Fresh analysis indicates that individuals who stop using blockbuster GLP-1 drugs like semaglutide or tirzepatide tend to recover reduced body mass at a significantly accelerated pace than those who end traditional lifestyle regimens.
Published data in a prominent health publication points out that while obese individuals can lose about a fifth of their body weight while using the jabs, the weight returns at an average rate of 0.8 kg per month once they quit.
"Users purchasing these medications must be informed of the potential of fast weight regain when the medication concludes," warns lead investigator Dr. Susan Jebb.
This pace of regain implies a reversion to original weight in about 18 months.
Comparing Treatments
The research, which examined 37 of trials involving thousands of patients, contrasted the outcomes of these new drugs with other pills.
Researchers emphasize that individuals who shed pounds through diet and exercise typically have a slower creep back—approximately 0.1 kg a month—post-intervention.
The Reason for the Fast Rebound
Experts propose the way of the jabs explains the heightened weight return.
These medications imitate a body's own chemical called GLP-1, which controls hunger.
"Artificially providing GLP-1 concentrations far above than the body's typical production might result in the system to produce less of its own natural hormone, and may also reduce sensitivity to its actions," said Dr. Adam Collins, a dietetics expert.
"Stopping of this hormone supplement leads to appetite is unsuppressed, making binge eating far more likely."
A Chronic Disease?
The NHS advise the injections for people with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
Professionals contend that, considering the significant potential of relapse, the therapy should be considered life-long.
This opinion is echoed by drug manufacturers, who state that the results "highlight the long-term nature of excess weight," comparing it to managing conditions like high blood pressure.
Patient Experiences
Individuals who have come off the jabs describe a intense return of hunger.
"It felt as if something activating and you're instantly ravenous," described a patient.
This difficulty is compounded if users have not developed sustainable dietary or behavioural changes during treatment.
Widespread Adoption
Survey data show that a significant number of people in the UK have tried weight-loss jabs in the last 12 months, with interest being substantial.
- Adoption is more common among females compared to men.
- The 40s and 50s demographic shows the highest usage rates.
- A large proportion obtain the medications through private healthcare rather than the NHS.
Ultimately, experts caution that while the jabs are potent agents for shedding pounds, they are not a permanent cure and maintained weight loss likely depends on ongoing behavioural management.
