Fresh analysis indicates that individuals who come off popular weight-loss injections like semaglutide or tirzepatide can put back on lost weight at a significantly accelerated pace than those who stop traditional lifestyle programs.
Published data in a leading health publication demonstrates that while overweight individuals often shed a large proportion of their body weight while on the medication, the mass comes back at an estimated rate of 0.8 kg per month after stopping.
"Users using these treatments should be informed of the danger of fast rebound weight gain when the medication ends," cautioned lead investigator Dr. Susan Jebb.
This pace of regain suggests a reversion to pre-treatment mass within about one and a half years.
Comparing Approaches
The research, which looked at dozens of trials involving over 9,000 of patients, contrasted the outcomes of GLP-1 agonists with other pills.
The team note that people who lose weight through dieting usually see a more gradual weight regain—around 100 grams monthly—after stopping.
The Reason for the Quick Rebound
Experts suggest the way of the jabs is key to understanding the amplified rebound.
The injections mimic a natural hormone called glucagon-like peptide-1, which controls appetite.
"Long-term administration of GLP-1 concentrations several times higher than the body's typical production might result in the system to generate a reduced amount of its endogenous hormone, and could reduce sensitivity to its effects," noted Dr. Adam Collins, a nutrition specialist.
"Stopping of this medication leads to hunger is unsuppressed, making binge eating far more likely."
A Lifelong Issue?
Health authorities advise the jabs for individuals with weight-linked health risks, accompanied by recommended diet and exercise modifications.
Many experts contend that, considering the high risk of weight regain, the treatment might need to be ongoing.
This opinion is echoed by pharmaceutical companies, who state that the results "highlight the persistent character of excess weight," akin to managing diseases like hypertension.
Patient Experiences
People who have come off the medication describe a intense resurgence of cravings.
"I experienced a trigger flipping and I was suddenly extremely hungry," said an individual.
The struggle is compounded if users have not developed lasting dietary or behavioural modifications during treatment.
Significant Use
Recent estimates suggest that a significant number of people in the UK have used these injections in the past year, with interest being substantial.
- Adoption is higher among women than males.
- The middle-aged demographic shows the greatest level of interest.
- Many obtain the drugs through private prescriptions rather than public health services.
Ultimately, experts emphasize that while these medications are powerful tools for shedding pounds, they are not a permanent fix and long-term success hinges on combined lifestyle changes.
