Fresh analysis indicates that patients who come off new slimming jabs like Mounjaro or Wegovy can put back on lost weight far faster than those who stop conventional diet and exercise plans.
Findings released in a prominent health publication points out that while obese people can lose substantial amounts of their total mass while undergoing treatment, the mass comes back at an estimated rate of 0.8 kg per month after stopping.
"People using these medications need to be informed of the potential of quick weight regain when the therapy is stopped," cautioned lead investigator Dr. Susan Jebb.
That rate of recovery suggests a return to pre-treatment weight in about a year and a half.
Analyzing Therapies
The research, which examined dozens of trials involving thousands of participants, contrasted the outcomes of GLP-1 agonists with older methods.
Scientists emphasize that individuals who shed pounds through lifestyle changes alone generally see a more gradual creep back—perhaps 0.1 kg a month—post-intervention.
Explaining the Fast Regain
Nutrition scientists believe the mode of action of the jabs explains the amplified regain.
The injections copy a natural hormone called glucagon-like peptide-1, which controls appetite.
"Artificially providing GLP-1 levels far above than the body's typical production could lead to the body to generate a reduced amount of its endogenous GLP-1, and could lessen responsiveness to its effects," said Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this medication means appetite is no longer kept in check, making binge eating much more probable."
A Lifelong Issue?
The NHS recommend the injections for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Professionals say that, considering the significant potential of weight regain, the treatment might need to be ongoing.
This perspective is supported by drug manufacturers, who note that the findings "emphasize the chronic nature of obesity," comparing it to managing diseases like diabetes.
Patient Testimonies
People who have come off the jabs explain a powerful resurgence of hunger.
"I experienced a switch that goes on and you're instantly extremely hungry," said a patient.
This difficulty is compounded if users have not established permanent lifestyle or habit changes during treatment.
Widespread Adoption
Survey data show that millions of people in the UK have used weight-loss jabs in the last 12 months, with demand continuing to grow.
- Adoption is more common among females than men.
- The 40s and 50s age group shows the highest level of interest.
- A large proportion access the medications through private prescriptions rather than public health services.
In conclusion, experts stress that while GLP-1 drugs are effective agents for weight loss, they are not a permanent cure and lasting health benefits likely depends on combined behavioural management.
