New research indicates that individuals who discontinue popular weight-loss injections like semaglutide or tirzepatide tend to recover reduced body mass far faster than those who halt traditional diet and exercise programs.
Findings released in a prominent medical journal points out that while overweight individuals often shed substantial amounts of their body weight while undergoing treatment, the weight is regained at an estimated rate of nearly a kilo each month after stopping.
"People using such treatments should be cognizant of the risk of fast weight regain when the therapy ends," stated lead investigator Dr. Susan Jebb.
Such speed of recovery suggests a reversion to starting weight in about one and a half years.
Analyzing Treatments
The research, which reviewed 37 of studies involving thousands of patients, contrasted the results of GLP-1 agonists with older methods.
Scientists emphasize that individuals who lose weight through dieting generally experience a more gradual creep back—around 100 grams monthly—after stopping.
Understanding the Fast Regain
Doctors suggest the mode of action of the injections is key to understanding the amplified weight return.
These medications imitate a body's own chemical called GLP-1, which moderates appetite.
"Sustained high doses of GLP-1 concentrations far above than normal could lead to the system to generate a reduced amount of its own natural GLP-1, and may also reduce sensitivity to its effects," said Dr. Adam Collins, a nutrition expert.
"Stopping of this hormone supplement leads to hunger is no longer kept in check, making excessive eating much more probable."
An Ongoing Issue?
Medical guidelines recommend the jabs for individuals with obesity-related health risks, accompanied by prescribed diet and exercise modifications.
Many experts say that, given the high risk of weight regain, the treatment might need to be ongoing.
This view is echoed by pharmaceutical companies, who state that the results "emphasize the long-term nature of excess weight," comparing it to managing conditions like high blood pressure.
User Accounts
Individuals who have come off the medication describe a sudden return of cravings.
"I experienced a switch flipping and I was suddenly ravenous," described an individual.
This challenge is worsened if individuals have not established lasting dietary or behavioural modifications during treatment.
Significant Use
Survey data indicate that a significant number of people in the UK have tried these injections in the last 12 months, with desire continuing to grow.
- Use is higher among women than men.
- The 40s and 50s age group shows the highest level of interest.
- Many obtain the medications through private healthcare rather than the NHS.
In conclusion, researchers caution that while the jabs are powerful tools for shedding pounds, they are not a magic solution and lasting health benefits hinges on combined behavioural changes.
