Fresh analysis indicates that people who come off popular weight-loss injections like Mounjaro or Wegovy tend to recover lost weight at a significantly accelerated pace than those who end conventional diet and exercise plans.
Findings released in a major health publication demonstrates that while overweight individuals often shed a large proportion of their total mass while using the jabs, the mass comes back at an average rate of nearly a kilo each month upon discontinuation.
"Individuals using these medications need to be informed of the danger of quick rebound weight gain when the treatment ends," cautioned researcher Dr. Susan Jebb.
That rate of regain suggests a return to starting mass within about 18 months.
Weighing Approaches
The analysis, which looked at dozens of studies involving over 9,000 of participants, contrasted the outcomes of these new drugs with other pills.
Scientists note that individuals who lose weight through lifestyle changes alone typically experience a slower creep back—around 100 grams monthly—post-intervention.
Understanding the Quick Regain
Nutrition scientists believe the way of the drugs accounts for the amplified regain.
GLP-1 drugs copy a body's own chemical called GLP-1, which controls hunger.
"Long-term administration of the hormone levels several times higher than normal could lead to the body to generate a reduced amount of its own natural GLP-1, and may also reduce responsiveness to its actions," said Dr. Adam Collins, a nutrition expert.
"Discontinuation of this medication means hunger is unsuppressed, making overeating far more likely."
A Lifelong Disease?
Medical guidelines suggest the jabs for people with weight-linked health risks, accompanied by recommended lifestyle changes.
A number of clinicians say that, considering the high risk of relapse, the therapy is often long-term.
This view is supported by pharmaceutical companies, who say that the findings "emphasize the long-term nature of obesity," similar to managing diseases like diabetes.
User Accounts
Individuals who have discontinued the medication describe a sudden return of appetite.
"It was like a switch flipping and you're instantly extremely hungry," said one woman.
This difficulty is worsened if patients have not developed permanent lifestyle or habit changes during treatment.
Widespread Use
Figures indicate that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with demand remaining high.
- Adoption is higher among women than males.
- The 40s and 50s demographic shows the greatest usage rates.
- A large proportion obtain the medications through private healthcare rather than the NHS.
Ultimately, researchers stress that while GLP-1 drugs are effective tools for shedding pounds, they are not a magic solution and lasting health benefits hinges on combined lifestyle changes.
