Fresh analysis indicates that people who come off popular GLP-1 drugs like Mounjaro or Wegovy can put back on lost weight at a significantly accelerated pace than those who stop conventional lifestyle programs.
Findings released in a prominent medical journal shows that while overweight individuals frequently drop about a fifth of their total mass while undergoing treatment, the weight is regained at an estimated rate of 0.8 kg per month upon discontinuation.
"People using such drugs need to be informed of the potential of fast rebound weight gain when the medication concludes," cautioned expert Dr. Susan Jebb.
Such speed of recovery implies a reversion to original mass in about a year and a half.
Analyzing Approaches
The analysis, which examined 37 of trials involving thousands of patients, contrasted the effects of these new drugs with other pills.
Researchers emphasize that people who lose weight through lifestyle changes alone usually have a slower creep back—around 100 grams monthly—post-intervention.
Understanding the Rapid Rebound
Experts suggest the mechanism of the injections is key to understanding the heightened rebound.
These medications imitate a natural hormone called GLP-1, which moderates appetite.
"Artificially providing the hormone concentrations far above than the body's typical production may cause the system to generate a reduced amount of its own natural GLP-1, and could diminish responsiveness to its actions," said Dr. Adam Collins, a nutrition specialist.
"Discontinuation of this GLP-1 'fix' leads to hunger is no longer kept in check, making overeating a significant risk."
A Chronic Issue?
Health authorities suggest the jabs for people with obesity-related health risks, accompanied by recommended lifestyle changes.
Professionals say that, given the significant potential of relapse, the treatment might need to be ongoing.
This perspective is echoed by drug manufacturers, who say that the findings "underscore the persistent nature of excess weight," akin to managing conditions like high blood pressure.
Patient Experiences
Individuals who have discontinued the medication explain a sudden return of appetite.
"It felt as if a trigger that goes on and you're instantly extremely hungry," described one woman.
This difficulty is worsened if individuals have not developed permanent lifestyle or habit modifications during therapy.
Widespread Interest
Recent estimates show that a significant number of people in the UK have tried these injections in the last 12 months, with desire continuing to grow.
- Use is greater among women than males.
- The middle-aged demographic shows the highest level of interest.
- A large proportion access the medications through private prescriptions rather than the NHS.
In conclusion, experts stress that while the jabs are potent tools for shedding pounds, they are not a magic fix and maintained weight loss relies on ongoing behavioural support.
