A recent study indicates that individuals who discontinue blockbuster weight-loss injections like semaglutide or tirzepatide can put back on reduced body mass at a significantly accelerated pace than those who stop traditional diet and exercise plans.
Findings released in a prominent health publication demonstrates that while overweight individuals can lose about a fifth of their body weight while on the medication, the weight returns at an average rate of nearly a kilo each month after stopping.
"Users using such drugs need to be aware of the potential of rapid rebound weight gain when the medication is stopped," warns researcher Dr. Susan Jebb.
This pace of regain implies a reversion to original weight within about 18 months.
Analyzing Treatments
The analysis, which examined dozens of studies involving thousands of participants, compared the results of the injectable medications with other pills.
Researchers note that individuals who lose weight through diet and exercise generally see a more gradual creep back—perhaps 100 grams monthly—post-intervention.
The Reason for the Quick Regain
Doctors suggest the way of the drugs is key to understanding the accelerated weight return.
These medications copy a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Long-term administration of GLP-1 concentrations far above than the body's typical production might result in the system to produce less of its endogenous GLP-1, and could lessen responsiveness to its actions," explained Dr. Adam Collins, a dietetics expert.
"Withdrawal of this GLP-1 'fix' means appetite is no longer kept in check, making overeating much more probable."
A Chronic Disease?
The NHS advise the injections for individuals with weight-linked health risks, alongside prescribed lifestyle changes.
A number of clinicians contend that, due to the significant potential of weight regain, the treatment is often long-term.
This opinion is supported by drug manufacturers, who say that the findings "underscore the persistent character of obesity," similar to managing diseases like diabetes.
Patient Experiences
People who have discontinued the jabs describe a sudden return of hunger.
"I experienced a switch flipping and I was suddenly ravenous," recalled a patient.
This challenge is exacerbated if patients have not established lasting lifestyle or habit changes during therapy.
Growing Interest
Recent estimates suggest that millions of people in the UK have used weight-loss jabs in the last 12 months, with interest remaining high.
- Use is greater among females compared to males.
- The middle-aged demographic shows the greatest level of interest.
- A large proportion obtain the drugs through private healthcare rather than the NHS.
In conclusion, experts caution that while the jabs are potent agents for weight loss, they are not a standalone solution and lasting health benefits likely depends on ongoing lifestyle support.
