New research indicates that individuals who discontinue blockbuster weight-loss injections like Mounjaro or Wegovy tend to recover lost weight far faster than those who end traditional lifestyle regimens.
Published data in a leading medical journal points out that while overweight people often shed about a fifth of their body weight while undergoing treatment, the weight is regained at an estimated rate of 0.8 kg per month upon discontinuation.
"Users using these medications must be informed of the danger of quick weight regain when the treatment is stopped," stated lead investigator Dr. Susan Jebb.
Such speed of recovery implies a reversion to original weight in about one and a half years.
Weighing Therapies
The research, which looked at dozens of trials involving over 9,000 of participants, compared the effects of GLP-1 agonists with other pills.
The team point out that individuals who lose weight through lifestyle changes alone generally have a slower creep back—approximately 100 grams monthly—after stopping.
Explaining the Quick Rebound
Doctors suggest the mechanism of the injections explains the accelerated rebound.
The injections copy a body's own chemical called GLP-1, which moderates feelings of fullness.
"Sustained high doses of the hormone levels far above than the body's typical production may cause the body to produce less of its own natural hormone, and could diminish sensitivity to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this medication leads to appetite is unsuppressed, making binge eating far more likely."
A Lifelong Issue?
Health authorities recommend the jabs for people with weight-linked health risks, accompanied by recommended lifestyle changes.
A number of clinicians contend that, given the likelihood of relapse, the treatment might need to be life-long.
This opinion is echoed by pharmaceutical companies, who note that the findings "emphasize the chronic nature of excess weight," akin to managing conditions like diabetes.
Patient Experiences
Individuals who have discontinued the jabs explain a sudden resurgence of hunger.
"It felt as if a trigger that goes on and you're instantly ravenous," said an individual.
This difficulty is compounded if users have not established lasting lifestyle or habit modifications during treatment.
Significant Interest
Figures show that millions of people in the UK have used weight-loss jabs in the past year, with desire remaining high.
- Adoption is greater among females compared to men.
- The 40s and 50s age group shows the highest level of interest.
- A large proportion access the drugs through private prescriptions rather than public health services.
In conclusion, researchers stress that while these medications are powerful agents for shedding pounds, they are not a magic cure and long-term success relies on ongoing lifestyle management.
