Fresh analysis suggests that patients who come off popular weight-loss injections like Wegovy and Mounjaro tend to recover lost weight far faster than those who end conventional diet and exercise plans.
Published data in a major medical journal demonstrates that while overweight people can lose a large proportion of their total mass while undergoing treatment, the weight is regained at an estimated rate of nearly a kilo each month upon discontinuation.
"People using these medications need to be informed of the risk of rapid weight regain when the treatment concludes," stated researcher Dr. Susan Jebb.
This pace of recovery implies a return to pre-treatment weight within about a year and a half.
Weighing Therapies
The analysis, which examined dozens of studies involving over 9,000 of patients, contrasted the outcomes of these new drugs with other pills.
The team emphasize that people who shed pounds through lifestyle changes alone typically experience a slower weight regain—around 0.1 kg a month—after stopping.
The Reason for the Rapid Regain
Doctors suggest the way of the jabs accounts for the heightened regain.
The injections copy a body's own chemical called GLP-1, which controls hunger.
"Artificially providing the hormone levels far above than the body's typical production might result in the system to produce less of its own natural hormone, and may also reduce responsiveness to its effects," said Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this GLP-1 'fix' results in appetite is uncontrolled, making binge eating a significant risk."
A Chronic Condition?
Health authorities advise the jabs for people with obesity-related health risks, alongside prescribed lifestyle changes.
A number of clinicians contend that, due to the significant potential of weight regain, the treatment is often life-long.
This view is echoed by drug manufacturers, who state that the findings "underscore the long-term nature of excess weight," comparing it to managing conditions like hypertension.
Patient Testimonies
People who have come off the medication report a intense return of cravings.
"It felt as if a switch activating and I was suddenly ravenous," said an individual.
This challenge is compounded if patients have not adopted sustainable dietary or behavioural modifications during treatment.
Significant Adoption
Survey data show that millions of adults in the UK have used weight-loss jabs in the past year, with desire being substantial.
- Use is more common among females compared to men.
- The middle-aged age group shows the greatest level of interest.
- Many access the medications through private healthcare rather than public health services.
In conclusion, researchers emphasize that while GLP-1 drugs are powerful agents for shedding pounds, they are not a magic cure and lasting health benefits relies on combined lifestyle support.
