A recent study indicates that patients who come off popular GLP-1 drugs like Mounjaro or Wegovy tend to recover lost weight much more quickly than those who end traditional lifestyle programs.
Findings released in a prominent medical journal demonstrates that while overweight people frequently drop a large proportion of their total mass while on the medication, the weight comes back at an estimated rate of nearly a kilo each month once they quit.
"Users using these medications must be cognizant of the risk of fast weight regain when the treatment concludes," stated expert Dr. Susan Jebb.
Such speed of recovery implies a reversion to original weight in about a year and a half.
Comparing Approaches
The research, which examined dozens of studies involving thousands of patients, compared the outcomes of the injectable medications with older methods.
Scientists note that people who lose weight through lifestyle changes alone typically have a less rapid weight regain—approximately 100 grams monthly—once they finish.
Understanding the Rapid Regain
Experts suggest the mechanism of the injections is key to understanding the heightened rebound.
GLP-1 drugs imitate a natural hormone called glucagon-like peptide-1, which moderates appetite.
"Sustained high doses of GLP-1 levels far above than normal might result in the body to generate a reduced amount of its own natural GLP-1, and may also reduce sensitivity to its actions," noted Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement means appetite is uncontrolled, making binge eating much more probable."
A Chronic Disease?
Health authorities recommend the injections for people with weight-linked health risks, accompanied by recommended lifestyle changes.
Professionals contend that, considering the high risk of relapse, the treatment might need to be life-long.
This opinion is reinforced by pharmaceutical companies, who note that the results "underscore the long-term nature of obesity," similar to managing conditions like diabetes.
User Accounts
Individuals who have discontinued the jabs describe a sudden return of hunger.
"It felt as if something flipping and I was suddenly extremely hungry," recalled a patient.
This difficulty is exacerbated if individuals have not developed lasting dietary or behavioural changes during therapy.
Widespread Adoption
Survey data suggest that millions of people in the UK have tried weight-loss jabs in the past year, with demand continuing to grow.
- Adoption is higher among females than males.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion obtain the medications through private healthcare rather than the NHS.
Finally, researchers stress that while these medications are powerful tools for shedding pounds, they are not a magic solution and lasting health benefits relies on ongoing lifestyle changes.
