Fresh analysis suggests that people who discontinue popular slimming jabs like Mounjaro or Wegovy tend to recover shed pounds far faster than those who end traditional diet and exercise regimens.
Research printed in a major medical journal demonstrates that while obese people frequently drop about a fifth of their body weight while on the medication, the weight returns at an average rate of 0.8 kg per month after stopping.
"People purchasing such treatments must be informed of the danger of rapid rebound weight gain when the treatment concludes," warns researcher Dr. Susan Jebb.
Such speed of regain means a return to starting weight in about 18 months.
Weighing Treatments
The study, which reviewed dozens of studies involving thousands of patients, compared the outcomes of GLP-1 agonists with older methods.
Scientists note that people who lose weight through lifestyle changes alone generally experience a more gradual weight regain—approximately 100 grams monthly—once they finish.
Understanding the Quick Regain
Doctors suggest the mode of action of the jabs accounts for the amplified rebound.
GLP-1 drugs mimic a body's own chemical called GLP-1, which helps regulate appetite.
"Long-term administration of the hormone levels several times higher than normal might result in the body to produce less of its own natural GLP-1, and may also reduce sensitivity to its actions," said Dr. Adam Collins, a dietetics expert.
"Stopping of this hormone supplement means hunger is unsuppressed, making binge eating far more likely."
An Ongoing Disease?
Health authorities advise the jabs for people with weight-linked medical conditions, alongside recommended diet and exercise modifications.
A number of clinicians contend that, due to the significant potential of weight regain, the therapy should be considered life-long.
This perspective is reinforced by pharmaceutical companies, who note that the findings "emphasize the persistent nature of excess weight," similar to managing diseases like diabetes.
User Testimonies
People who have come off the medication explain a powerful resurgence of cravings.
"It was like something that goes on and you become ravenous," described one woman.
This difficulty is exacerbated if users have not established lasting dietary or behavioural changes during treatment.
Significant Interest
Figures indicate that millions of adults in the UK have tried weight-loss jabs in the past year, with desire continuing to grow.
- Use is more common among females compared to males.
- The middle-aged demographic shows the greatest usage rates.
- Many access the drugs through private healthcare rather than public health services.
In conclusion, experts stress that while GLP-1 drugs are powerful tools for shedding pounds, they are not a magic cure and long-term success relies on integrated behavioural management.
