Fresh analysis reveals that individuals who come off popular GLP-1 drugs like Mounjaro or Wegovy tend to recover shed pounds far faster than those who stop conventional diet and exercise regimens.
Findings released in a major health publication points out that while overweight people can lose a large proportion of their total mass while using the jabs, the weight returns at an estimated rate of 0.8 kg per month once they quit.
"Individuals purchasing such medications must be informed of the risk of fast rebound weight gain when the therapy is stopped," cautioned lead investigator Dr. Susan Jebb.
That rate of recovery implies a reversion to original mass in about a year and a half.
Analyzing Approaches
The analysis, which reviewed dozens of studies involving thousands of participants, contrasted the effects of these new drugs with older methods.
Researchers point out that individuals who shed pounds through diet and exercise usually see a less rapid creep back—around 0.1 kg a month—after stopping.
Understanding the Quick Rebound
Experts propose the mode of action of the injections is key to understanding the heightened rebound.
GLP-1 drugs imitate a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 concentrations far above than normal might result in the system to produce less of its endogenous GLP-1, and could diminish sensitivity to its effects," noted Dr. Adam Collins, a dietetics expert.
"Withdrawal of this GLP-1 'fix' results in appetite is uncontrolled, making excessive eating far more likely."
An Ongoing Issue?
The NHS advise the injections for individuals with obesity-related health risks, accompanied by prescribed lifestyle changes.
Professionals argue that, considering the significant potential of weight regain, the therapy should be considered ongoing.
This perspective is supported by drug manufacturers, who say that the findings "emphasize the long-term character of excess weight," comparing it to managing conditions like high blood pressure.
Patient Testimonies
Users who have stopped the medication describe a powerful resurgence of appetite.
"I experienced a switch flipping and you become ravenous," described a patient.
The struggle is exacerbated if individuals have not established lasting lifestyle or habit modifications during therapy.
Widespread Adoption
Recent estimates indicate that millions of people in the UK have tried these injections in the last 12 months, with desire continuing to grow.
- Use is greater among females than men.
- The 40s and 50s age group shows the highest level of interest.
- A large proportion access the drugs through private healthcare rather than public health services.
Ultimately, experts caution that while the jabs are powerful tools for shedding pounds, they are not a permanent fix and long-term success relies on ongoing lifestyle management.
