A recent study reveals that people who discontinue popular slimming jabs like semaglutide or tirzepatide tend to recover shed pounds at a significantly accelerated pace than those who halt traditional lifestyle regimens.
Published data in a prominent medical journal shows that while overweight people often shed a large proportion of their body weight while on the medication, the mass is regained at an average rate of 0.8 kg per month upon discontinuation.
"Individuals purchasing these medications should be aware of the potential of rapid rebound weight gain when the medication ends," warns expert Dr. Susan Jebb.
This pace of regain suggests a return to starting mass within about a year and a half.
Analyzing Therapies
The study, which reviewed 37 of trials involving over 9,000 of patients, compared the results of the injectable medications with other pills.
The team note that people who lose weight through diet and exercise typically see a more gradual weight regain—perhaps 0.1 kg a month—post-intervention.
Understanding the Fast Regain
Doctors suggest the mechanism of the injections accounts for the heightened regain.
GLP-1 drugs imitate a body's own chemical called GLP-1, which moderates hunger.
"Artificially providing GLP-1 concentrations several times higher than the body's typical production could lead to the body to generate a reduced amount of its endogenous GLP-1, and could diminish sensitivity to its actions," noted Dr. Adam Collins, a nutrition specialist.
"Stopping of this GLP-1 'fix' means appetite is unsuppressed, making overeating far more likely."
A Lifelong Disease?
Medical guidelines recommend the injections for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Professionals contend that, given the likelihood of weight regain, the therapy might need to be long-term.
This perspective is echoed by pharmaceutical companies, who state that the results "underscore the persistent nature of obesity," similar to managing diseases like hypertension.
Patient Experiences
Individuals who have stopped the medication explain a sudden resurgence of hunger.
"It was like something that goes on and you become extremely hungry," said an individual.
This challenge is exacerbated if patients have not developed permanent lifestyle or habit modifications during treatment.
Growing Interest
Figures suggest that millions of adults in the UK have tried weight-loss jabs in the last 12 months, with interest remaining high.
- Use is more common among females than males.
- The middle-aged age group shows the highest usage rates.
- Many obtain the medications through private prescriptions rather than public health services.
Finally, researchers emphasize that while the jabs are potent tools for shedding pounds, they are not a standalone cure and long-term success likely depends on integrated lifestyle support.
