New research indicates that people who come off new GLP-1 drugs like Mounjaro or Wegovy can put back on reduced body mass at a significantly accelerated pace than those who halt conventional lifestyle plans.
Findings released in a leading medical journal demonstrates that while obese individuals can lose substantial amounts 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 buying these drugs should be aware of the potential of fast rebound weight gain when the therapy is stopped," cautioned researcher Dr. Susan Jebb.
This pace of regain means a reversion to original weight within about a year and a half.
Weighing Approaches
The study, which looked at 37 of studies involving over 9,000 of participants, compared the effects of these new drugs with other pills.
Researchers note that individuals who lose weight through dieting usually have a more gradual creep back—perhaps 100 grams monthly—once they finish.
The Reason for the Fast Regain
Experts believe the mode of action of the jabs is key to understanding the accelerated rebound.
GLP-1 drugs copy a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 levels several times higher than normal might result in the system to generate a reduced amount of its own natural GLP-1, and may also reduce sensitivity to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this GLP-1 'fix' results in appetite is uncontrolled, making binge eating a significant risk."
A Lifelong Disease?
Health authorities recommend the injections for people with weight-linked health risks, alongside prescribed diet and exercise modifications.
A number of clinicians say that, due to the likelihood of weight regain, the treatment might need to be long-term.
This view is supported by drug manufacturers, who note that the results "emphasize the chronic nature of excess weight," akin to managing diseases like hypertension.
Patient Testimonies
People who have come off the medication describe a powerful resurgence of hunger.
"It was like a trigger flipping and you become extremely hungry," described a patient.
This challenge is exacerbated if patients have not adopted lasting lifestyle or habit modifications during therapy.
Widespread Adoption
Figures indicate that a significant number of adults in the UK have tried these injections in the past year, with desire being substantial.
- Adoption is greater among women than males.
- The middle-aged age group shows the highest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
In conclusion, researchers stress that while these medications are effective tools for shedding pounds, they are not a magic solution and long-term success likely depends on integrated lifestyle support.
