New research suggests that people who discontinue popular slimming jabs like semaglutide or tirzepatide may regain shed pounds far faster than those who stop traditional lifestyle programs.
Findings released in a major health publication points out that while overweight people frequently drop about a fifth of their body weight while on the medication, the mass is regained at an average rate of nearly a kilo each month after stopping.
"Users using such drugs must be aware of the potential of rapid weight regain when the medication is stopped," warns expert Dr. Susan Jebb.
That rate of regain means a reversion to pre-treatment mass in about a year and a half.
Comparing Therapies
The research, which looked at 37 of trials involving thousands of participants, contrasted the outcomes of GLP-1 agonists with other pills.
The team note that people who lose weight through lifestyle changes alone generally see a more gradual weight regain—perhaps 100 grams monthly—post-intervention.
Understanding the Fast Regain
Doctors believe the mechanism of the jabs is key to understanding the accelerated regain.
The injections mimic a body's own chemical called glucagon-like peptide-1, which moderates appetite.
"Long-term administration of the hormone concentrations several times higher than normal might result in the body to generate a reduced amount of its endogenous GLP-1, and may also lessen responsiveness to its actions," said Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this GLP-1 'fix' leads to appetite is no longer kept in check, making excessive eating much more probable."
A Lifelong Condition?
Medical guidelines suggest the injections for people with weight-linked health risks, accompanied by recommended lifestyle changes.
Many experts contend that, given the significant potential of relapse, the treatment should be considered ongoing.
This opinion is echoed by pharmaceutical companies, who say that the findings "underscore the long-term nature of obesity," comparing it to managing diseases like hypertension.
User Testimonies
Users who have stopped the jabs explain a intense resurgence of hunger.
"It was like something that goes on and I was suddenly ravenous," recalled one woman.
This challenge is worsened if individuals have not established lasting lifestyle or habit changes during therapy.
Widespread Interest
Figures indicate that millions of people in the UK have used weight-loss jabs in the last 12 months, with interest being substantial.
- Use is greater among females than men.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
Ultimately, researchers stress that while GLP-1 drugs are powerful tools for weight loss, they are not a magic solution and lasting health benefits hinges on ongoing lifestyle changes.
