New research indicates that individuals who stop using new weight-loss injections like semaglutide or tirzepatide tend to recover reduced body mass much more quickly than those who halt traditional lifestyle plans.
Research printed in a major health publication shows that while overweight people frequently drop a large proportion of their total mass while undergoing treatment, the weight comes back at an estimated rate of 0.8 kg per month after stopping.
"Users buying these treatments need to be cognizant of the danger of fast rebound weight gain when the therapy is stopped," cautioned lead investigator Dr. Susan Jebb.
Such speed of regain implies a reversion to pre-treatment mass within about 18 months.
Analyzing Approaches
The analysis, which reviewed 37 of trials involving thousands of participants, contrasted the results of these new drugs with other pills.
The team note that people who lose weight through diet and exercise generally have a less rapid creep back—approximately 0.1 kg a month—after stopping.
Understanding the Fast Regain
Experts suggest the mode of action of the drugs accounts for the heightened regain.
The injections copy a natural hormone called GLP-1, which controls hunger.
"Long-term administration of GLP-1 levels far above than normal might result in the system to produce less of its endogenous hormone, and may also lessen responsiveness to its actions," noted Dr. Adam Collins, a dietetics researcher.
"Discontinuation of this GLP-1 'fix' results in hunger is uncontrolled, making binge eating much more probable."
An Ongoing Disease?
Health authorities advise the jabs for people with weight-linked health risks, alongside recommended lifestyle changes.
A number of clinicians argue that, considering the high risk of relapse, the treatment might need to be ongoing.
This opinion is echoed by pharmaceutical companies, who note that the findings "underscore the chronic character of obesity," akin to managing diseases like diabetes.
User Experiences
People who have come off the medication describe a powerful resurgence of cravings.
"I experienced a trigger activating and I was suddenly extremely hungry," said a patient.
This challenge is worsened if individuals have not adopted lasting lifestyle or habit modifications during treatment.
Widespread Interest
Recent estimates indicate that millions of people in the UK have tried these injections in the past year, with interest being substantial.
- Use is greater among women than males.
- The middle-aged age group shows the highest usage rates.
- Many access the drugs through private healthcare rather than public health services.
In conclusion, researchers emphasize that while the jabs are powerful tools for shedding pounds, they are not a standalone solution and long-term success relies on ongoing lifestyle changes.
