Fresh analysis suggests 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 conventional diet and exercise programs.
Findings released in a prominent health publication demonstrates that while overweight people often shed about a fifth of their body weight while undergoing treatment, the mass returns at an average rate of nearly a kilo each month upon discontinuation.
"Users using these medications must be aware of the danger of fast weight regain when the medication ends," warns lead investigator Dr. Susan Jebb.
That rate of regain suggests a return to original mass in about a year and a half.
Weighing Therapies
The research, which examined dozens of trials involving over 9,000 of patients, compared the effects of the injectable medications with older methods.
Researchers point out that individuals who shed pounds through lifestyle changes alone generally experience a slower weight regain—perhaps 0.1 kg a month—post-intervention.
The Reason for the Quick Rebound
Experts suggest the way of the injections is key to understanding the amplified regain.
GLP-1 drugs copy 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 system to generate a reduced amount of its own natural GLP-1, and may also lessen sensitivity to its actions," noted Dr. Adam Collins, a dietetics expert.
"Stopping of this hormone supplement leads to appetite is unsuppressed, making overeating much more probable."
A Lifelong Issue?
The NHS suggest the injections for people with obesity-related health risks, alongside recommended diet and exercise modifications.
Professionals say that, considering the likelihood of weight regain, the treatment is often ongoing.
This opinion is supported by drug manufacturers, who note that the results "highlight the persistent nature of excess weight," similar to managing diseases like hypertension.
Patient Testimonies
People who have discontinued the medication explain a sudden resurgence of appetite.
"It was like a trigger flipping and I was suddenly extremely hungry," recalled a patient.
This difficulty is worsened if patients have not established lasting lifestyle or habit changes during therapy.
Significant Use
Recent estimates suggest that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with interest continuing to grow.
- Adoption is more common among women compared to men.
- The middle-aged demographic shows the highest level of interest.
- A large proportion obtain the drugs through private healthcare rather than public health services.
Ultimately, experts emphasize that while the jabs are powerful agents for shedding pounds, they are not a magic cure and lasting health benefits relies on integrated lifestyle management.
