Fresh analysis indicates that people who come off popular GLP-1 drugs like semaglutide or tirzepatide can put back on shed pounds much more quickly than those who stop conventional diet and exercise programs.
Published data in a leading health publication demonstrates that while overweight people often shed a large proportion of their body weight while undergoing treatment, the mass is regained at an estimated rate of 0.8 kg per month upon discontinuation.
"People purchasing these medications need to be aware of the risk of quick weight regain when the medication ends," warns researcher Dr. Susan Jebb.
Such speed of regain means a reversion to starting mass in about one and a half years.
Comparing Treatments
The analysis, which examined 37 of trials involving thousands of participants, contrasted the results of the injectable medications with older methods.
Researchers emphasize that individuals who shed pounds through diet and exercise usually see a more gradual weight regain—perhaps 0.1 kg a month—post-intervention.
Explaining the Fast Regain
Doctors propose the way of the drugs is key to understanding the heightened rebound.
The injections mimic a body's own chemical called glucagon-like peptide-1, which controls feelings of fullness.
"Artificially providing the hormone concentrations far above than the body's typical production could lead to the body to produce less of its endogenous hormone, and may also lessen sensitivity to its actions," noted Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this medication leads to hunger is no longer kept in check, making excessive eating far more likely."
An Ongoing Issue?
Medical guidelines advise the injections for people with weight-linked medical conditions, alongside recommended lifestyle changes.
Professionals contend that, due to the likelihood of weight regain, the therapy should be considered life-long.
This view is reinforced by drug manufacturers, who state that the results "highlight the chronic character of obesity," akin to managing conditions like hypertension.
User Testimonies
Users who have stopped the jabs explain a intense return of appetite.
"It was like something activating and I was suddenly ravenous," said an individual.
The struggle is worsened if patients have not established sustainable lifestyle or habit changes during therapy.
Widespread Interest
Recent estimates indicate that millions of adults in the UK have used these injections in the past year, with desire remaining high.
- Use is more common among females than males.
- The 40s and 50s demographic shows the greatest usage rates.
- Many access the drugs through private prescriptions rather than public health services.
Finally, experts stress that while the jabs are powerful agents for weight loss, they are not a magic cure and long-term success relies on integrated lifestyle changes.
