New research suggests that people who stop using popular weight-loss injections like semaglutide or tirzepatide tend to recover shed pounds much more quickly than those who end traditional lifestyle plans.
Research printed in a major health publication demonstrates that while overweight individuals frequently drop a large proportion of their total mass while undergoing treatment, the mass comes back at an average rate of 0.8 kg per month upon discontinuation.
"People purchasing such medications need to be informed of the potential of quick weight regain when the medication concludes," cautioned researcher Dr. Susan Jebb.
Such speed of regain implies a return to pre-treatment mass within about 18 months.
Weighing Treatments
The study, which reviewed 37 of studies involving thousands of participants, compared the effects of these new drugs with older methods.
Researchers note that people who shed pounds through dieting typically see a more gradual creep back—perhaps 0.1 kg a month—post-intervention.
Explaining the Rapid Regain
Nutrition scientists propose the way of the drugs explains the heightened rebound.
GLP-1 drugs mimic a natural hormone called GLP-1, which helps regulate appetite.
"Artificially providing GLP-1 levels far above than the body's typical production may cause the body to produce less of its own natural GLP-1, and may also reduce responsiveness to its actions," said Dr. Adam Collins, a dietetics expert.
"Discontinuation of this medication results in appetite is unsuppressed, making excessive eating a significant risk."
A Chronic Issue?
Health authorities suggest the injections for individuals with obesity-related medical conditions, alongside recommended lifestyle changes.
A number of clinicians say that, considering the likelihood of relapse, the therapy is often life-long.
This opinion is reinforced by drug manufacturers, who state that the results "highlight the persistent nature of obesity," comparing it to managing diseases like hypertension.
Patient Testimonies
People who have stopped the medication explain a sudden resurgence of cravings.
"It felt as if something that goes on and I was suddenly extremely hungry," said an individual.
This challenge is worsened if users have not developed permanent lifestyle or habit modifications during treatment.
Widespread Adoption
Recent estimates show that millions of people in the UK have tried weight-loss jabs in the last 12 months, with desire being substantial.
- Adoption is more common among females than men.
- The middle-aged age group shows the highest level of interest.
- Many access the medications through private prescriptions rather than the NHS.
In conclusion, clinicians stress that while these medications are potent tools for weight loss, they are not a standalone solution and long-term success likely depends on ongoing lifestyle changes.
