Weighing Approaches
The analysis, which looked at 37 of trials involving over 9,000 of patients, compared the results of these new drugs with other pills.
Scientists point out that individuals who shed pounds through diet and exercise generally see a slower creep back—approximately 0.1 kg a month—after stopping.
Explaining the Rapid Regain
Nutrition scientists suggest the way of the jabs is key to understanding the amplified rebound.
The injections mimic a body's own chemical called GLP-1, which controls appetite.
"Artificially providing GLP-1 concentrations several times higher than normal may cause the body to produce less of its endogenous hormone, and could diminish responsiveness to its effects," explained Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this medication results in appetite is no longer kept in check, making binge eating far more likely."
An Ongoing Condition?
The NHS suggest the jabs for people with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
A number of clinicians say that, due to the significant potential of relapse, the treatment is often life-long.
This perspective is supported by drug manufacturers, who state that the results "emphasize the persistent nature of excess weight," akin to managing conditions like hypertension.
User Accounts
Individuals who have discontinued the medication report a sudden resurgence of cravings.
"It was like a switch flipping and you're instantly ravenous," described one woman.
This difficulty is compounded if individuals have not adopted sustainable dietary or behavioural modifications during treatment.
Significant Use
Recent estimates indicate that a significant number of adults in the UK have used these injections in the last 12 months, with desire remaining high.
- Adoption is more common among women compared to males.
- The middle-aged demographic shows the greatest usage rates.
- Many access the drugs through private healthcare rather than public health services.
In conclusion, clinicians stress that while the jabs are effective tools for shedding pounds, they are not a magic cure and lasting health benefits likely depends on combined lifestyle changes.
