Fresh analysis indicates that people who come off new GLP-1 drugs like semaglutide or tirzepatide can put back on shed pounds far faster than those who stop traditional lifestyle programs.
Published data in a major medical journal points out that while overweight people frequently drop substantial amounts of their total mass while on the medication, the weight comes back at an average rate of 0.8 kg per month upon discontinuation.
"People buying these drugs need to be cognizant of the potential of quick weight regain when the medication ends," stated researcher Dr. Susan Jebb.
Such speed of regain implies a reversion to starting weight within about 18 months.
Weighing Treatments
The study, which looked at 37 of trials involving thousands of participants, contrasted the outcomes of GLP-1 agonists with conventional dieting.
The team note that individuals who lose weight through dieting generally experience a less rapid creep back—approximately 0.1 kg a month—after stopping.
The Reason for the Rapid Regain
Nutrition scientists propose the mechanism of the injections is key to understanding the amplified weight return.
GLP-1 drugs imitate a natural hormone called GLP-1, which moderates hunger.
"Sustained high doses of GLP-1 levels several times higher than normal may cause the body to generate a reduced amount of its endogenous hormone, and could lessen responsiveness to its effects," explained Dr. Adam Collins, a dietetics expert.
"Discontinuation of this medication means appetite is uncontrolled, making excessive eating far more likely."
A Lifelong Condition?
The NHS advise the jabs for individuals with weight-linked health risks, accompanied by prescribed lifestyle changes.
A number of clinicians contend that, due to the likelihood of weight regain, the treatment might need to be life-long.
This perspective is echoed by drug manufacturers, who say that the findings "underscore the persistent character of obesity," comparing it to managing diseases like hypertension.
User Experiences
Users who have discontinued the medication explain a sudden return of cravings.
"I experienced something activating and you're instantly ravenous," recalled an individual.
The struggle is compounded if individuals have not established lasting lifestyle or habit modifications during treatment.
Growing Adoption
Survey data indicate that a significant number of adults in the UK have used weight-loss jabs in the past year, with demand remaining high.
- Adoption is more common among women compared to men.
- The middle-aged age group shows the greatest usage rates.
- Many obtain the medications through private healthcare rather than public health services.
In conclusion, clinicians stress that while GLP-1 drugs are potent agents for shedding pounds, they are not a permanent cure and long-term success hinges on integrated lifestyle changes.
