A recent study reveals that individuals who discontinue blockbuster GLP-1 drugs like Mounjaro or Wegovy may regain reduced body mass much more quickly than those who stop conventional diet and exercise plans.
Research printed in a prominent medical journal demonstrates that while obese individuals often shed substantial amounts of their total mass while undergoing treatment, the mass comes back at an estimated rate of 0.8 kg per month after stopping.
"Individuals buying such medications should be aware of the potential of rapid rebound weight gain when the medication ends," cautioned researcher Dr. Susan Jebb.
That rate of regain suggests a reversion to starting mass within about 18 months.
Comparing Therapies
The analysis, which examined dozens of trials involving thousands of participants, contrasted the effects of GLP-1 agonists with conventional dieting.
The team point out that people who shed pounds through dieting usually have a less rapid creep back—around 0.1 kg a month—post-intervention.
Explaining the Quick Regain
Experts suggest the mechanism of the injections accounts for the amplified regain.
The injections mimic a natural hormone called glucagon-like peptide-1, which moderates feelings of fullness.
"Sustained high doses of the hormone levels several times higher than the body's typical production could lead to the system to generate a reduced amount of its own natural GLP-1, and may also reduce responsiveness to its effects," noted Dr. Adam Collins, a nutrition researcher.
"Stopping of this GLP-1 'fix' leads to appetite is unsuppressed, making overeating a significant risk."
A Lifelong Issue?
The NHS suggest the jabs for people with weight-linked medical conditions, accompanied by recommended diet and exercise modifications.
Many experts contend that, considering the significant potential of relapse, the therapy might need to be life-long.
This view is reinforced by pharmaceutical companies, who note that the findings "underscore the persistent character of excess weight," comparing it to managing diseases like diabetes.
Patient Testimonies
Individuals who have stopped the medication describe a intense return of hunger.
"It was like something that goes on and you're instantly extremely hungry," said an individual.
This challenge is compounded if users have not established permanent dietary or behavioural changes during treatment.
Widespread Interest
Recent estimates indicate that millions of adults in the UK have used these injections in the last 12 months, with interest continuing to grow.
- Use is more common among women than men.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
In conclusion, researchers stress that while GLP-1 drugs are effective agents for shedding pounds, they are not a magic fix and long-term success relies on integrated lifestyle changes.
