A recent study suggests that individuals who come off blockbuster weight-loss injections like semaglutide or tirzepatide can put back on lost weight at a significantly accelerated pace than those who end traditional lifestyle plans.
Published data in a major medical journal shows that while obese people often shed a large proportion of their total mass while undergoing treatment, the weight returns at an average rate of 0.8 kg per month once they quit.
"Users purchasing these medications need to be cognizant of the risk of quick weight regain when the therapy is stopped," cautioned expert Dr. Susan Jebb.
This pace of recovery implies a return to pre-treatment weight within about 18 months.
Comparing Treatments
The analysis, which looked at 37 of trials involving thousands of patients, compared the effects of GLP-1 agonists with other pills.
The team point out that individuals who shed pounds through diet and exercise usually see a more gradual weight regain—approximately 0.1 kg a month—once they finish.
The Reason for the Fast Regain
Experts believe the mode of action of the jabs is key to understanding the heightened rebound.
GLP-1 drugs copy a body's own chemical called GLP-1, which controls hunger.
"Sustained high doses of the hormone levels far above than normal may cause the body to produce less of its endogenous hormone, and could lessen sensitivity to its actions," explained Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' means appetite is uncontrolled, making excessive eating a significant risk."
An Ongoing Issue?
Medical guidelines suggest the injections for individuals with weight-linked health risks, alongside recommended diet and exercise modifications.
Many experts argue that, due to the significant potential of weight regain, the treatment is often ongoing.
This opinion is supported by drug manufacturers, who note that the results "highlight the long-term character of excess weight," akin to managing conditions like diabetes.
User Accounts
Users who have discontinued the medication report a sudden return of hunger.
"It felt as if something that goes on and you're instantly ravenous," said a patient.
This challenge is exacerbated if patients have not established permanent lifestyle or habit modifications during treatment.
Growing Adoption
Recent estimates suggest that a significant number of people in the UK have tried these injections in the last 12 months, with desire continuing to grow.
- Use is higher among women than males.
- The middle-aged demographic shows the greatest level of interest.
- Many obtain the drugs through private prescriptions rather than the NHS.
In conclusion, researchers emphasize that while these medications are effective tools for shedding pounds, they are not a magic cure and lasting health benefits hinges on combined lifestyle support.
