Fresh analysis suggests that individuals who come off popular GLP-1 drugs like semaglutide or tirzepatide may regain lost weight at a significantly accelerated pace than those who stop traditional lifestyle regimens.
Research printed in a major health publication points out that while overweight individuals often shed substantial amounts of their total mass while on the medication, the mass returns at an average rate of nearly a kilo each month upon discontinuation.
"Individuals using such treatments must be informed of the danger of quick rebound weight gain when the medication concludes," cautioned expert Dr. Susan Jebb.
This pace of recovery implies a return to starting mass in about one and a half years.
Comparing Approaches
The analysis, which looked at dozens of studies involving over 9,000 of participants, compared the results of these new drugs with older methods.
The team point out that people who shed pounds through dieting usually see a slower weight regain—approximately 0.1 kg a month—after stopping.
Explaining the Rapid Regain
Doctors suggest the mechanism of the drugs accounts for the heightened regain.
The injections imitate a body's own chemical called GLP-1, which helps regulate appetite.
"Long-term administration of the hormone levels several times higher than the body's typical production could lead to the system to produce less of its endogenous GLP-1, and could lessen sensitivity to its effects," explained Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this hormone supplement leads to appetite is no longer kept in check, making overeating much more probable."
A Chronic Issue?
Medical guidelines suggest the injections for people with obesity-related medical conditions, alongside prescribed diet and exercise modifications.
Professionals say that, considering the significant potential of weight regain, the treatment is often life-long.
This opinion is reinforced by pharmaceutical companies, who say that the results "highlight the long-term character of obesity," akin to managing conditions like diabetes.
User Testimonies
Users who have stopped the medication explain a intense resurgence of hunger.
"It was like a switch activating and you're instantly extremely hungry," said one woman.
The struggle is worsened if users have not adopted permanent dietary or behavioural modifications during treatment.
Widespread Use
Recent estimates suggest that millions of adults in the UK have used these injections in the last 12 months, with desire being substantial.
- Use is more common among females compared to men.
- The 40s and 50s demographic shows the highest usage rates.
- Many access the drugs through private prescriptions rather than public health services.
In conclusion, clinicians caution that while these medications are potent tools for weight loss, they are not a permanent solution and maintained weight loss relies on integrated lifestyle changes.
