Fresh analysis suggests that individuals who stop using popular slimming jabs like Mounjaro or Wegovy can put back on lost weight at a significantly accelerated pace than those who stop conventional diet and exercise programs.
Published data in a leading medical journal shows that while overweight people often shed about a fifth of their body weight while undergoing treatment, the weight is regained at an estimated rate of nearly a kilo each month once they quit.
"People using such treatments must be cognizant of the risk of rapid rebound weight gain when the therapy concludes," cautioned lead investigator Dr. Susan Jebb.
Such speed of regain implies a reversion to original mass within about one and a half years.
Analyzing Treatments
The analysis, which looked at dozens of trials involving thousands of patients, compared the results of the injectable medications with conventional dieting.
Researchers note that individuals who shed pounds through dieting generally see a more gradual creep back—around 0.1 kg a month—after stopping.
Explaining the Fast Regain
Nutrition scientists propose the way of the drugs accounts for the heightened weight return.
The injections copy a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Long-term administration of the hormone concentrations far above than the body's typical production may cause the system to generate a reduced amount of its own natural hormone, and could diminish responsiveness to its effects," explained Dr. Adam Collins, a dietetics expert.
"Withdrawal of this GLP-1 'fix' leads to hunger is no longer kept in check, making overeating a significant risk."
A Lifelong Disease?
The NHS recommend the jabs for individuals with weight-linked health risks, alongside prescribed lifestyle changes.
Many experts say that, given the high risk of relapse, the treatment is often life-long.
This perspective is supported by drug manufacturers, who say that the findings "emphasize the persistent character of excess weight," akin to managing diseases like hypertension.
User Experiences
Individuals who have stopped the medication describe a sudden return of appetite.
"It felt as if a trigger that goes on and you become extremely hungry," said a patient.
This challenge is exacerbated if patients have not established permanent lifestyle or habit changes during therapy.
Widespread Interest
Survey data indicate that a significant number of adults in the UK have used these injections in the last 12 months, with interest continuing to grow.
- Use is more common among women than men.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion obtain the medications through private prescriptions rather than public health services.
In conclusion, clinicians caution that while GLP-1 drugs are powerful agents for weight loss, they are not a magic cure and long-term success likely depends on integrated lifestyle changes.
