Fresh analysis suggests that people 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 diet and exercise regimens.
Published data in a prominent health publication points out that while overweight people often shed substantial amounts of their total mass while using the jabs, the weight comes back at an average rate of 0.8 kg per month upon discontinuation.
"Users buying these drugs must be aware of the danger of fast rebound weight gain when the therapy ends," cautioned lead investigator Dr. Susan Jebb.
This pace of recovery means a reversion to original weight within about 18 months.
Weighing Approaches
The study, which looked at 37 of studies involving over 9,000 of patients, compared the effects of these new drugs with other pills.
The team point out that individuals who lose weight through diet and exercise usually experience a slower creep back—approximately 0.1 kg a month—once they finish.
Explaining the Rapid Regain
Experts believe the mechanism of the drugs is key to understanding the amplified rebound.
These medications copy a natural hormone called glucagon-like peptide-1, which moderates appetite.
"Sustained high doses of GLP-1 concentrations several times higher than normal might result in the body to produce less of its endogenous GLP-1, and may also diminish sensitivity to its actions," noted Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this medication leads to hunger is no longer kept in check, making overeating a significant risk."
An Ongoing Condition?
Health authorities recommend the injections for individuals with obesity-related health risks, alongside recommended lifestyle changes.
Professionals say that, considering the significant potential of relapse, the treatment might need to be long-term.
This perspective is supported by pharmaceutical companies, who state that the findings "emphasize the persistent character of excess weight," comparing it to managing diseases like hypertension.
User Testimonies
Users who have come off the medication explain a intense resurgence of hunger.
"It felt as if something that goes on and you're instantly extremely hungry," said one woman.
The struggle is compounded if patients have not established permanent dietary or behavioural changes during therapy.
Widespread Adoption
Recent estimates suggest that millions of people in the UK have used these injections in the last 12 months, with desire being substantial.
- Adoption is greater among females compared to men.
- The middle-aged age group shows the highest level of interest.
- Many access the medications through private prescriptions rather than public health services.
Ultimately, researchers caution that while the jabs are potent tools for shedding pounds, they are not a permanent cure and lasting health benefits likely depends on ongoing lifestyle support.
