A recent study reveals that individuals who discontinue new GLP-1 drugs like semaglutide or tirzepatide may regain lost weight much more quickly than those who end traditional diet and exercise programs.
Published data in a major medical journal shows that while overweight people often shed substantial amounts of their total mass while on the medication, the mass is regained at an average rate of 0.8 kg per month upon discontinuation.
"Users purchasing these drugs must be aware of the danger of fast weight regain when the medication is stopped," stated researcher Dr. Susan Jebb.
Such speed of recovery implies a reversion to original mass in about one and a half years.
Weighing Approaches
The analysis, which reviewed dozens of studies involving thousands of participants, compared the effects of the injectable medications with older methods.
Scientists note that individuals who lose weight through lifestyle changes alone generally have a slower creep back—around 100 grams monthly—once they finish.
Explaining the Rapid Regain
Nutrition scientists propose the mechanism of the jabs explains the amplified rebound.
The injections copy a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Artificially providing the hormone concentrations far above than the body's typical production could lead to the system to produce less of its endogenous hormone, and could lessen responsiveness to its effects," explained Dr. Adam Collins, a dietetics expert.
"Stopping of this GLP-1 'fix' means appetite is unsuppressed, making excessive eating far more likely."
A Lifelong Disease?
Health authorities advise the injections for people with weight-linked health risks, accompanied by recommended diet and exercise modifications.
Professionals contend that, given the significant potential of weight regain, the therapy is often life-long.
This perspective is reinforced by pharmaceutical companies, who say that the results "underscore the persistent character of obesity," similar to managing diseases like diabetes.
User Testimonies
Users who have stopped the medication describe a powerful resurgence of cravings.
"I experienced something activating and you become extremely hungry," recalled a patient.
This challenge is exacerbated if users have not adopted permanent dietary or behavioural modifications during treatment.
Widespread Interest
Recent estimates show that millions of adults in the UK have used these injections in the past year, with desire remaining high.
- Use is greater among women than males.
- The 40s and 50s age group shows the highest level of interest.
- Many access the medications through private prescriptions rather than public health services.
In conclusion, experts emphasize that while the jabs are potent tools for weight loss, they are not a standalone fix and long-term success likely depends on combined behavioural support.
