A recent study reveals that patients who discontinue popular GLP-1 drugs like semaglutide or tirzepatide tend to recover lost weight much more quickly than those who end conventional lifestyle regimens.
Research printed in a major medical journal demonstrates that while overweight individuals frequently drop a large proportion of their body weight while on the medication, the mass comes back at an estimated rate of nearly a kilo each month once they quit.
"Individuals purchasing such treatments must be cognizant of the danger of quick weight regain when the therapy is stopped," stated researcher Dr. Susan Jebb.
Such speed of recovery means a return to original weight in about 18 months.
Weighing Approaches
The research, which examined 37 of trials involving thousands of patients, contrasted the outcomes of these new drugs with other pills.
The team emphasize that people who shed pounds through diet and exercise usually see a less rapid creep back—around 0.1 kg a month—after stopping.
Understanding the Fast Regain
Nutrition scientists believe the mechanism of the injections accounts for the amplified weight return.
GLP-1 drugs mimic a natural hormone called glucagon-like peptide-1, which controls feelings of fullness.
"Artificially providing GLP-1 levels far above than the body's typical production might result in the system to generate a reduced amount of its own natural hormone, and may also lessen sensitivity to its effects," noted Dr. Adam Collins, a dietetics expert.
"Discontinuation of this hormone supplement results in hunger is no longer kept in check, making overeating a significant risk."
An Ongoing Issue?
Medical guidelines advise 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 might need to be long-term.
This view is supported by drug manufacturers, who note that the results "emphasize the chronic character of excess weight," comparing it to managing diseases like hypertension.
User Accounts
People who have come off the jabs report a powerful return of cravings.
"It was like a switch activating and I was suddenly ravenous," described one woman.
This difficulty is exacerbated if users have not adopted lasting dietary or behavioural changes during treatment.
Significant Adoption
Survey data show that a significant number of adults in the UK have used these injections in the past year, with desire continuing to grow.
- Use is higher among females than males.
- The middle-aged age group shows the greatest usage rates.
- A large proportion obtain the medications through private prescriptions rather than public health services.
Ultimately, researchers stress that while the jabs are potent tools for weight loss, they are not a magic fix and long-term success hinges on ongoing lifestyle changes.
