New research reveals that people who come off new weight-loss injections like Mounjaro or Wegovy may regain reduced body mass much more quickly than those who end conventional diet and exercise regimens.
Findings released in a major medical journal shows that while obese people frequently drop substantial amounts of their body weight while undergoing treatment, the mass returns at an estimated rate of 0.8 kg per month upon discontinuation.
"Individuals using such treatments should be aware of the danger of quick weight regain when the medication is stopped," cautioned researcher Dr. Susan Jebb.
This pace of regain implies a return to starting weight within about 18 months.
Weighing Approaches
The analysis, which reviewed dozens of studies involving over 9,000 of participants, contrasted the effects of the injectable medications with other pills.
Scientists note that people who lose weight through diet and exercise generally see a slower weight regain—around 0.1 kg a month—post-intervention.
Explaining the Rapid Regain
Experts suggest the mode of action of the injections is key to understanding the accelerated rebound.
The injections copy a body's own chemical called glucagon-like peptide-1, which moderates feelings of fullness.
"Long-term administration of the hormone levels several times higher than the body's typical production may cause the body to generate a reduced amount of its endogenous GLP-1, and may also lessen responsiveness to its actions," noted Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this GLP-1 'fix' results in appetite is uncontrolled, making overeating far more likely."
A Chronic Issue?
Medical guidelines recommend the jabs for individuals with obesity-related health risks, accompanied by prescribed lifestyle changes.
Professionals argue that, given the high risk of weight regain, the therapy is often life-long.
This view is supported by drug manufacturers, who say that the results "emphasize the long-term character of obesity," comparing it to managing conditions like hypertension.
User Testimonies
Users who have come off the medication describe a powerful return of appetite.
"It was like a switch activating and I was suddenly starving," recalled a patient.
This difficulty is worsened if individuals have not adopted lasting lifestyle or habit modifications during therapy.
Significant Use
Recent estimates show that millions of adults in the UK have used these injections in the past year, with desire being substantial.
- Use is greater among women than men.
- The 40s and 50s demographic shows the highest usage rates.
- Many obtain the medications through private prescriptions rather than public health services.
In conclusion, researchers stress that while GLP-1 drugs are powerful agents for shedding pounds, they are not a standalone solution and lasting health benefits likely depends on combined lifestyle changes.
