Fresh analysis indicates that individuals who stop using popular weight-loss injections like semaglutide or tirzepatide may regain reduced body mass far faster than those who stop traditional diet and exercise programs.
Published data in a leading medical journal shows that while overweight people can lose substantial amounts of their body weight while undergoing treatment, the weight returns at an average rate of nearly a kilo each month upon discontinuation.
"Users using such drugs must be informed of the potential of rapid rebound weight gain when the therapy ends," cautioned lead investigator Dr. Susan Jebb.
That rate of recovery means a reversion to pre-treatment mass within about a year and a half.
Comparing Therapies
The study, which reviewed dozens of trials involving over 9,000 of participants, compared the effects of these new drugs with older methods.
Researchers emphasize that people who shed pounds through dieting usually see a slower creep back—around 0.1 kg a month—once they finish.
The Reason for the Fast Regain
Nutrition scientists suggest the way of the jabs is key to understanding the amplified weight return.
The injections copy a natural hormone called glucagon-like peptide-1, which helps regulate feelings of fullness.
"Sustained high doses of the hormone concentrations several times higher than normal may cause the body to produce less of its endogenous GLP-1, and may also lessen sensitivity to its actions," said Dr. Adam Collins, a dietetics expert.
"Stopping of this GLP-1 'fix' means appetite is no longer kept in check, making excessive eating a significant risk."
A Lifelong Disease?
Medical guidelines suggest the injections for people with obesity-related health risks, accompanied by recommended diet and exercise modifications.
A number of clinicians contend that, given the likelihood of relapse, the therapy is often long-term.
This opinion is supported by pharmaceutical companies, who state that the results "emphasize the persistent character of excess weight," comparing it to managing diseases like high blood pressure.
User Accounts
People who have come off the medication explain a powerful return of hunger.
"I experienced a switch activating and I was suddenly ravenous," recalled one woman.
This difficulty is worsened if users have not developed sustainable dietary or behavioural changes during treatment.
Widespread Interest
Figures show that millions of people in the UK have used these injections in the last 12 months, with desire remaining high.
- Adoption is more common among women than males.
- The 40s and 50s age group shows the greatest level of interest.
- Many obtain the drugs through private prescriptions rather than public health services.
In conclusion, researchers caution that while the jabs are potent agents for weight loss, they are not a standalone fix and lasting health benefits hinges on integrated behavioural changes.
