A recent study suggests that individuals who come off blockbuster slimming jabs like semaglutide or tirzepatide tend to recover shed pounds at a significantly accelerated pace than those who halt conventional diet and exercise plans.
Research printed in a prominent medical journal shows that while obese people often shed a large proportion of their body weight while on the medication, the weight comes back at an estimated rate of 0.8 kg per month after stopping.
"People purchasing these treatments must be cognizant of the potential of fast rebound weight gain when the treatment concludes," cautioned researcher Dr. Susan Jebb.
Such speed of recovery implies a reversion to starting mass in about one and a half years.
Weighing Approaches
The study, which reviewed 37 of trials involving thousands of patients, contrasted the effects of the injectable medications with conventional dieting.
Researchers note that people who lose weight through diet and exercise usually see a less rapid creep back—around 0.1 kg a month—post-intervention.
Understanding the Quick Regain
Nutrition scientists believe the mode of action of the drugs explains the amplified weight return.
These medications imitate a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Artificially providing GLP-1 levels far above than normal may cause the body to produce less of its endogenous GLP-1, and could lessen sensitivity to its actions," said Dr. Adam Collins, a nutrition expert.
"Withdrawal of this medication leads to appetite is no longer kept in check, making excessive eating a significant risk."
A Chronic Disease?
Health authorities advise the injections for individuals with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
Many experts say that, given the high risk of relapse, the therapy should be considered ongoing.
This opinion is echoed by pharmaceutical companies, who say that the findings "highlight the persistent nature of obesity," akin to managing conditions like hypertension.
User Accounts
People who have come off the medication explain a intense return of cravings.
"It was like a switch flipping and you're instantly extremely hungry," described an individual.
This difficulty is worsened if individuals have not adopted permanent dietary or behavioural changes during treatment.
Significant Adoption
Recent estimates indicate that millions of people in the UK have tried these injections in the last 12 months, with desire being substantial.
- Use is more common among females compared to men.
- The middle-aged demographic shows the highest usage rates.
- A large proportion access the drugs through private prescriptions rather than the NHS.
Finally, researchers emphasize that while GLP-1 drugs are potent agents for shedding pounds, they are not a magic fix and long-term success relies on combined lifestyle management.
