New research indicates that patients who discontinue popular slimming jabs like semaglutide or tirzepatide can put back on reduced body mass far faster than those who halt traditional lifestyle regimens.
Published data in a leading medical journal shows that while overweight individuals can lose substantial amounts of their body weight while on the medication, the mass is regained at an estimated rate of nearly a kilo each month once they quit.
"Users using these drugs need to be cognizant of the risk of quick weight regain when the medication is stopped," stated lead investigator Dr. Susan Jebb.
That rate of regain implies a return to pre-treatment mass in about a year and a half.
Analyzing Approaches
The analysis, which examined dozens of trials involving thousands of participants, contrasted the results of the injectable medications with conventional dieting.
The team emphasize that individuals who shed pounds through lifestyle changes alone generally have a more gradual creep back—approximately 0.1 kg a month—after stopping.
Understanding the Fast Regain
Nutrition scientists propose the mode of action of the injections accounts for the amplified regain.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Long-term administration of GLP-1 concentrations far above than normal might result in the body to generate a reduced amount of its endogenous hormone, and may also lessen responsiveness to its actions," said Dr. Adam Collins, a dietetics expert.
"Withdrawal of this medication leads to appetite is no longer kept in check, making overeating much more probable."
An Ongoing Disease?
The NHS recommend the injections for people with weight-linked health risks, alongside recommended lifestyle changes.
A number of clinicians say that, given the high risk of weight regain, the treatment is often ongoing.
This perspective is supported by pharmaceutical companies, who state that the findings "underscore the chronic character of excess weight," comparing it to managing diseases like diabetes.
User Testimonies
Users who have come off the jabs describe a powerful resurgence of cravings.
"It was like something that goes on and you become extremely hungry," recalled a patient.
This difficulty is compounded if users have not developed permanent lifestyle or habit modifications during treatment.
Growing Interest
Recent estimates indicate that millions of people in the UK have tried weight-loss jabs in the last 12 months, with desire remaining high.
- Use is more common among females than men.
- The middle-aged age group shows the highest usage rates.
- A large proportion access the medications through private prescriptions rather than the NHS.
Ultimately, clinicians caution that while these medications are effective agents for shedding pounds, they are not a permanent cure and lasting health benefits relies on combined lifestyle support.
