A recent study reveals that people who discontinue new GLP-1 drugs like semaglutide or tirzepatide may regain shed pounds far faster than those who halt traditional diet and exercise programs.
Research printed in a prominent health publication demonstrates that while overweight individuals frequently drop a large proportion 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.
"People purchasing these drugs need to be aware of the risk of quick rebound weight gain when the medication ends," cautioned researcher Dr. Susan Jebb.
Such speed of recovery implies a return to original weight in about a year and a half.
Weighing Approaches
The study, which examined 37 of studies involving thousands of patients, contrasted the effects of these new drugs with older methods.
Scientists point out that people who lose weight through lifestyle changes alone usually have a less rapid creep back—around 100 grams monthly—post-intervention.
Understanding the Fast Regain
Doctors suggest the mechanism of the jabs explains the accelerated weight return.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which moderates hunger.
"Artificially providing the hormone concentrations far above than the body's typical production may cause the system to generate a reduced amount of its endogenous GLP-1, and could reduce responsiveness to its actions," said Dr. Adam Collins, a dietetics specialist.
"Stopping of this medication means hunger is uncontrolled, making binge eating much more probable."
A Chronic Condition?
The NHS suggest the injections for people with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
Many experts argue that, due to the likelihood of weight regain, the treatment is often ongoing.
This view is supported by pharmaceutical companies, who say that the findings "emphasize the persistent character of obesity," akin to managing conditions like hypertension.
User Accounts
Users who have come off the medication report a powerful resurgence of cravings.
"It was like a trigger that goes on and I was suddenly ravenous," said one woman.
This difficulty is worsened if individuals have not established sustainable lifestyle or habit changes during therapy.
Growing Adoption
Survey data show that millions of people in the UK have used these injections in the last 12 months, with desire continuing to grow.
- Use is more common among women than males.
- The 40s and 50s age group shows the greatest level of interest.
- A large proportion access the medications through private healthcare rather than the NHS.
Finally, researchers emphasize that while these medications are effective tools for weight loss, they are not a magic solution and maintained weight loss hinges on ongoing behavioural changes.
