Fresh analysis indicates that patients who discontinue blockbuster GLP-1 drugs like Wegovy and Mounjaro may regain reduced body mass at a significantly accelerated pace than those who end traditional lifestyle plans.
Research printed in a leading health publication points out that while obese people frequently drop substantial amounts of their body weight while undergoing treatment, the weight is regained at an average rate of 0.8 kg per month once they quit.
"Individuals buying such medications need to be cognizant of the potential of fast weight regain when the medication is stopped," cautioned expert Dr. Susan Jebb.
That rate of regain implies a reversion to pre-treatment mass in about a year and a half.
Comparing Approaches
The research, which examined dozens of studies involving over 9,000 of participants, contrasted the results of these new drugs with older methods.
Scientists note that people who shed pounds through lifestyle changes alone generally see a slower creep back—around 100 grams monthly—after stopping.
Understanding the Quick Regain
Experts believe the mechanism of the jabs explains the heightened weight return.
These medications mimic a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Long-term administration of the hormone levels several times higher than the body's typical production might result in the body to generate a reduced amount of its own natural GLP-1, and may also reduce sensitivity to its effects," noted Dr. Adam Collins, a dietetics expert.
"Discontinuation of this GLP-1 'fix' leads to hunger is unsuppressed, making excessive eating far more likely."
A Lifelong Issue?
The NHS recommend the jabs for people with weight-linked health risks, alongside recommended lifestyle changes.
Professionals argue that, given the high risk of relapse, the treatment might need to be long-term.
This opinion is echoed by drug manufacturers, who say that the findings "highlight the persistent nature of excess weight," comparing it to managing diseases like hypertension.
User Accounts
People who have discontinued the medication report a sudden resurgence of appetite.
"It felt as if a trigger that goes on and I was suddenly ravenous," recalled one woman.
The struggle is exacerbated if users have not established sustainable lifestyle or habit changes during treatment.
Growing Interest
Survey data suggest that millions of adults in the UK have used weight-loss jabs in the past year, with interest being substantial.
- Use is more common among females compared to men.
- The 40s and 50s age group shows the greatest usage rates.
- Many obtain the drugs through private prescriptions rather than the NHS.
Ultimately, researchers stress that while the jabs are effective tools for shedding pounds, they are not a magic cure and long-term success hinges on integrated lifestyle changes.
