New research suggests that individuals who come off popular slimming jabs like semaglutide or tirzepatide tend to recover reduced body mass at a significantly accelerated pace than those who end conventional lifestyle regimens.
Findings released in a leading medical journal shows that while obese individuals can lose about a fifth of their body weight while undergoing treatment, the weight returns at an estimated rate of 0.8 kg per month after stopping.
"Users buying such medications should be cognizant of the danger of rapid rebound weight gain when the treatment ends," stated researcher Dr. Susan Jebb.
Such speed of recovery suggests a return to pre-treatment weight in about 18 months.
Comparing Therapies
The analysis, which examined dozens of studies involving over 9,000 of participants, contrasted the outcomes of these new drugs with other pills.
Researchers emphasize that people who lose weight through dieting typically have a more gradual creep back—around 100 grams monthly—post-intervention.
The Reason for the Quick Rebound
Doctors believe the mode of action of the injections explains the heightened weight return.
GLP-1 drugs imitate a natural hormone called glucagon-like peptide-1, which helps regulate appetite.
"Sustained high doses of the hormone concentrations far above than the body's typical production could lead to the system to generate a reduced amount of its own natural hormone, and could reduce sensitivity to its effects," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement means appetite is no longer kept in check, making binge eating much more probable."
A Lifelong Disease?
The NHS recommend the jabs for individuals with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
A number of clinicians argue that, considering the likelihood of relapse, the treatment should be considered long-term.
This perspective is supported by drug manufacturers, who note that the results "emphasize the long-term nature of obesity," similar to managing conditions like hypertension.
Patient Accounts
Individuals who have come off the jabs describe a intense resurgence of hunger.
"It was like a switch activating and you're instantly extremely hungry," described an individual.
The struggle is worsened if users have not developed lasting lifestyle or habit changes during treatment.
Widespread Adoption
Recent estimates suggest that millions of people in the UK have tried these injections in the last 12 months, with interest continuing to grow.
- Adoption is higher among females compared to males.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion access the drugs through private prescriptions rather than public health services.
In conclusion, experts emphasize that while the jabs are potent agents for shedding pounds, they are not a standalone cure and maintained weight loss hinges on integrated lifestyle support.
