Fresh analysis indicates that individuals who come off popular GLP-1 drugs like Mounjaro or Wegovy can put back on lost weight much more quickly than those who stop conventional diet and exercise regimens.
Published data in a prominent health publication shows that while overweight individuals can lose a large proportion of their total mass while using the jabs, the weight comes back at an average rate of 0.8 kg per month upon discontinuation.
"Users purchasing these medications must be aware of the potential of fast weight regain when the medication concludes," warns lead investigator Dr. Susan Jebb.
That rate of regain means a reversion to starting mass within about one and a half years.
Comparing Therapies
The study, which reviewed 37 of trials involving thousands of patients, compared the results of the injectable medications with older methods.
The team emphasize that people who shed pounds through diet and exercise generally see a more gradual creep back—around 100 grams monthly—after stopping.
Understanding the Quick Rebound
Nutrition scientists suggest the way of the jabs accounts for the accelerated regain.
These medications mimic a body's own chemical called glucagon-like peptide-1, which controls hunger.
"Long-term administration of the hormone concentrations several times higher than normal could lead to the body to produce less of its endogenous GLP-1, and could reduce sensitivity to its actions," explained Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this GLP-1 'fix' means appetite is no longer kept in check, making overeating a significant risk."
An Ongoing Issue?
The NHS suggest the injections for people with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
A number of clinicians argue that, considering the high risk of relapse, the treatment might need to be life-long.
This perspective is echoed by pharmaceutical companies, who state that the results "emphasize the chronic nature of obesity," similar to managing diseases like high blood pressure.
User Experiences
Individuals who have stopped the medication describe a sudden return of hunger.
"I experienced a switch that goes on and I was suddenly extremely hungry," described one woman.
This difficulty is worsened if individuals have not established lasting lifestyle or habit modifications during therapy.
Significant Use
Recent estimates suggest that a significant number of adults in the UK have used these injections in the last 12 months, with demand being substantial.
- Adoption is greater among females compared to males.
- The middle-aged demographic shows the highest level of interest.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
In conclusion, experts stress that while the jabs are effective agents for shedding pounds, they are not a permanent fix and lasting health benefits relies on combined lifestyle support.
