A recent study indicates that patients who discontinue popular GLP-1 drugs like Mounjaro or Wegovy may regain reduced body mass far faster than those who end traditional lifestyle plans.
Published data in a prominent health publication demonstrates that while overweight individuals can lose a large proportion of their body weight while undergoing treatment, the weight comes back at an average rate of nearly a kilo each month once they quit.
"Users using these drugs need to be informed of the danger of fast weight regain when the medication concludes," warns researcher Dr. Susan Jebb.
Such speed of recovery means a return to original mass within about a year and a half.
Weighing Treatments
The research, which reviewed dozens of studies involving over 9,000 of participants, contrasted the outcomes of these new drugs with older methods.
Scientists point out that people who lose weight through diet and exercise generally have a more gradual creep back—perhaps 100 grams monthly—post-intervention.
The Reason for the Quick Rebound
Experts propose the way of the jabs accounts for the heightened rebound.
The injections imitate a body's own chemical called GLP-1, which moderates appetite.
"Artificially providing the hormone concentrations several times higher than normal might result in the system to produce less of its endogenous hormone, and could diminish responsiveness to its actions," explained Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this hormone supplement results in hunger is no longer kept in check, making overeating far more likely."
An Ongoing Condition?
Health authorities advise the injections for individuals with obesity-related medical conditions, alongside prescribed diet and exercise modifications.
Professionals contend that, due to the significant potential of weight regain, the therapy might need to be long-term.
This perspective is supported by drug manufacturers, who say that the results "emphasize the long-term nature of obesity," akin to managing diseases like diabetes.
Patient Experiences
Individuals who have stopped the jabs report a sudden resurgence of hunger.
"It felt as if something that goes on and you become ravenous," described a patient.
The struggle is exacerbated if users have not established permanent dietary or behavioural modifications during treatment.
Significant Interest
Recent estimates show that millions of people in the UK have tried weight-loss jabs in the past year, with desire being substantial.
- Adoption is more common among females than males.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion access the medications through private healthcare rather than the NHS.
In conclusion, experts emphasize that while the jabs are effective agents for weight loss, they are not a permanent fix and lasting health benefits relies on integrated behavioural management.
