New research reveals that people who stop using blockbuster slimming jabs like semaglutide or tirzepatide tend to recover lost weight at a significantly accelerated pace than those who halt traditional diet and exercise regimens.
Research printed in a prominent medical journal demonstrates that while obese individuals can lose substantial amounts of their body weight while undergoing treatment, the weight is regained at an average rate of nearly a kilo each month upon discontinuation.
"People buying these treatments should be informed of the danger of rapid weight regain when the medication concludes," warns expert Dr. Susan Jebb.
Such speed of regain implies a return to original mass in about one and a half years.
Weighing Treatments
The analysis, which looked at dozens of trials involving thousands of participants, contrasted the effects of the injectable medications with conventional dieting.
Scientists point out that individuals who lose weight through dieting typically see a less rapid weight regain—perhaps 100 grams monthly—once they finish.
The Reason for the Rapid Regain
Experts propose the mechanism of the injections is key to understanding the accelerated weight return.
These medications mimic a body's own chemical called GLP-1, which moderates hunger.
"Long-term administration of the hormone levels several times higher than normal could lead to the system to generate a reduced amount of its own natural GLP-1, and may also reduce responsiveness to its actions," noted Dr. Adam Collins, a nutrition researcher.
"Withdrawal of this hormone supplement means appetite is no longer kept in check, making overeating far more likely."
A Chronic Disease?
Medical guidelines recommend the jabs for people with obesity-related health risks, alongside recommended lifestyle changes.
A number of clinicians contend that, due to the high risk of weight regain, the therapy should be considered long-term.
This perspective is supported by drug manufacturers, who note that the results "underscore the chronic character of excess weight," comparing it to managing diseases like high blood pressure.
Patient Accounts
Individuals who have stopped the jabs describe a sudden return of appetite.
"It felt as if a switch that goes on and you're instantly extremely hungry," described a patient.
This difficulty is compounded if users have not established permanent lifestyle or habit changes during treatment.
Widespread Interest
Survey data suggest that a significant number of adults in the UK have tried weight-loss jabs in the past year, with interest being substantial.
- Use is greater among women than men.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the drugs through private prescriptions rather than public health services.
In conclusion, experts stress that while GLP-1 drugs are effective agents for shedding pounds, they are not a magic fix and lasting health benefits hinges on ongoing lifestyle support.
