A recent study indicates that people who come off popular weight-loss injections like Mounjaro or Wegovy may regain reduced body mass at a significantly accelerated pace than those who halt traditional diet and exercise plans.
Published data in a major health publication points out that while overweight individuals can lose a large proportion of their total mass while using the jabs, the weight comes back at an average rate of 0.8 kg per month once they quit.
"Users using these treatments must be cognizant of the danger of quick rebound weight gain when the treatment concludes," warns expert Dr. Susan Jebb.
Such speed of recovery implies a reversion to original weight in about a year and a half.
Analyzing Approaches
The study, which reviewed dozens of trials involving over 9,000 of patients, contrasted the effects of GLP-1 agonists with older methods.
Researchers note that individuals who lose weight through lifestyle changes alone typically see a less rapid weight regain—approximately 0.1 kg a month—post-intervention.
Explaining the Quick Regain
Doctors believe the mechanism of the drugs is key to understanding the accelerated regain.
These medications copy a natural hormone called GLP-1, which moderates hunger.
"Artificially providing GLP-1 levels far above than the body's typical production could lead to the system to generate a reduced amount of its own natural hormone, and may also reduce responsiveness to its actions," said Dr. Adam Collins, a dietetics specialist.
"Stopping of this GLP-1 'fix' leads to appetite is uncontrolled, making excessive eating far more likely."
An Ongoing Issue?
Health authorities recommend the jabs for people with weight-linked medical conditions, accompanied by prescribed lifestyle changes.
Professionals contend that, due to the high risk of relapse, the therapy might need to be long-term.
This opinion is supported by drug manufacturers, who say that the findings "underscore the persistent character of excess weight," comparing it to managing diseases like diabetes.
User Accounts
Users who have stopped the medication describe a intense return of hunger.
"It was like a switch flipping and I was suddenly starving," recalled a patient.
The struggle is compounded if users have not established permanent lifestyle or habit changes during therapy.
Widespread Interest
Survey data show that millions of adults in the UK have tried these injections in the last 12 months, with demand remaining high.
- Use is higher among females compared to males.
- The middle-aged demographic shows the highest usage rates.
- Many access the medications through private healthcare rather than the NHS.
In conclusion, researchers stress that while these medications are potent tools for weight loss, they are not a magic fix and lasting health benefits relies on ongoing lifestyle support.
