New research indicates that patients who come off popular weight-loss injections like semaglutide or tirzepatide tend to recover shed pounds much more quickly than those who end traditional diet and exercise programs.
Research printed in a prominent medical journal shows that while overweight individuals can lose a large proportion of their body weight while on the medication, the weight returns at an estimated rate of 0.8 kg per month once they quit.
"Individuals buying these treatments must be aware of the potential of rapid weight regain when the medication ends," warns expert Dr. Susan Jebb.
Such speed of regain suggests a return to pre-treatment weight in about 18 months.
Analyzing Approaches
The study, which examined 37 of trials involving thousands of participants, contrasted the results of GLP-1 agonists with conventional dieting.
Scientists emphasize that people who lose weight through lifestyle changes alone usually see a more gradual weight regain—perhaps 100 grams monthly—after stopping.
Understanding the Quick Rebound
Nutrition scientists believe the mechanism of the injections explains the accelerated regain.
The injections mimic a natural hormone called GLP-1, which controls appetite.
"Artificially providing GLP-1 levels far above than normal might result in the body to produce less of its own natural hormone, and may also lessen sensitivity to its actions," explained Dr. Adam Collins, a nutrition expert.
"Discontinuation of this hormone supplement results in appetite is unsuppressed, making binge eating a significant risk."
An Ongoing Issue?
Medical guidelines advise the injections for people with obesity-related medical conditions, alongside prescribed lifestyle changes.
Professionals contend that, considering the likelihood of weight regain, the therapy is often life-long.
This view is supported by pharmaceutical companies, who say that the findings "highlight the chronic nature of excess weight," similar to managing diseases like hypertension.
Patient Accounts
Individuals who have stopped the jabs explain a intense resurgence of hunger.
"I experienced a switch flipping and you're instantly ravenous," described one woman.
This challenge is compounded if users have not developed lasting dietary or behavioural modifications during treatment.
Growing Adoption
Figures show that millions of adults in the UK have used these injections in the last 12 months, with interest being substantial.
- Use is greater among females than men.
- The middle-aged demographic shows the highest usage rates.
- A large proportion obtain the medications through private healthcare rather than public health services.
In conclusion, experts caution that while these medications are powerful tools for shedding pounds, they are not a permanent cure and lasting health benefits hinges on combined lifestyle support.
