A recent study suggests that patients who discontinue new weight-loss injections like semaglutide or tirzepatide may regain reduced body mass at a significantly accelerated pace than those who end traditional diet and exercise programs.
Published data in a prominent medical journal shows that while obese people frequently drop substantial amounts of their body weight while using the jabs, the weight is regained at an estimated rate of nearly a kilo each month once they quit.
"Users buying these medications should be cognizant of the risk of fast weight regain when the medication ends," warns expert Dr. Susan Jebb.
Such speed of regain suggests a reversion to original weight within about 18 months.
Weighing Therapies
The research, which examined dozens of trials involving thousands of participants, compared the results of the injectable medications with other pills.
Scientists point out that people who shed pounds through diet and exercise usually see a slower weight regain—approximately 0.1 kg a month—after stopping.
Understanding the Rapid Rebound
Nutrition scientists suggest the mode of action of the jabs explains the accelerated rebound.
The injections mimic a body's own chemical called GLP-1, which controls hunger.
"Artificially providing the hormone concentrations far above than the body's typical production might result in the body to produce less of its endogenous hormone, and may also diminish sensitivity to its effects," explained Dr. Adam Collins, a nutrition specialist.
"Stopping of this GLP-1 'fix' leads to appetite is unsuppressed, making excessive eating much more probable."
A Chronic Condition?
Medical guidelines recommend the jabs for individuals with obesity-related health risks, alongside prescribed diet and exercise modifications.
A number of clinicians contend that, considering the likelihood of relapse, the treatment is often ongoing.
This opinion is supported by pharmaceutical companies, who note that the results "underscore the chronic nature of excess weight," comparing it to managing diseases like diabetes.
Patient Testimonies
Individuals who have discontinued the jabs explain a intense resurgence of appetite.
"I experienced a trigger that goes on and you're instantly ravenous," recalled one woman.
This challenge is exacerbated if users have not developed sustainable lifestyle or habit changes during therapy.
Significant Use
Recent estimates show that a significant number of people in the UK have used weight-loss jabs in the last 12 months, with interest being substantial.
- Use is more common among females than men.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion access the drugs through private prescriptions rather than the NHS.
Ultimately, experts stress that while these medications are powerful agents for shedding pounds, they are not a permanent cure and lasting health benefits relies on combined behavioural support.
