Fresh analysis indicates that patients who stop using popular weight-loss injections like Wegovy and Mounjaro tend to recover shed pounds at a significantly accelerated pace than those who end traditional diet and exercise plans.
Findings released in a major medical journal shows that while obese individuals often shed substantial amounts of their body weight while using the jabs, the weight comes back at an average rate of 0.8 kg per month after stopping.
"Individuals buying such medications should be informed of the danger of quick rebound weight gain when the medication ends," cautioned researcher Dr. Susan Jebb.
This pace of regain suggests a return to original weight in about one and a half years.
Weighing Approaches
The study, which examined 37 of trials involving thousands of patients, contrasted the effects of the injectable medications with other pills.
Scientists note that people who lose weight through lifestyle changes alone usually experience a slower creep back—around 100 grams monthly—post-intervention.
Explaining the Fast Regain
Experts suggest the way of the drugs explains the amplified weight return.
GLP-1 drugs mimic a natural hormone called GLP-1, which helps regulate hunger.
"Sustained high doses of the hormone levels far above than the body's typical production may cause the system to produce less of its endogenous hormone, and may also lessen sensitivity to its actions," noted Dr. Adam Collins, a nutrition expert.
"Withdrawal of this hormone supplement leads to hunger is unsuppressed, making excessive eating much more probable."
A Lifelong Issue?
The NHS advise the jabs for individuals with weight-linked health risks, alongside recommended diet and exercise modifications.
Many experts contend that, considering the high risk of weight regain, the therapy is often ongoing.
This opinion is reinforced by pharmaceutical companies, who note that the results "underscore the persistent nature of excess weight," comparing it to managing conditions like high blood pressure.
User Experiences
Individuals who have stopped the jabs explain a sudden return of hunger.
"It felt as if a trigger that goes on and I was suddenly extremely hungry," recalled a patient.
This difficulty is exacerbated if users have not established permanent dietary or behavioural changes during therapy.
Significant Interest
Figures show that millions of adults in the UK have used weight-loss jabs in the past year, with desire being substantial.
- Adoption is greater among females compared to men.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion obtain the medications through private healthcare rather than public health services.
Finally, experts caution that while these medications are potent agents for weight loss, they are not a standalone cure and long-term success hinges on ongoing lifestyle changes.
