A recent study reveals that people who stop using blockbuster slimming jabs like semaglutide or tirzepatide may regain reduced body mass at a significantly accelerated pace than those who end traditional diet and exercise programs.
Published data in a leading health publication shows that while obese people can lose a large proportion of their total mass while using the jabs, the mass returns at an average rate of nearly a kilo each month after stopping.
"Users buying these drugs should be cognizant of the danger of fast weight regain when the therapy concludes," stated expert Dr. Susan Jebb.
This pace of regain means a reversion to starting weight within about a year and a half.
Comparing Therapies
The study, which examined 37 of trials involving thousands of patients, contrasted the outcomes of the injectable medications with other pills.
Researchers point out that people who lose weight through lifestyle changes alone typically experience a less rapid creep back—around 0.1 kg a month—post-intervention.
Explaining the Quick Rebound
Nutrition scientists suggest the mode of action of the injections is key to understanding the accelerated regain.
GLP-1 drugs mimic a body's own chemical called glucagon-like peptide-1, which moderates feelings of fullness.
"Sustained high doses of GLP-1 levels far above than the body's typical production could lead to the body to generate a reduced amount of its own natural GLP-1, and may also lessen sensitivity to its actions," said Dr. Adam Collins, a dietetics expert.
"Discontinuation of this medication means appetite is unsuppressed, making overeating much more probable."
A Lifelong Disease?
The NHS advise the jabs for people with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
Many experts say that, due to the likelihood of relapse, the therapy might need to be ongoing.
This perspective is supported by drug manufacturers, who note that the findings "highlight the persistent nature of excess weight," similar to managing diseases like diabetes.
Patient Accounts
Individuals who have stopped the jabs explain a powerful return of cravings.
"It was like a trigger flipping and you become starving," said one woman.
This difficulty is worsened if users have not developed permanent dietary or behavioural changes during therapy.
Significant Use
Survey data show that a significant number of adults in the UK have tried weight-loss jabs in the past year, with demand being substantial.
- Use is more common among females than men.
- The 40s and 50s age group shows the highest usage rates.
- Many access the medications through private prescriptions rather than the NHS.
In conclusion, clinicians stress that while these medications are powerful tools for shedding pounds, they are not a permanent fix and lasting health benefits relies on ongoing lifestyle changes.
