Fresh analysis indicates that people who come off popular GLP-1 drugs like semaglutide or tirzepatide can put back on reduced body mass at a significantly accelerated pace than those who end conventional lifestyle plans.
Research printed in a leading medical journal demonstrates that while obese people can lose about a fifth of their body weight while on the medication, the mass returns at an estimated rate of 0.8 kg per month upon discontinuation.
"Users purchasing such treatments must be aware of the potential of fast rebound weight gain when the treatment is stopped," cautioned expert Dr. Susan Jebb.
This pace of recovery means a return to pre-treatment mass within about 18 months.
Comparing Therapies
The research, which examined 37 of trials involving thousands of participants, compared the outcomes of GLP-1 agonists with older methods.
Scientists point out that people who lose weight through lifestyle changes alone typically have a less rapid creep back—perhaps 100 grams monthly—post-intervention.
Understanding the Quick Regain
Experts suggest the way of the drugs accounts for the accelerated regain.
The injections mimic a body's own chemical called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Long-term administration of the hormone levels far above than the body's typical production may cause the system to produce less of its own natural hormone, and could diminish responsiveness to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Stopping of this hormone supplement leads to hunger is uncontrolled, making excessive eating much more probable."
A Chronic Issue?
The NHS recommend the jabs for people with weight-linked health risks, accompanied by prescribed lifestyle changes.
Many experts argue that, due to the significant potential of relapse, the therapy might need to be ongoing.
This perspective is reinforced by drug manufacturers, who state that the results "highlight the long-term nature of obesity," similar to managing conditions like hypertension.
Patient Experiences
People who have discontinued the medication report a powerful resurgence of cravings.
"I experienced something activating and I was suddenly starving," described one woman.
This difficulty is compounded if users have not adopted sustainable lifestyle or habit changes during treatment.
Significant Adoption
Figures indicate that millions of adults in the UK have tried weight-loss jabs in the past year, with demand continuing to grow.
- Use is greater among women compared to males.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion access the drugs through private prescriptions rather than public health services.
In conclusion, researchers emphasize that while these medications are potent tools for shedding pounds, they are not a standalone solution and maintained weight loss relies on integrated lifestyle management.
