Fresh analysis suggests that people who discontinue new GLP-1 drugs like semaglutide or tirzepatide tend to recover reduced body mass far faster than those who halt conventional lifestyle regimens.
Findings released in a prominent health publication demonstrates that while obese individuals often shed substantial amounts of their body weight while undergoing treatment, the weight comes back at an average rate of 0.8 kg per month after stopping.
"People using such treatments need to be informed of the potential of quick weight regain when the treatment concludes," cautioned researcher Dr. Susan Jebb.
This pace of regain suggests a return to pre-treatment mass within about a year and a half.
Comparing Approaches
The study, which looked at dozens of trials involving thousands of participants, contrasted the outcomes of GLP-1 agonists with conventional dieting.
Scientists point out that individuals who lose weight through lifestyle changes alone typically see a slower weight regain—approximately 100 grams monthly—once they finish.
Explaining the Rapid Rebound
Nutrition scientists suggest the mechanism of the jabs is key to understanding the accelerated regain.
The injections mimic a body's own chemical called GLP-1, which controls hunger.
"Sustained high doses of the hormone levels far above than normal could lead to the body to produce less of its endogenous hormone, and may also reduce sensitivity to its effects," explained Dr. Adam Collins, a nutrition expert.
"Withdrawal of this hormone supplement means hunger is unsuppressed, making binge eating far more likely."
A Chronic Disease?
Health authorities suggest the jabs for individuals with obesity-related medical conditions, alongside prescribed diet and exercise modifications.
Many experts contend that, given the significant potential of relapse, the treatment should be considered ongoing.
This perspective is echoed by drug manufacturers, who note that the findings "highlight the chronic nature of excess weight," similar to managing diseases like hypertension.
User Accounts
Individuals who have discontinued the medication report a sudden resurgence of hunger.
"I experienced a trigger flipping and you're instantly starving," said a patient.
This difficulty is worsened if individuals have not developed lasting lifestyle or habit changes during therapy.
Significant Interest
Figures show that a significant number of adults in the UK have used weight-loss jabs in the past year, with desire remaining high.
- Use is higher among females than males.
- The middle-aged age group shows the highest level of interest.
- A large proportion access the drugs through private prescriptions rather than the NHS.
In conclusion, experts stress that while GLP-1 drugs are powerful tools for shedding pounds, they are not a permanent fix and lasting health benefits relies on ongoing lifestyle changes.
