Fresh analysis indicates that individuals who come off blockbuster weight-loss injections like Mounjaro or Wegovy can put back on shed pounds at a significantly accelerated pace than those who halt traditional diet and exercise regimens.
Findings released in a leading medical journal points out that while overweight people frequently drop about a fifth of their body weight while using the jabs, the weight is regained at an average rate of 0.8 kg per month once they quit.
"People buying such treatments must be cognizant of the risk of quick rebound weight gain when the therapy is stopped," warns expert Dr. Susan Jebb.
Such speed of recovery suggests a reversion to pre-treatment weight in about a year and a half.
Analyzing Approaches
The research, which reviewed dozens of trials involving over 9,000 of participants, compared the outcomes of the injectable medications with other pills.
Researchers emphasize that people who shed pounds through diet and exercise generally experience a less rapid creep back—approximately 100 grams monthly—post-intervention.
Understanding the Quick Rebound
Experts propose the mechanism of the drugs is key to understanding the amplified weight return.
GLP-1 drugs imitate a natural hormone called GLP-1, which controls hunger.
"Sustained high doses of the hormone concentrations several times higher than normal may cause the body to produce less of its endogenous hormone, and may also diminish responsiveness to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this medication means appetite is no longer kept in check, making binge eating much more probable."
A Chronic Disease?
The NHS advise the injections for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Many experts argue that, considering the likelihood of weight regain, the treatment is often long-term.
This opinion is reinforced by pharmaceutical companies, who state that the findings "highlight the persistent nature of excess weight," comparing it to managing conditions like high blood pressure.
User Accounts
Individuals who have discontinued the medication describe a intense return of hunger.
"It felt as if a trigger flipping and I was suddenly ravenous," said a patient.
This difficulty is exacerbated if users have not adopted permanent dietary or behavioural changes during therapy.
Widespread Adoption
Figures suggest that a significant number of people in the UK have used weight-loss jabs in the past year, with demand remaining high.
- Adoption is higher among females compared to men.
- The middle-aged age group shows the highest level of interest.
- Many access the medications through private healthcare rather than the NHS.
Ultimately, clinicians caution that while these medications are effective tools for weight loss, they are not a magic cure and maintained weight loss hinges on combined behavioural support.
