New research suggests that people who come off blockbuster weight-loss injections like semaglutide or tirzepatide can put back on reduced body mass much more quickly than those who halt traditional lifestyle programs.
Research printed in a leading health publication points out that while overweight individuals frequently drop substantial amounts of their body weight while undergoing treatment, the weight comes back at an average rate of 0.8 kg per month upon discontinuation.
"Individuals buying these medications should be cognizant of the risk of rapid rebound weight gain when the therapy is stopped," warns researcher Dr. Susan Jebb.
Such speed of recovery implies a return to starting mass in about a year and a half.
Analyzing Therapies
The analysis, which examined 37 of trials involving thousands of participants, contrasted the outcomes of GLP-1 agonists with conventional dieting.
Researchers point out that individuals who shed pounds through diet and exercise generally have a slower creep back—around 0.1 kg a month—once they finish.
Understanding the Fast Rebound
Nutrition scientists suggest the mechanism of the jabs is key to understanding the heightened regain.
These medications copy a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Sustained high doses of the hormone levels far above than the body's typical production might result in the body to generate a reduced amount of its own natural hormone, and may also reduce sensitivity to its effects," said Dr. Adam Collins, a dietetics researcher.
"Withdrawal of this GLP-1 'fix' results in appetite is unsuppressed, making excessive eating far more likely."
A Chronic Disease?
Health authorities recommend the injections for individuals with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Many experts contend that, considering the high risk of relapse, the treatment might need to be life-long.
This view is echoed by pharmaceutical companies, who say that the results "underscore the persistent character of excess weight," similar to managing diseases like high blood pressure.
User Experiences
Individuals who have stopped the medication report a intense return of appetite.
"It was like a switch activating and you become extremely hungry," recalled an individual.
This challenge is exacerbated if users have not adopted lasting lifestyle or habit modifications during treatment.
Widespread Adoption
Survey data indicate that a significant number of people in the UK have tried these injections in the past year, with demand remaining high.
- Use is greater among women compared to men.
- The 40s and 50s demographic shows the highest level of interest.
- A large proportion obtain the medications through private healthcare rather than the NHS.
In conclusion, researchers stress that while the jabs are potent agents for shedding pounds, they are not a magic fix and long-term success relies on integrated behavioural support.
