Fresh analysis reveals that patients who discontinue new slimming jabs like semaglutide or tirzepatide may regain shed pounds much more quickly than those who stop conventional diet and exercise regimens.
Findings released in a major health publication shows that while overweight individuals frequently drop about a fifth of their total mass while undergoing treatment, the weight returns at an estimated rate of nearly a kilo each month after stopping.
"People using these treatments should be cognizant of the danger of rapid rebound weight gain when the treatment ends," cautioned expert Dr. Susan Jebb.
Such speed of recovery means a reversion to original weight in about 18 months.
Analyzing Therapies
The study, which reviewed dozens of studies involving thousands of participants, compared the effects of these new drugs with other pills.
Researchers point out that people who lose weight through lifestyle changes alone generally see a more gradual weight regain—approximately 0.1 kg a month—after stopping.
The Reason for the Fast Rebound
Nutrition scientists propose the way of the drugs explains the heightened weight return.
The injections copy a body's own chemical called glucagon-like peptide-1, which controls hunger.
"Artificially providing GLP-1 levels 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 responsiveness to its effects," explained Dr. Adam Collins, a dietetics expert.
"Stopping of this hormone supplement means hunger is unsuppressed, making excessive eating a significant risk."
A Lifelong Condition?
Health authorities advise the jabs for individuals with weight-linked medical conditions, alongside prescribed lifestyle changes.
Many experts argue that, given the high risk of weight regain, the therapy should be considered ongoing.
This perspective is echoed by drug manufacturers, who say that the findings "underscore the long-term nature of excess weight," akin to managing conditions like hypertension.
Patient Accounts
People who have come off the medication describe a intense resurgence of cravings.
"It was like a switch flipping and you're instantly extremely hungry," described a patient.
This challenge is exacerbated if users have not developed permanent lifestyle or habit changes during therapy.
Growing Adoption
Recent estimates show that millions of people in the UK have used these injections in the past year, with desire being substantial.
- Adoption is more common among females than men.
- The middle-aged demographic shows the highest usage rates.
- A large proportion obtain the drugs through private healthcare rather than public health services.
Finally, experts caution that while the jabs are powerful tools for weight loss, they are not a magic cure and long-term success likely depends on ongoing behavioural changes.
