A recent study reveals that people who stop using new slimming jabs like semaglutide or tirzepatide can put back on lost weight at a significantly accelerated pace than those who halt traditional lifestyle programs.
Published data in a major health publication demonstrates that while overweight individuals frequently drop substantial amounts of their total mass while undergoing treatment, the weight is regained at an estimated rate of 0.8 kg per month once they quit.
"People using such medications need to be aware of the potential of rapid rebound weight gain when the medication ends," cautioned researcher Dr. Susan Jebb.
This pace of recovery means a return to starting mass within about a year and a half.
Analyzing Approaches
The study, which reviewed 37 of trials involving over 9,000 of participants, contrasted the outcomes of GLP-1 agonists with older methods.
Scientists emphasize that individuals who lose weight through diet and exercise usually have a slower weight regain—around 0.1 kg a month—post-intervention.
The Reason for the Fast Rebound
Experts suggest the mode of action of the injections explains the amplified regain.
GLP-1 drugs copy a body's own chemical called glucagon-like peptide-1, which helps regulate hunger.
"Sustained high doses of the hormone levels several times higher than the body's typical production could lead to the body to produce less of its endogenous hormone, and could reduce sensitivity to its actions," said Dr. Adam Collins, a dietetics expert.
"Withdrawal of this hormone supplement leads to hunger is unsuppressed, making excessive eating much more probable."
An Ongoing Issue?
Medical guidelines recommend the jabs for individuals with obesity-related medical conditions, accompanied by recommended lifestyle changes.
Professionals contend that, due to the high risk of weight regain, the treatment is often life-long.
This opinion is echoed by drug manufacturers, who say that the results "highlight the long-term nature of obesity," similar to managing diseases like hypertension.
Patient Testimonies
Users who have come off the medication describe a intense resurgence of cravings.
"It felt as if a switch flipping and you become extremely hungry," described a patient.
This difficulty is exacerbated if individuals have not developed permanent lifestyle or habit modifications during treatment.
Growing Interest
Survey data show that millions of people in the UK have used weight-loss jabs in the past year, with desire being substantial.
- Use is more common among women than males.
- The 40s and 50s demographic shows the greatest usage rates.
- Many obtain the drugs through private prescriptions rather than the NHS.
Ultimately, experts stress that while GLP-1 drugs are effective tools for weight loss, they are not a standalone fix and long-term success relies on integrated behavioural changes.
