A recent study suggests that patients who come off blockbuster slimming jabs like semaglutide or tirzepatide tend to recover shed pounds at a significantly accelerated pace than those who end conventional diet and exercise programs.
Published data in a major medical journal shows that while obese people can lose substantial amounts of their total mass while using the jabs, the mass comes back at an average rate of 0.8 kg per month upon discontinuation.
"People purchasing such treatments should be cognizant of the risk of quick rebound weight gain when the medication ends," warns lead investigator Dr. Susan Jebb.
Such speed of recovery suggests a return to original mass in about a year and a half.
Comparing Therapies
The analysis, which reviewed 37 of studies involving over 9,000 of patients, compared the outcomes of GLP-1 agonists with older methods.
Researchers point out that individuals who shed pounds through dieting usually see a slower creep back—approximately 0.1 kg a month—once they finish.
Explaining the Quick Regain
Doctors believe the mode of action of the jabs accounts for the accelerated weight return.
GLP-1 drugs imitate a natural hormone called GLP-1, which moderates hunger.
"Artificially providing the hormone concentrations several times higher than the body's typical production may cause the system to produce less of its endogenous hormone, and could reduce sensitivity to its effects," explained Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this hormone supplement results in appetite is uncontrolled, making excessive eating far more likely."
A Chronic Disease?
Medical guidelines recommend the injections for people with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
Many experts say that, due to the high risk of relapse, the therapy might need to be long-term.
This perspective is reinforced by pharmaceutical companies, who state that the findings "highlight the long-term character of excess weight," similar to managing diseases like high blood pressure.
User Accounts
Individuals who have discontinued the jabs describe a sudden resurgence of hunger.
"It was like something flipping and you're instantly extremely hungry," recalled a patient.
The struggle is exacerbated if users have not adopted sustainable lifestyle or habit modifications during treatment.
Growing Use
Figures suggest that a significant number of adults in the UK have used these injections in the last 12 months, with demand being substantial.
- Adoption is greater among females compared to males.
- The 40s and 50s age group shows the greatest usage rates.
- A large proportion obtain the drugs through private healthcare rather than public health services.
Finally, researchers stress that while these medications are potent agents for shedding pounds, they are not a permanent cure and maintained weight loss hinges on combined lifestyle support.
