New research indicates that individuals who come off new weight-loss injections like semaglutide or tirzepatide may regain shed pounds much more quickly than those who end traditional diet and exercise regimens.
Research printed in a major health publication demonstrates that while obese individuals can lose about a fifth of their body weight while using the jabs, the weight comes back at an estimated rate of nearly a kilo each month once they quit.
"People using such treatments should be informed of the potential of rapid weight regain when the therapy concludes," warns lead investigator Dr. Susan Jebb.
This pace of regain implies a return to original mass within about one and a half years.
Analyzing Approaches
The analysis, which examined dozens of trials involving thousands of patients, contrasted the results of these new drugs with conventional dieting.
The team point out that individuals who lose weight through diet and exercise usually experience a less rapid creep back—perhaps 0.1 kg a month—post-intervention.
Understanding the Fast Rebound
Experts propose the mode of action of the jabs explains the accelerated weight return.
These medications copy a body's own chemical called glucagon-like peptide-1, which controls feelings of fullness.
"Sustained high doses of GLP-1 levels far above than normal may cause the system to generate a reduced amount of its endogenous hormone, and may also reduce sensitivity to its effects," noted Dr. Adam Collins, a nutrition expert.
"Withdrawal of this GLP-1 'fix' results in hunger is no longer kept in check, making binge eating a significant risk."
A Lifelong Issue?
Health authorities suggest the injections for individuals with obesity-related medical conditions, accompanied by prescribed lifestyle changes.
Many experts contend that, given the likelihood of weight regain, the treatment should be considered long-term.
This view is echoed by drug manufacturers, who say that the results "highlight the persistent character of excess weight," akin to managing conditions like high blood pressure.
Patient Accounts
Individuals who have come off the jabs explain a powerful resurgence of appetite.
"It felt as if a trigger flipping and I was suddenly starving," described a patient.
The struggle is worsened if users have not developed lasting dietary or behavioural modifications during therapy.
Widespread Adoption
Figures indicate that a significant number of people in the UK have used these injections in the last 12 months, with demand being substantial.
- Adoption is greater among females than men.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion access the medications through private healthcare rather than the NHS.
Ultimately, clinicians stress that while the jabs are potent agents for shedding pounds, they are not a magic cure and maintained weight loss relies on integrated lifestyle management.
