Fresh analysis indicates that patients who stop using popular weight-loss injections like Mounjaro or Wegovy may regain reduced body mass much more quickly than those who end traditional diet and exercise programs.
Findings released in a leading health publication shows that while overweight people often shed about a fifth of their total mass while using the jabs, the weight returns at an average rate of nearly a kilo each month upon discontinuation.
"People using such drugs should be aware of the potential of fast rebound weight gain when the treatment ends," stated expert Dr. Susan Jebb.
This pace of regain implies a return to starting mass within about one and a half years.
Comparing Approaches
The study, which reviewed 37 of trials involving thousands of participants, compared the outcomes of GLP-1 agonists with older methods.
Researchers point out that people who shed pounds through diet and exercise generally experience a slower creep back—approximately 100 grams monthly—after stopping.
The Reason for the Fast Regain
Nutrition scientists propose the mechanism of the injections accounts for the amplified rebound.
GLP-1 drugs copy a body's own chemical called glucagon-like peptide-1, which helps regulate hunger.
"Sustained high doses of GLP-1 levels far above than normal might result in the system to generate a reduced amount of its endogenous GLP-1, and could diminish responsiveness to its actions," noted Dr. Adam Collins, a nutrition expert.
"Discontinuation of this hormone supplement leads to appetite is uncontrolled, making binge eating a significant risk."
A Chronic Condition?
Medical guidelines recommend the injections for people with obesity-related medical conditions, alongside prescribed lifestyle changes.
Many experts contend that, due to the likelihood of weight regain, the treatment should be considered life-long.
This view is reinforced by drug manufacturers, who state that the results "highlight the long-term nature of excess weight," similar to managing diseases like high blood pressure.
User Accounts
Individuals who have stopped the medication report a powerful return of hunger.
"I experienced something activating and you become extremely hungry," recalled a patient.
The struggle is exacerbated if patients have not established lasting lifestyle or habit modifications during therapy.
Significant Interest
Survey data show that a significant number of adults in the UK have used these injections in the past year, with desire continuing to grow.
- Adoption is more common among women compared to males.
- The 40s and 50s age group shows the highest level of interest.
- Many obtain the medications through private prescriptions rather than the NHS.
In conclusion, clinicians emphasize that while GLP-1 drugs are potent agents for shedding pounds, they are not a standalone cure and lasting health benefits likely depends on ongoing lifestyle management.
