Fresh analysis reveals that individuals who discontinue popular weight-loss injections like semaglutide or tirzepatide can put back on lost weight much more quickly than those who end traditional diet and exercise regimens.
Findings released in a leading medical journal points out that while overweight people can lose about a fifth of their body weight while using the jabs, the mass is regained at an estimated rate of 0.8 kg per month once they quit.
"Users purchasing these treatments must be cognizant of the risk of rapid rebound weight gain when the treatment ends," stated researcher Dr. Susan Jebb.
This pace of regain means a reversion to original mass within about a year and a half.
Analyzing Treatments
The study, which examined 37 of studies involving over 9,000 of participants, compared the results of the injectable medications with conventional dieting.
The team note that people who shed pounds through dieting generally see a slower weight regain—approximately 0.1 kg a month—post-intervention.
Explaining the Quick Rebound
Doctors believe the way of the injections is key to understanding the amplified regain.
These medications mimic a natural hormone called glucagon-like peptide-1, which moderates feelings of fullness.
"Artificially providing GLP-1 levels several times higher than the body's typical production might result in the body to generate a reduced amount of its endogenous hormone, and may also diminish responsiveness to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this hormone supplement means appetite is no longer kept in check, making binge eating a significant risk."
A Chronic Condition?
The NHS advise the injections for people with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals contend that, considering the likelihood of weight regain, the therapy should be considered long-term.
This opinion is supported by pharmaceutical companies, who state that the results "highlight the persistent nature of obesity," similar to managing conditions like hypertension.
User Experiences
People who have come off the medication describe a powerful return of cravings.
"It was like a trigger that goes on and you become starving," described one woman.
This challenge is worsened if users have not developed sustainable lifestyle or habit modifications during therapy.
Widespread Interest
Figures suggest that a significant number of people in the UK have used weight-loss jabs in the past year, with desire being substantial.
- Adoption is more common among women than men.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion access the drugs through private healthcare rather than public health services.
Ultimately, researchers stress that while GLP-1 drugs are potent agents for weight loss, they are not a magic solution and lasting health benefits relies on integrated lifestyle changes.
