A recent study indicates that patients who come off blockbuster GLP-1 drugs like semaglutide or tirzepatide may regain reduced body mass much more quickly than those who stop conventional lifestyle programs.
Findings released in a leading health publication demonstrates that while obese individuals can lose a large proportion of their total mass while using the jabs, the mass is regained at an estimated rate of 0.8 kg per month upon discontinuation.
"Individuals using these drugs must be aware of the risk of fast rebound weight gain when the treatment is stopped," warns lead investigator Dr. Susan Jebb.
That rate of recovery implies a reversion to starting weight in about 18 months.
Analyzing Treatments
The analysis, which examined 37 of studies involving thousands of participants, contrasted the results of GLP-1 agonists with conventional dieting.
Researchers note that people who lose weight through diet and exercise typically experience a less rapid creep back—approximately 100 grams monthly—after stopping.
Explaining the Rapid Regain
Experts propose the way of the jabs is key to understanding the amplified regain.
The injections imitate a natural hormone called glucagon-like peptide-1, which controls feelings of fullness.
"Artificially providing the hormone levels several times higher than normal might result in the body to produce less of its endogenous hormone, and could diminish responsiveness to its effects," explained Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this GLP-1 'fix' leads to hunger is uncontrolled, making binge eating a significant risk."
A Chronic Disease?
The NHS suggest the jabs for individuals with weight-linked health risks, accompanied by prescribed lifestyle changes.
Professionals say that, given the likelihood of relapse, the treatment is often long-term.
This perspective is echoed by pharmaceutical companies, who note that the findings "underscore the persistent character of excess weight," similar to managing conditions like diabetes.
Patient Experiences
People who have stopped the medication explain a intense resurgence of appetite.
"It was like something activating and I was suddenly extremely hungry," said one woman.
The struggle is exacerbated if individuals have not adopted permanent dietary or behavioural modifications during treatment.
Growing Interest
Figures indicate that a significant number of adults in the UK have used these injections in the past year, with desire continuing to grow.
- Use is more common among women compared to men.
- The 40s and 50s demographic shows the greatest level of interest.
- Many obtain the medications through private healthcare rather than the NHS.
In conclusion, experts stress that while these medications are potent agents for shedding pounds, they are not a standalone solution and long-term success relies on combined lifestyle support.
