Fresh analysis suggests that people who stop using blockbuster slimming jabs like semaglutide or tirzepatide may regain shed pounds far faster than those who halt traditional lifestyle programs.
Findings released in a leading medical journal points out that while overweight people can lose a large proportion of their total mass while using the jabs, the mass is regained at an estimated rate of 0.8 kg per month upon discontinuation.
"Individuals using such treatments must be informed of the risk of rapid rebound weight gain when the treatment is stopped," stated expert Dr. Susan Jebb.
That rate of recovery implies a reversion to pre-treatment weight in about one and a half years.
Comparing Therapies
The study, which reviewed dozens of studies involving thousands of patients, compared the effects of the injectable medications with older methods.
Researchers emphasize that people who shed pounds through dieting generally experience a more gradual weight regain—around 100 grams monthly—post-intervention.
Understanding the Fast Regain
Nutrition scientists believe the way of the drugs is key to understanding the amplified weight return.
The injections copy a natural hormone called glucagon-like peptide-1, which controls hunger.
"Long-term administration of GLP-1 concentrations several times higher than the body's typical production may cause the body to produce less of its own natural GLP-1, and could reduce responsiveness to its actions," explained Dr. Adam Collins, a dietetics specialist.
"Discontinuation of this GLP-1 'fix' leads to appetite is unsuppressed, making overeating far more likely."
An Ongoing Issue?
Health authorities recommend the jabs for people with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
Professionals say that, considering the high risk of weight regain, the treatment might need to be ongoing.
This opinion is supported by drug manufacturers, who state that the results "highlight the chronic nature of excess weight," akin to managing conditions like hypertension.
User Experiences
Individuals who have come off the jabs describe a intense return of cravings.
"I experienced a trigger flipping and you become ravenous," described a patient.
The struggle is exacerbated if patients have not developed sustainable dietary or behavioural modifications during therapy.
Widespread Adoption
Survey data show that a significant number of people in the UK have tried weight-loss jabs in the last 12 months, with interest remaining high.
- Adoption is more common among females than males.
- The 40s and 50s age group shows the highest level of interest.
- Many obtain the drugs through private healthcare rather than public health services.
Finally, clinicians stress that while the jabs are potent tools for shedding pounds, they are not a permanent solution and maintained weight loss relies on combined behavioural support.
