Fresh analysis indicates that individuals who stop using new weight-loss injections like semaglutide or tirzepatide tend to recover lost weight at a significantly accelerated pace than those who end conventional lifestyle programs.
Findings released in a prominent medical journal demonstrates that while overweight people can lose a large proportion of their body weight while undergoing treatment, the mass is regained at an estimated rate of 0.8 kg per month after stopping.
"Users purchasing these drugs need to be cognizant of the potential of fast rebound weight gain when the therapy is stopped," cautioned expert Dr. Susan Jebb.
That rate of recovery means a return to pre-treatment weight within about a year and a half.
Weighing Approaches
The study, which reviewed 37 of studies involving thousands of patients, contrasted the results of the injectable medications with conventional dieting.
The team note that people who lose weight through dieting typically see a slower weight regain—perhaps 0.1 kg a month—after stopping.
The Reason for the Quick Rebound
Experts believe the mechanism of the injections is key to understanding the amplified regain.
GLP-1 drugs copy a natural hormone called glucagon-like peptide-1, which controls hunger.
"Sustained high doses of GLP-1 concentrations several times higher than normal could lead to the system to generate a reduced amount of its own natural hormone, and may also diminish sensitivity to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this GLP-1 'fix' leads to hunger is unsuppressed, making overeating much more probable."
A Chronic Condition?
The NHS advise the injections for people with obesity-related medical conditions, accompanied by recommended diet and exercise modifications.
Many experts argue that, due to the significant potential of relapse, the treatment might need to be life-long.
This view is reinforced by drug manufacturers, who note that the results "highlight the chronic character of obesity," similar to managing diseases like diabetes.
User Testimonies
People who have discontinued the jabs explain a powerful return of appetite.
"I experienced a trigger flipping and you become ravenous," described one woman.
This difficulty is compounded if individuals have not developed permanent lifestyle or habit modifications during treatment.
Growing Interest
Figures show that a significant number of adults in the UK have tried these injections in the past year, with demand being substantial.
- Adoption is greater among women compared to men.
- The 40s and 50s age group shows the highest usage rates.
- Many access the drugs through private prescriptions rather than the NHS.
In conclusion, clinicians emphasize that while these medications are potent tools for shedding pounds, they are not a standalone cure and maintained weight loss likely depends on ongoing lifestyle management.
