New research reveals that individuals who discontinue blockbuster weight-loss injections like Mounjaro or Wegovy can put back on reduced body mass much more quickly than those who halt traditional lifestyle regimens.
Published data in a major medical journal shows that while obese people frequently drop substantial amounts of their body weight while on the medication, the weight comes back at an average rate of 0.8 kg per month once they quit.
"Individuals purchasing these drugs must be aware of the potential of fast weight regain when the medication is stopped," warns researcher Dr. Susan Jebb.
That rate of recovery implies a reversion to original mass in about one and a half years.
Weighing Treatments
The research, which looked at dozens of trials involving thousands of participants, compared the results of these new drugs with other pills.
The team emphasize that individuals who lose weight through diet and exercise usually experience a slower creep back—approximately 100 grams monthly—post-intervention.
Explaining the Fast Rebound
Doctors propose the way of the drugs is key to understanding the accelerated rebound.
GLP-1 drugs mimic a body's own chemical called GLP-1, which helps regulate appetite.
"Artificially providing GLP-1 concentrations far above than normal might result in the body to produce less of its own natural GLP-1, and may also reduce responsiveness to its effects," explained Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this GLP-1 'fix' leads to hunger is uncontrolled, making excessive eating a significant risk."
A Chronic Issue?
The NHS recommend the injections for individuals with obesity-related health risks, accompanied by prescribed diet and exercise modifications.
Professionals argue that, given the likelihood of weight regain, the treatment should be considered ongoing.
This perspective is echoed by pharmaceutical companies, who state that the findings "underscore the persistent nature of obesity," akin to managing conditions like hypertension.
User Accounts
Users who have come off the jabs describe a powerful resurgence of appetite.
"It felt as if a switch that goes on and I was suddenly extremely hungry," said an individual.
This difficulty is worsened if individuals have not established sustainable dietary or behavioural changes during treatment.
Significant Use
Figures indicate that millions of people in the UK have used weight-loss jabs in the last 12 months, with demand continuing to grow.
- Use is greater among women compared to males.
- The middle-aged demographic shows the greatest usage rates.
- Many access the drugs through private prescriptions rather than the NHS.
In conclusion, clinicians stress that while these medications are potent tools for shedding pounds, they are not a permanent fix and long-term success relies on integrated behavioural support.
