New research reveals that individuals who stop using blockbuster GLP-1 drugs like semaglutide or tirzepatide tend to recover lost weight far faster than those who stop traditional diet and exercise programs.
Findings released in a prominent medical journal points out that while obese individuals frequently drop about a fifth of their total mass while on the medication, the mass comes back at an average rate of nearly a kilo each month upon discontinuation.
"Individuals buying such medications should be cognizant of the risk of rapid rebound weight gain when the treatment is stopped," warns researcher Dr. Susan Jebb.
Such speed of recovery implies a reversion to pre-treatment weight in about a year and a half.
Comparing Approaches
The analysis, which looked at dozens of trials involving over 9,000 of participants, compared the effects of GLP-1 agonists with older methods.
Researchers point out that people who shed pounds through lifestyle changes alone generally experience a more gradual creep back—around 0.1 kg a month—once they finish.
The Reason for the Rapid Regain
Doctors suggest the mechanism of the injections accounts for the heightened regain.
The injections imitate a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Sustained high doses of GLP-1 levels several times higher than the body's typical production may cause the system to generate a reduced amount of its own natural hormone, and could diminish sensitivity to its actions," explained Dr. Adam Collins, a nutrition specialist.
"Stopping of this GLP-1 'fix' leads to hunger is unsuppressed, making excessive eating far more likely."
An Ongoing Condition?
Health authorities advise the injections for people with weight-linked medical conditions, alongside prescribed lifestyle changes.
Professionals contend that, due to the high risk of relapse, the therapy should be considered life-long.
This perspective is echoed by pharmaceutical companies, who state that the findings "underscore the long-term nature of obesity," similar to managing conditions like high blood pressure.
User Accounts
Users who have discontinued the medication explain a intense return of hunger.
"It was like a trigger activating and you're instantly ravenous," described a patient.
This difficulty is worsened if individuals have not developed sustainable lifestyle or habit modifications during treatment.
Significant Interest
Survey data suggest that a significant number of adults in the UK have tried these injections in the past year, with desire remaining high.
- Adoption is more common among women compared to males.
- The middle-aged age group shows the highest usage rates.
- A large proportion access the medications through private healthcare rather than public health services.
In conclusion, researchers caution that while the jabs are powerful agents for weight loss, they are not a permanent solution and lasting health benefits likely depends on combined lifestyle changes.
