A recent study indicates that individuals who discontinue popular GLP-1 drugs like semaglutide or tirzepatide tend to recover reduced body mass much more quickly than those who stop traditional diet and exercise programs.
Research printed in a major health publication demonstrates that while overweight individuals frequently drop about a fifth of their body weight while undergoing treatment, the weight is regained at an estimated rate of 0.8 kg per month upon discontinuation.
"Users purchasing these drugs should be informed of the potential of fast rebound weight gain when the medication ends," cautioned expert Dr. Susan Jebb.
Such speed of recovery suggests a reversion to original weight within about one and a half years.
Comparing Therapies
The research, which reviewed dozens of studies involving over 9,000 of patients, compared the results of these new drugs with older methods.
Scientists note that people who lose weight through diet and exercise generally have a more gradual weight regain—around 100 grams monthly—after stopping.
Explaining the Fast Regain
Doctors believe the mode of action of the jabs accounts for the accelerated rebound.
GLP-1 drugs imitate a body's own chemical called glucagon-like peptide-1, which controls feelings of fullness.
"Artificially providing the hormone concentrations far above than normal could lead to the body to produce less of its own natural hormone, and may also lessen sensitivity to its effects," said Dr. Adam Collins, a nutrition specialist.
"Withdrawal of this GLP-1 'fix' means appetite is no longer kept in check, making binge eating far more likely."
An Ongoing Disease?
Medical guidelines recommend the injections for people with weight-linked health risks, alongside recommended diet and exercise modifications.
A number of clinicians contend that, due to the likelihood of weight regain, the therapy should be considered ongoing.
This view is supported by pharmaceutical companies, who state that the findings "emphasize the long-term character of excess weight," comparing it to managing conditions like high blood pressure.
Patient Experiences
Individuals who have stopped the jabs explain a sudden resurgence of cravings.
"I experienced a trigger that goes on and I was suddenly ravenous," said one woman.
This difficulty is exacerbated if patients have not established lasting lifestyle or habit modifications during treatment.
Significant Use
Recent estimates indicate that a significant number of adults in the UK have used these injections in the past year, with desire being substantial.
- Adoption is greater among females than males.
- The middle-aged age group shows the greatest usage rates.
- Many obtain the medications through private healthcare rather than public health services.
In conclusion, clinicians caution that while GLP-1 drugs are powerful agents for weight loss, they are not a standalone cure and maintained weight loss hinges on integrated lifestyle management.
