Fresh analysis suggests that people who discontinue popular GLP-1 drugs like semaglutide or tirzepatide may regain lost weight much more quickly than those who end conventional lifestyle regimens.
Published data in a leading medical journal points out that while obese individuals often shed a large proportion of their body weight while undergoing treatment, the mass is regained at an average rate of nearly a kilo each month upon discontinuation.
"Users purchasing such drugs need to be cognizant of the danger of fast weight regain when the medication ends," cautioned researcher Dr. Susan Jebb.
Such speed of recovery implies a reversion to starting weight in about one and a half years.
Analyzing Approaches
The study, which looked at dozens of studies involving over 9,000 of patients, contrasted the effects of these new drugs with older methods.
Scientists emphasize that individuals who shed pounds through diet and exercise typically have a less rapid creep back—approximately 100 grams monthly—once they finish.
Understanding the Fast Rebound
Experts believe the way of the jabs accounts for the amplified regain.
GLP-1 drugs imitate a natural hormone called GLP-1, which helps regulate feelings of fullness.
"Sustained high doses of GLP-1 concentrations far above than the body's typical production might result in the body to generate a reduced amount of its endogenous GLP-1, and may also lessen responsiveness to its effects," said Dr. Adam Collins, a nutrition expert.
"Stopping of this GLP-1 'fix' means appetite is no longer kept in check, making binge eating a significant risk."
A Lifelong Issue?
The NHS recommend the jabs for individuals with obesity-related health risks, accompanied by recommended diet and exercise modifications.
Professionals argue that, due to the significant potential of relapse, the therapy should be considered ongoing.
This opinion is reinforced by drug manufacturers, who state that the results "underscore the long-term nature of excess weight," similar to managing diseases like hypertension.
Patient Testimonies
People who have come off the jabs explain a intense return of hunger.
"It felt as if a switch activating and I was suddenly ravenous," described an individual.
This challenge is exacerbated if patients have not developed lasting dietary or behavioural changes during treatment.
Growing Interest
Figures show that millions of people in the UK have used these injections in the past year, with desire remaining high.
- Adoption is higher among females than men.
- The 40s and 50s demographic shows the highest level of interest.
- Many access the drugs through private prescriptions rather than the NHS.
Finally, experts caution that while these medications are effective agents for weight loss, they are not a permanent solution and maintained weight loss hinges on combined behavioural changes.
