New research suggests that patients who discontinue popular weight-loss injections like semaglutide or tirzepatide tend to recover shed pounds much more quickly than those who halt traditional diet and exercise regimens.
Findings released in a major health publication points out that while overweight individuals frequently drop a large proportion of their body weight while using the jabs, the mass comes back at an average rate of 0.8 kg per month after stopping.
"Individuals using such medications need to be informed of the risk of rapid rebound weight gain when the treatment is stopped," cautioned lead investigator Dr. Susan Jebb.
This pace of recovery implies a return to original weight within about one and a half years.
Weighing Approaches
The research, which looked at 37 of trials involving over 9,000 of participants, compared the results of these new drugs with older methods.
Researchers emphasize that people who shed pounds through lifestyle changes alone generally experience a less rapid creep back—approximately 0.1 kg a month—after stopping.
Explaining the Rapid Rebound
Doctors believe the way of the jabs explains the heightened rebound.
The injections imitate a body's own chemical called GLP-1, which moderates feelings of fullness.
"Sustained high doses of the hormone concentrations far above than the body's typical production may cause the body to generate a reduced amount of its own natural GLP-1, and could diminish responsiveness to its effects," said Dr. Adam Collins, a dietetics expert.
"Stopping of this hormone supplement results in hunger is unsuppressed, making excessive eating far more likely."
An Ongoing Condition?
Health authorities advise the jabs for people with weight-linked medical conditions, accompanied by prescribed diet and exercise modifications.
A number of clinicians argue that, due to the likelihood of relapse, the therapy is often ongoing.
This opinion is reinforced by drug manufacturers, who note that the results "highlight the persistent nature of excess weight," comparing it to managing conditions like high blood pressure.
User Accounts
Individuals who have come off the jabs report a intense resurgence of hunger.
"It felt as if something activating and I was suddenly starving," recalled a patient.
This challenge is compounded if users have not established sustainable dietary or behavioural modifications during therapy.
Widespread Adoption
Survey data suggest that a significant number of adults in the UK have used weight-loss jabs in the past year, with desire remaining high.
- Adoption is greater among women than males.
- The middle-aged age group shows the greatest usage rates.
- A large proportion access the drugs through private healthcare rather than the NHS.
Finally, researchers stress that while these medications are potent agents for weight loss, they are not a permanent fix and maintained weight loss likely depends on integrated lifestyle management.
