Fresh analysis indicates that individuals who stop using blockbuster slimming jabs like semaglutide or tirzepatide may regain lost weight at a significantly accelerated pace than those who stop traditional diet and exercise regimens.
Published data in a leading health publication shows that while obese people can lose substantial amounts of their total mass while on the medication, the weight is regained at an estimated rate of nearly a kilo each month once they quit.
"Users purchasing these drugs should be aware of the potential of rapid rebound weight gain when the therapy ends," stated researcher Dr. Susan Jebb.
This pace of regain suggests a reversion to pre-treatment mass in about a year and a half.
Weighing Approaches
The study, which reviewed 37 of trials involving over 9,000 of participants, compared the effects of the injectable medications with other pills.
Scientists emphasize that individuals who shed pounds through dieting usually have a less rapid creep back—approximately 100 grams monthly—once they finish.
Explaining the Fast Rebound
Experts propose the mode of action of the jabs explains the amplified weight return.
The injections copy a natural hormone called glucagon-like peptide-1, which moderates hunger.
"Artificially providing the hormone concentrations several times higher than the body's typical production could lead to the system to generate a reduced amount of its own natural GLP-1, and could lessen sensitivity to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this hormone supplement leads to hunger is uncontrolled, making excessive eating far more likely."
A Chronic Condition?
The NHS suggest the injections for people with weight-linked health risks, accompanied by prescribed lifestyle changes.
Professionals argue that, due to the high risk of relapse, the therapy should be considered ongoing.
This perspective is reinforced by pharmaceutical companies, who say that the findings "underscore the long-term nature of obesity," comparing it to managing diseases like high blood pressure.
User Testimonies
People who have stopped the jabs explain a sudden resurgence of cravings.
"It was like something flipping and you're instantly extremely hungry," described an individual.
This difficulty is exacerbated if patients have not adopted lasting dietary or behavioural modifications during treatment.
Growing Interest
Survey data suggest that millions of people in the UK have tried these injections in the last 12 months, with interest being substantial.
- Adoption is more common among women than men.
- The middle-aged age group shows the highest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than the NHS.
Ultimately, researchers caution that while GLP-1 drugs are potent agents for shedding pounds, they are not a magic cure and maintained weight loss relies on ongoing lifestyle management.
