Fresh analysis indicates that patients who come off new weight-loss injections like semaglutide or tirzepatide tend to recover reduced body mass at a significantly accelerated pace than those who halt conventional diet and exercise programs.
Published data in a major health publication shows that while obese people can lose substantial amounts of their total mass while using the jabs, the mass comes back at an estimated rate of nearly a kilo each month once they quit.
"Individuals buying these medications should be aware of the risk of rapid weight regain when the medication is stopped," stated researcher Dr. Susan Jebb.
That rate of regain suggests a return to original weight within about a year and a half.
Comparing Approaches
The study, which reviewed dozens of studies involving thousands of patients, compared the effects of the injectable medications with conventional dieting.
Scientists note that people who lose weight through lifestyle changes alone generally have a less rapid creep back—around 0.1 kg a month—after stopping.
The Reason for the Fast Regain
Nutrition scientists propose the way of the injections explains the amplified rebound.
GLP-1 drugs mimic a natural hormone called glucagon-like peptide-1, which moderates feelings of fullness.
"Sustained high doses of the hormone concentrations far above than normal might result in the system to produce less of its own natural GLP-1, and could diminish sensitivity to its actions," explained Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' means hunger is uncontrolled, making binge eating much more probable."
An Ongoing Issue?
The NHS advise the injections for people with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
Professionals argue that, considering the significant potential of weight regain, the therapy might need to be life-long.
This opinion is supported by pharmaceutical companies, who note that the findings "emphasize the chronic character of obesity," akin to managing conditions like high blood pressure.
Patient Testimonies
Users who have discontinued the medication describe a powerful return of hunger.
"It felt as if something that goes on and you're instantly extremely hungry," said a patient.
The struggle is exacerbated if patients have not established permanent dietary or behavioural changes during treatment.
Growing Interest
Survey data show that a significant number of adults in the UK have used weight-loss jabs in the past year, with demand being substantial.
- Adoption is higher among women than men.
- The middle-aged demographic shows the highest usage rates.
- A large proportion access 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 magic cure and lasting health benefits likely depends on combined behavioural management.
