Fresh analysis reveals that people who stop using popular weight-loss injections like semaglutide or tirzepatide tend to recover lost weight at a significantly accelerated pace than those who halt conventional diet and exercise programs.
Published data in a leading health publication shows that while overweight people often shed 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.
"People buying such medications should be cognizant of the potential of rapid weight regain when the treatment ends," warns researcher Dr. Susan Jebb.
This pace of regain means a reversion to pre-treatment weight in about 18 months.
Comparing Approaches
The analysis, which reviewed 37 of studies involving thousands of patients, compared the results of GLP-1 agonists with conventional dieting.
Scientists emphasize that people who shed pounds through diet and exercise generally have a slower weight regain—around 0.1 kg a month—after stopping.
The Reason for the Rapid Rebound
Nutrition scientists suggest the mechanism of the drugs explains the amplified rebound.
These medications mimic a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Long-term administration of GLP-1 levels several times higher than the body's typical production might result in 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 researcher.
"Discontinuation of this GLP-1 'fix' leads to hunger is no longer kept in check, making excessive eating a significant risk."
An Ongoing Disease?
The NHS advise the injections for people with weight-linked health risks, alongside recommended lifestyle changes.
A number of clinicians contend that, given the likelihood of weight regain, the therapy might need to be life-long.
This view is reinforced by drug manufacturers, who note that the results "highlight the persistent nature of obesity," akin to managing conditions like high blood pressure.
Patient Accounts
People who have come off the jabs report a intense resurgence of hunger.
"It was like a trigger that goes on and you're instantly ravenous," recalled one woman.
The struggle is worsened if individuals have not developed sustainable lifestyle or habit changes during therapy.
Widespread Interest
Figures indicate that a significant number of adults in the UK have used weight-loss jabs in the last 12 months, with demand being substantial.
- Use is more common among females compared to men.
- The 40s and 50s demographic shows the greatest usage rates.
- Many obtain the medications through private healthcare rather than the NHS.
In conclusion, clinicians stress that while the jabs are potent agents for shedding pounds, they are not a permanent solution and lasting health benefits hinges on integrated behavioural management.
