Fresh analysis indicates that people who discontinue new weight-loss injections like Wegovy and Mounjaro tend to recover reduced body mass far faster than those who stop traditional lifestyle programs.
Research printed in a prominent medical journal points out that while overweight individuals often shed about a fifth of their total mass while undergoing treatment, the weight returns at an average rate of nearly a kilo each month after stopping.
"People buying such drugs should be informed of the risk of rapid weight regain when the therapy is stopped," warns lead investigator Dr. Susan Jebb.
That rate of regain suggests a reversion to original weight within about a year and a half.
Analyzing Approaches
The study, which examined 37 of studies involving over 9,000 of participants, contrasted the effects of these new drugs with conventional dieting.
Scientists emphasize that individuals who lose weight through dieting usually see a less rapid creep back—perhaps 100 grams monthly—post-intervention.
Understanding the Fast Rebound
Doctors suggest the mode of action of the injections is key to understanding the accelerated weight return.
These medications mimic a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Artificially providing GLP-1 concentrations several times higher than the body's typical production might result in the body to produce less of its endogenous GLP-1, and could reduce sensitivity to its actions," noted Dr. Adam Collins, a dietetics expert.
"Withdrawal of this GLP-1 'fix' results in hunger is uncontrolled, making overeating a significant risk."
A Lifelong Disease?
The NHS recommend the injections for individuals with weight-linked health risks, accompanied by recommended lifestyle changes.
Professionals contend that, considering the likelihood of relapse, the therapy might need to be life-long.
This view is supported by pharmaceutical companies, who say that the results "emphasize the long-term character of excess weight," comparing it to managing conditions like diabetes.
Patient Testimonies
Users who have discontinued the jabs describe a intense resurgence of appetite.
"It felt as if a trigger activating and you're instantly starving," said a patient.
The struggle is worsened if users have not developed lasting lifestyle or habit modifications during therapy.
Widespread Use
Recent estimates indicate that millions of adults in the UK have tried weight-loss jabs in the past year, with desire continuing to grow.
- Use is more common among women compared to males.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
Ultimately, experts emphasize that while GLP-1 drugs are effective tools for weight loss, they are not a magic solution and maintained weight loss relies on integrated lifestyle support.
