Fresh analysis reveals that patients who stop using blockbuster GLP-1 drugs like Mounjaro or Wegovy may regain shed pounds at a significantly accelerated pace than those who end conventional lifestyle programs.
Published data in a major health publication demonstrates that while obese individuals often shed about a fifth of their total mass while on the medication, the weight returns at an estimated rate of nearly a kilo each month after stopping.
"Individuals using these drugs must be aware of the risk of rapid weight regain when the treatment ends," cautioned expert Dr. Susan Jebb.
This pace of recovery implies a reversion to original mass in about a year and a half.
Analyzing Approaches
The analysis, which examined dozens of trials involving thousands of participants, compared the results of the injectable medications with conventional dieting.
The team note that people who shed pounds through diet and exercise typically have a slower creep back—around 100 grams monthly—after stopping.
Understanding the Fast Regain
Doctors believe the way of the jabs accounts for the heightened weight return.
The injections copy a natural hormone called GLP-1, which moderates feelings of fullness.
"Long-term administration of the hormone concentrations several times higher than the body's typical production could lead to the system to produce less of its own natural hormone, and may also reduce sensitivity to its effects," explained Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this hormone supplement leads to hunger is unsuppressed, making binge eating a significant risk."
An Ongoing Issue?
Medical guidelines suggest the jabs for individuals with weight-linked health risks, accompanied by prescribed lifestyle changes.
Many experts argue that, considering the high risk of weight regain, the treatment might need to be ongoing.
This opinion is reinforced by pharmaceutical companies, who say that the results "highlight the persistent nature of excess weight," comparing it to managing diseases like high blood pressure.
User Accounts
People who have come off the medication explain a sudden resurgence of hunger.
"It felt as if a trigger flipping and I was suddenly starving," recalled one woman.
This challenge is exacerbated if patients have not established lasting dietary or behavioural modifications during therapy.
Growing Adoption
Recent estimates suggest that a significant number of adults in the UK have used these injections in the past year, with interest being substantial.
- Use is more common among women compared to males.
- The 40s and 50s demographic shows the highest level of interest.
- Many access the medications through private prescriptions rather than public health services.
In conclusion, clinicians caution that while these medications are potent tools for shedding pounds, they are not a standalone fix and long-term success likely depends on combined behavioural management.
