New research suggests that individuals who come off popular slimming jabs like semaglutide or tirzepatide may regain reduced body mass far faster than those who stop traditional diet and exercise plans.
Research printed in a leading medical journal demonstrates that while obese people frequently drop about a fifth of their total mass while on the medication, the weight is regained at an average rate of nearly a kilo each month once they quit.
"Users using these medications need to be aware of the potential of rapid rebound weight gain when the medication is stopped," warns expert Dr. Susan Jebb.
That rate of recovery suggests a reversion to original weight within about 18 months.
Weighing Therapies
The study, which looked at dozens of trials involving thousands of patients, compared the outcomes of the injectable medications with older methods.
Researchers point out that individuals who lose weight through diet and exercise typically experience a slower creep back—perhaps 100 grams monthly—once they finish.
Understanding the Rapid Regain
Nutrition scientists suggest the mechanism of the injections explains the amplified rebound.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Artificially providing GLP-1 concentrations several times higher than normal might result in the body to generate a reduced amount of its own natural hormone, and could diminish responsiveness to its actions," explained Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' leads to appetite is unsuppressed, making binge eating far more likely."
A Lifelong Condition?
Health authorities recommend the injections for people with obesity-related health risks, accompanied by prescribed lifestyle changes.
A number of clinicians contend that, due to the high risk of relapse, the treatment might need to be ongoing.
This view is supported by drug manufacturers, who say that the results "highlight the chronic nature of excess weight," similar to managing conditions like high blood pressure.
User Accounts
People who have stopped the jabs report a powerful resurgence of cravings.
"It felt as if a trigger flipping and you become starving," recalled an individual.
This difficulty is worsened if patients have not developed sustainable lifestyle or habit modifications during therapy.
Significant Interest
Recent estimates suggest that millions of people in the UK have tried these injections in the last 12 months, with demand continuing to grow.
- Use is higher among women than men.
- The 40s and 50s age group shows the greatest usage rates.
- Many access the medications through private healthcare rather than the NHS.
In conclusion, clinicians emphasize that while GLP-1 drugs are powerful agents for shedding pounds, they are not a magic cure and long-term success likely depends on combined behavioural management.
