Fresh analysis indicates that patients who stop using blockbuster slimming jabs like semaglutide or tirzepatide may regain shed pounds much more quickly than those who halt conventional lifestyle plans.
Published data in a prominent health publication shows that while obese individuals often shed about a fifth of their body weight while on the medication, the weight is regained at an estimated rate of nearly a kilo each month after stopping.
"Individuals buying such drugs need to be cognizant of the potential of fast weight regain when the treatment is stopped," stated expert Dr. Susan Jebb.
That rate of recovery implies a reversion to starting weight within about 18 months.
Comparing Treatments
The study, which looked at 37 of studies involving thousands of participants, contrasted the effects of GLP-1 agonists with conventional dieting.
Scientists note that people who shed pounds through diet and exercise generally have a less rapid weight regain—approximately 0.1 kg a month—post-intervention.
Explaining the Rapid Rebound
Doctors propose the mode of action of the injections accounts for the heightened regain.
The injections mimic a body's own chemical called GLP-1, which moderates hunger.
"Long-term administration of the hormone concentrations several times higher than the body's typical production could lead to the body to generate a reduced amount of its own natural hormone, and may also lessen responsiveness to its effects," noted Dr. Adam Collins, a nutrition expert.
"Withdrawal of this GLP-1 'fix' results in hunger is unsuppressed, making overeating a significant risk."
An Ongoing Condition?
Health authorities advise the jabs for individuals with weight-linked health risks, alongside prescribed lifestyle changes.
Many experts say that, considering the significant potential of weight regain, the therapy is often life-long.
This perspective is reinforced by pharmaceutical companies, who say that the results "emphasize the persistent character of excess weight," comparing it to managing conditions like diabetes.
Patient Testimonies
Users who have stopped the medication explain a powerful resurgence of cravings.
"It was like a trigger activating and you become extremely hungry," recalled a patient.
This difficulty is exacerbated if users have not established sustainable lifestyle or habit modifications during therapy.
Widespread Interest
Recent estimates suggest that a significant number of adults in the UK have used these injections in the last 12 months, with desire being substantial.
- Use is greater among females compared to men.
- The middle-aged age group shows the highest level of interest.
- Many access the drugs through private prescriptions rather than the NHS.
In conclusion, researchers emphasize that while the jabs are potent agents for weight loss, they are not a standalone solution and lasting health benefits relies on integrated lifestyle changes.
