A recent study indicates that people who come off popular slimming jabs like Mounjaro or Wegovy may regain reduced body mass at a significantly accelerated pace than those who halt conventional diet and exercise programs.
Published data in a major medical journal points out that while obese individuals can lose substantial amounts of their body weight while on the medication, the weight returns at an average rate of nearly a kilo each month upon discontinuation.
"Individuals using such drugs need to be cognizant of the risk of fast rebound weight gain when the treatment ends," warns lead investigator Dr. Susan Jebb.
This pace of recovery implies a return to pre-treatment mass in about 18 months.
Weighing Therapies
The analysis, which reviewed dozens of studies involving thousands of participants, compared the effects of these new drugs with older methods.
Researchers note that people who lose weight through lifestyle changes alone typically experience a less rapid weight regain—approximately 100 grams monthly—once they finish.
Understanding the Fast Regain
Nutrition scientists propose the way of the drugs explains the amplified weight return.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Long-term administration of the hormone levels far above than normal could lead to the system to produce less of its own natural hormone, and could reduce responsiveness to its effects," explained Dr. Adam Collins, a nutrition expert.
"Discontinuation of this GLP-1 'fix' results in hunger is unsuppressed, making overeating far more likely."
A Lifelong Disease?
The NHS suggest the jabs for individuals with obesity-related health risks, alongside prescribed diet and exercise modifications.
A number of clinicians argue that, considering the likelihood of relapse, the therapy is often ongoing.
This opinion is echoed by pharmaceutical companies, who say that the findings "emphasize the chronic nature of excess weight," comparing it to managing diseases like high blood pressure.
Patient Experiences
Users who have come off the medication explain a powerful resurgence of appetite.
"I experienced a trigger that goes on and you become extremely hungry," said an individual.
The struggle is worsened if users have not developed sustainable lifestyle or habit modifications during therapy.
Widespread Adoption
Recent estimates suggest that a significant number of adults in the UK have tried weight-loss jabs in the last 12 months, with desire being substantial.
- Adoption is greater among females than males.
- The 40s and 50s age group shows the highest usage rates.
- Many access the medications through private healthcare rather than public health services.
In conclusion, clinicians emphasize that while GLP-1 drugs are potent agents for shedding pounds, they are not a permanent cure and long-term success likely depends on integrated lifestyle management.
