Fresh analysis suggests that individuals who stop using new weight-loss injections like semaglutide or tirzepatide may regain lost weight far faster than those who end traditional diet and exercise plans.
Published data in a major health publication demonstrates that while overweight people can lose a large proportion of their total mass while on the medication, the mass comes back at an average rate of nearly a kilo each month after stopping.
"Users purchasing such drugs should be aware of the danger of rapid weight regain when the therapy is stopped," stated expert Dr. Susan Jebb.
This pace of regain implies a reversion to starting mass within about one and a half years.
Analyzing Approaches
The study, which reviewed dozens of studies involving over 9,000 of participants, contrasted the effects of the injectable medications with conventional dieting.
The team note that people who lose weight through diet and exercise generally have a more gradual creep back—around 100 grams monthly—once they finish.
Understanding the Fast Regain
Experts believe the mode of action of the jabs accounts for the amplified rebound.
GLP-1 drugs copy a body's own chemical called GLP-1, which controls hunger.
"Artificially providing GLP-1 concentrations far above than normal may cause the system to produce less of its own natural GLP-1, and could diminish sensitivity to its actions," said Dr. Adam Collins, a dietetics specialist.
"Withdrawal of this hormone supplement leads to appetite is uncontrolled, making overeating much more probable."
An Ongoing Disease?
The NHS suggest the injections for people with weight-linked medical conditions, alongside recommended diet and exercise modifications.
Many experts argue that, given the significant potential of relapse, the treatment might need to be ongoing.
This perspective is reinforced by pharmaceutical companies, who say that the findings "underscore the long-term nature of excess weight," similar to managing conditions like diabetes.
User Experiences
Individuals who have stopped the jabs explain a intense resurgence of hunger.
"I experienced a switch flipping and I was suddenly starving," described a patient.
The struggle is worsened if users have not established lasting lifestyle or habit changes during treatment.
Growing Adoption
Survey data show that millions of people in the UK have tried these injections in the last 12 months, with interest remaining high.
- Use is more common among females compared to males.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion obtain the medications through private prescriptions rather than public health services.
In conclusion, clinicians emphasize that while the jabs are powerful agents for weight loss, they are not a magic cure and lasting health benefits hinges on ongoing lifestyle support.
