A recent study reveals that individuals who discontinue new weight-loss injections like Wegovy and Mounjaro may regain reduced body mass at a significantly accelerated pace than those who end traditional diet and exercise plans.
Findings released in a leading health publication points out that while overweight people frequently drop substantial amounts of their total mass while on the medication, the mass returns at an average rate of nearly a kilo each month after stopping.
"Individuals buying these medications need to be aware of the risk of fast weight regain when the medication concludes," warns researcher Dr. Susan Jebb.
That rate of regain means a reversion to starting weight in about 18 months.
Weighing Treatments
The research, which looked at dozens of studies involving over 9,000 of participants, compared the outcomes of these new drugs with conventional dieting.
Scientists note that people who lose weight through lifestyle changes alone generally have a less rapid weight regain—around 100 grams monthly—once they finish.
The Reason for the Rapid Regain
Nutrition scientists suggest the mode of action of the injections explains the accelerated rebound.
These medications imitate a natural hormone called GLP-1, which helps regulate hunger.
"Artificially providing GLP-1 concentrations far above than normal could lead to the body to generate a reduced amount of its endogenous hormone, and may also lessen responsiveness to its actions," explained Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this medication results in hunger is uncontrolled, making binge eating far more likely."
A Chronic Disease?
Medical guidelines recommend the injections for individuals with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
A number of clinicians argue that, considering the high risk of relapse, the treatment should be considered long-term.
This view is supported by pharmaceutical companies, who say that the findings "emphasize the long-term character of excess weight," akin to managing diseases like hypertension.
User Experiences
People who have stopped the medication explain a sudden return of appetite.
"It was like something activating and you become ravenous," recalled a patient.
This difficulty is worsened if users have not developed permanent lifestyle or habit modifications during treatment.
Significant Interest
Survey data indicate that millions of adults in the UK have used these injections in the last 12 months, with desire remaining high.
- Adoption is higher among women compared to males.
- The 40s and 50s age group shows the highest level of interest.
- Many obtain the medications through private healthcare rather than the NHS.
In conclusion, experts emphasize that while these medications are powerful tools for weight loss, they are not a standalone cure and maintained weight loss relies on combined behavioural management.
