Fresh analysis reveals that individuals who come off popular slimming jabs like semaglutide or tirzepatide tend to recover reduced body mass far faster than those who end conventional lifestyle regimens.
Findings released in a major medical journal shows that while obese people frequently drop substantial amounts of their total mass while undergoing treatment, the weight returns at an average rate of nearly a kilo each month upon discontinuation.
"Users using such drugs should be cognizant of the danger of quick weight regain when the medication concludes," cautioned expert Dr. Susan Jebb.
This pace of regain implies a return to pre-treatment mass in about 18 months.
Comparing Therapies
The research, which looked at dozens of studies involving over 9,000 of patients, compared the effects of the injectable medications with conventional dieting.
Researchers point out that people who shed pounds through dieting typically have a more gradual weight regain—approximately 0.1 kg a month—post-intervention.
Explaining the Quick Regain
Experts propose the mechanism of the drugs explains the accelerated regain.
The injections mimic a body's own chemical called GLP-1, which controls hunger.
"Sustained high doses of the hormone levels far above than normal may cause the body to produce less of its endogenous GLP-1, and may also lessen sensitivity to its effects," explained Dr. Adam Collins, a dietetics specialist.
"Stopping of this hormone supplement leads to hunger is uncontrolled, making binge eating a significant risk."
A Lifelong Disease?
The NHS advise the injections for people with weight-linked medical conditions, alongside recommended diet and exercise modifications.
Many experts contend that, due to the high risk of relapse, the therapy is often ongoing.
This opinion is reinforced by drug manufacturers, who say that the findings "highlight the chronic nature of obesity," comparing it to managing diseases like diabetes.
Patient Testimonies
Users who have come off the medication explain a powerful return of hunger.
"It felt as if something that goes on and you become starving," recalled one woman.
This difficulty is worsened if individuals have not adopted sustainable dietary or behavioural changes during treatment.
Growing Adoption
Survey data suggest that millions of people in the UK have tried weight-loss jabs in the past year, with interest remaining high.
- Use is more common among women than males.
- The middle-aged age group shows the greatest usage rates.
- Many access the medications through private prescriptions rather than the NHS.
Finally, researchers stress that while the jabs are effective tools for weight loss, they are not a magic solution and long-term success relies on combined behavioural support.
