New research indicates that patients who come off popular GLP-1 drugs like semaglutide or tirzepatide tend to recover shed pounds at a significantly accelerated pace than those who end traditional diet and exercise plans.
Published data in a leading medical journal demonstrates that while overweight individuals frequently drop about a fifth of their total mass while using the jabs, the mass is regained at an estimated rate of nearly a kilo each month after stopping.
"People purchasing these treatments need to be cognizant of the risk of rapid weight regain when the therapy ends," warns lead investigator Dr. Susan Jebb.
Such speed of regain implies a reversion to pre-treatment weight within about 18 months.
Analyzing Therapies
The analysis, which examined 37 of trials involving thousands of participants, contrasted the results of the injectable medications with older methods.
The team note that individuals who shed pounds through diet and exercise typically have a less rapid weight regain—perhaps 100 grams monthly—post-intervention.
The Reason for the Rapid Rebound
Doctors suggest the way of the drugs accounts for the heightened weight return.
These medications imitate a body's own chemical called glucagon-like peptide-1, which moderates feelings of fullness.
"Sustained high doses of GLP-1 levels several times higher than normal might result in the body to generate a reduced amount of its endogenous hormone, and could reduce responsiveness to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this medication leads to hunger is unsuppressed, making excessive eating far more likely."
A Lifelong Disease?
Health authorities recommend the jabs for individuals with weight-linked medical conditions, alongside recommended lifestyle changes.
Many experts contend that, given the high risk of weight regain, the therapy is often long-term.
This perspective is echoed by drug manufacturers, who note that the results "underscore the chronic nature of excess weight," akin to managing conditions like hypertension.
Patient Testimonies
People who have come off the jabs explain a intense resurgence of hunger.
"It was like a switch activating and you're instantly ravenous," said a patient.
This challenge is worsened if individuals have not adopted lasting dietary or behavioural changes during therapy.
Significant Adoption
Recent estimates indicate that a significant number of people in the UK have tried these injections in the last 12 months, with desire remaining high.
- Adoption is higher among women than males.
- The middle-aged age group shows the greatest usage rates.
- Many access the drugs through private prescriptions rather than public health services.
In conclusion, clinicians caution that while these medications are potent agents for shedding pounds, they are not a standalone cure and lasting health benefits hinges on ongoing behavioural support.
