A recent study indicates that individuals who discontinue popular weight-loss injections like Mounjaro or Wegovy can put back on shed pounds at a significantly accelerated pace than those who end conventional diet and exercise programs.
Published data in a major health publication points out that while obese people often shed a large proportion of their body weight while on the medication, the mass returns at an estimated rate of 0.8 kg per month after stopping.
"People using these drugs should be cognizant of the potential of quick weight regain when the treatment ends," warns lead investigator Dr. Susan Jebb.
Such speed of regain suggests a reversion to original mass in about 18 months.
Comparing Treatments
The study, which looked at 37 of trials involving over 9,000 of patients, contrasted the effects of GLP-1 agonists with conventional dieting.
Scientists point out that individuals who lose weight through diet and exercise usually experience a more gradual creep back—around 100 grams monthly—post-intervention.
Understanding the Quick Regain
Experts believe the mode of action of the jabs accounts for the accelerated weight return.
The injections mimic a natural hormone called GLP-1, which moderates feelings of fullness.
"Sustained high doses of GLP-1 levels several times higher than the body's typical production might result in the system to generate a reduced amount of its endogenous GLP-1, and may also diminish responsiveness to its effects," explained Dr. Adam Collins, a nutrition specialist.
"Stopping of this GLP-1 'fix' results in appetite is no longer kept in check, making binge eating a significant risk."
An Ongoing Condition?
The NHS advise the injections for people with obesity-related medical conditions, accompanied by recommended lifestyle changes.
Many experts contend that, due to the likelihood of relapse, the therapy might need to be life-long.
This opinion is reinforced by drug manufacturers, who note that the results "underscore the chronic character of obesity," comparing it to managing diseases like hypertension.
User Experiences
Individuals who have discontinued the jabs explain a powerful return of hunger.
"It felt as if a switch that goes on and I was suddenly ravenous," said one woman.
This challenge is exacerbated if patients have not adopted lasting lifestyle or habit modifications during treatment.
Growing Interest
Survey data show that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with interest being substantial.
- Adoption is more common among women than males.
- The middle-aged age group shows the greatest level of interest.
- Many obtain the drugs through private healthcare rather than the NHS.
Ultimately, clinicians stress that while these medications are potent agents for shedding pounds, they are not a magic solution and maintained weight loss relies on integrated behavioural support.
