A recent study suggests that patients who come off popular slimming jabs like semaglutide or tirzepatide may regain lost weight much more quickly than those who halt traditional lifestyle plans.
Findings released in a leading health publication demonstrates that while overweight individuals often shed substantial amounts of their total mass while undergoing treatment, the mass comes back at an estimated rate of nearly a kilo each month once they quit.
"Individuals using such treatments must be informed of the potential of rapid rebound weight gain when the medication ends," cautioned researcher Dr. Susan Jebb.
Such speed of regain means a reversion to original mass in about one and a half years.
Analyzing Therapies
The research, which looked at dozens of trials involving thousands of participants, compared the results of GLP-1 agonists with conventional dieting.
The team emphasize that individuals who shed pounds through lifestyle changes alone typically see a slower creep back—around 100 grams monthly—after stopping.
Explaining the Rapid Rebound
Doctors propose the mode of action of the drugs explains the amplified regain.
GLP-1 drugs copy a natural hormone called GLP-1, which moderates feelings of fullness.
"Artificially providing GLP-1 concentrations several times higher than the body's typical production may cause the body to generate a reduced amount of its own natural GLP-1, and may also reduce responsiveness to its effects," explained Dr. Adam Collins, a dietetics researcher.
"Stopping of this hormone supplement results in appetite is uncontrolled, making binge eating much more probable."
A Chronic Condition?
Medical guidelines recommend the jabs for people with obesity-related medical conditions, alongside recommended diet and exercise modifications.
Many experts say that, given the likelihood of weight regain, the therapy is often ongoing.
This perspective is reinforced by drug manufacturers, who say that the findings "underscore the persistent character of obesity," akin to managing diseases like diabetes.
User Accounts
Individuals who have stopped the jabs explain a sudden resurgence of cravings.
"It felt as if a trigger activating and I was suddenly extremely hungry," said a patient.
The struggle is exacerbated if patients have not established lasting dietary or behavioural changes during treatment.
Significant Interest
Survey data suggest that a significant number of adults in the UK have tried these injections in the past year, with desire continuing to grow.
- Adoption is higher among females than men.
- The middle-aged age group shows the highest usage rates.
- Many obtain the drugs through private prescriptions rather than public health services.
Ultimately, clinicians emphasize that while the jabs are powerful agents for weight loss, they are not a standalone fix and maintained weight loss relies on integrated lifestyle management.
