Fresh analysis suggests that individuals who discontinue popular GLP-1 drugs like semaglutide or tirzepatide may regain reduced body mass far faster than those who stop traditional lifestyle programs.
Findings released in a prominent health publication demonstrates that while overweight people can lose about a fifth of their body weight while on the medication, the mass comes back at an average rate of nearly a kilo each month upon discontinuation.
"Users purchasing such treatments need to be cognizant of the risk of fast weight regain when the treatment concludes," stated lead investigator Dr. Susan Jebb.
This pace of regain means a reversion to pre-treatment weight in about a year and a half.
Weighing Approaches
The research, which reviewed dozens of studies involving thousands of patients, contrasted the results of the injectable medications with conventional dieting.
Scientists point out that individuals who shed pounds through dieting generally experience a less rapid creep back—around 100 grams monthly—once they finish.
Understanding the Fast Regain
Experts propose the mechanism of the injections explains the amplified rebound.
The injections copy a body's own chemical called glucagon-like peptide-1, which helps regulate appetite.
"Long-term administration of GLP-1 concentrations several times higher than normal may cause the body to generate a reduced amount of its endogenous hormone, and may also lessen responsiveness to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this medication leads to appetite is uncontrolled, making overeating a significant risk."
A Chronic Disease?
Health authorities advise the injections for people with obesity-related medical conditions, accompanied by prescribed diet and exercise modifications.
Many experts contend that, given the significant potential of relapse, the treatment should be considered ongoing.
This view is reinforced by pharmaceutical companies, who say that the findings "emphasize the chronic nature of excess weight," akin to managing conditions like diabetes.
Patient Experiences
Individuals who have come off the medication describe a sudden resurgence of hunger.
"It was like a switch flipping and you're instantly extremely hungry," said an individual.
This difficulty is exacerbated if users have not developed sustainable lifestyle or habit changes during treatment.
Growing Use
Recent estimates show that millions of people in the UK have tried these injections in the last 12 months, with demand continuing to grow.
- Adoption is higher among women than men.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion access the drugs through private prescriptions rather than public health services.
In conclusion, clinicians stress that while the jabs are effective agents for shedding pounds, they are not a permanent solution and long-term success hinges on integrated lifestyle management.
