New research suggests that patients who come off popular weight-loss injections like Mounjaro or Wegovy may regain reduced body mass at a significantly accelerated pace than those who stop traditional lifestyle programs.
Findings released in a leading health publication points out that while overweight people frequently drop a large proportion of their total mass while undergoing treatment, the mass returns at an average rate of nearly a kilo each month upon discontinuation.
"Individuals using these drugs should be cognizant of the potential of quick rebound weight gain when the treatment ends," stated expert Dr. Susan Jebb.
This pace of recovery means a return to original weight in about a year and a half.
Weighing Treatments
The research, which reviewed 37 of studies involving thousands of patients, compared the outcomes of these new drugs with other pills.
Scientists point out that people who shed pounds through lifestyle changes alone generally have a less rapid creep back—approximately 100 grams monthly—after stopping.
Explaining the Quick Regain
Experts believe the way of the drugs explains the heightened rebound.
These medications imitate a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 levels far above than normal could lead to the system to generate a reduced amount of its own natural GLP-1, and may also lessen responsiveness to its effects," said Dr. Adam Collins, a nutrition expert.
"Discontinuation of this medication leads to appetite is unsuppressed, making binge eating far more likely."
An Ongoing Condition?
Medical guidelines suggest the jabs for people with weight-linked medical conditions, alongside recommended lifestyle changes.
Professionals contend that, considering the high risk of relapse, the treatment is often ongoing.
This perspective is supported by pharmaceutical companies, who say that the results "highlight the long-term nature of obesity," similar to managing diseases like hypertension.
Patient Experiences
Users who have discontinued the medication report a intense return of cravings.
"I experienced a trigger activating and I was suddenly extremely hungry," recalled a patient.
The struggle is exacerbated if individuals have not adopted permanent lifestyle or habit changes during therapy.
Growing Interest
Figures suggest that a significant number of people in the UK have used weight-loss jabs in the past year, with demand being substantial.
- Use is higher among females compared to males.
- The middle-aged demographic shows the highest usage rates.
- A large proportion access the medications through private prescriptions rather than public health services.
Ultimately, clinicians stress that while the jabs are potent agents for shedding pounds, they are not a standalone fix and lasting health benefits relies on ongoing lifestyle changes.
