New research indicates that individuals who stop using popular weight-loss injections like Mounjaro or Wegovy can put back on lost weight far faster than those who halt conventional diet and exercise plans.
Research printed in a leading health publication points out that while overweight individuals frequently drop substantial amounts of their body weight while on the medication, the weight is regained at an average rate of 0.8 kg per month upon discontinuation.
"People using these medications should be informed of the danger of fast weight regain when the treatment ends," cautioned researcher Dr. Susan Jebb.
This pace of regain means a reversion to original weight in about one and a half years.
Weighing Approaches
The analysis, which examined dozens of trials involving thousands of patients, contrasted the results of GLP-1 agonists with conventional dieting.
Scientists emphasize that people who shed pounds through lifestyle changes alone usually see a more gradual creep back—approximately 0.1 kg a month—post-intervention.
Understanding the Quick Rebound
Nutrition scientists suggest the mode of action of the jabs accounts for the accelerated rebound.
GLP-1 drugs imitate a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 concentrations far above than normal could lead to the system to generate a reduced amount of its own natural GLP-1, and may also reduce responsiveness to its actions," explained Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this GLP-1 'fix' results in hunger is unsuppressed, making excessive eating far more likely."
A Chronic Disease?
Medical guidelines recommend the injections for individuals with weight-linked health risks, alongside prescribed lifestyle changes.
A number of clinicians argue that, considering the significant potential of relapse, the therapy might need to be life-long.
This view is echoed by drug manufacturers, who note that the findings "underscore the long-term character of obesity," similar to managing diseases like diabetes.
Patient Experiences
People who have stopped the medication explain a sudden resurgence of cravings.
"It felt as if a switch flipping and I was suddenly starving," said an individual.
This difficulty is worsened if individuals have not established lasting dietary or behavioural modifications during therapy.
Significant Adoption
Recent estimates 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 more common among females than men.
- The middle-aged age group shows the highest usage rates.
- Many access the drugs through private healthcare rather than public health services.
In conclusion, researchers stress that while GLP-1 drugs are powerful tools for weight loss, they are not a standalone fix and lasting health benefits hinges on combined lifestyle management.
