New research reveals that people who stop using popular weight-loss injections like semaglutide or tirzepatide can put back on lost weight at a significantly accelerated pace than those who halt traditional lifestyle regimens.
Published data in a leading medical journal shows that while overweight individuals often shed about a fifth of their body weight while undergoing treatment, the mass returns at an estimated rate of 0.8 kg per month after stopping.
"Individuals buying these treatments must be cognizant of the danger of fast weight regain when the treatment is stopped," warns lead investigator Dr. Susan Jebb.
That rate of regain implies a return to pre-treatment weight in about 18 months.
Comparing Approaches
The analysis, which examined 37 of studies involving over 9,000 of patients, compared the results of these new drugs with conventional dieting.
Researchers emphasize that individuals who lose weight through lifestyle changes alone usually see a slower weight regain—around 0.1 kg a month—once they finish.
Explaining the Quick Rebound
Experts propose the way of the drugs is key to understanding the accelerated regain.
These medications mimic a body's own chemical called glucagon-like peptide-1, which controls appetite.
"Long-term administration of GLP-1 concentrations several times higher than normal might result in the body to produce less of its own natural GLP-1, and could diminish responsiveness to its effects," said Dr. Adam Collins, a nutrition researcher.
"Discontinuation of this medication leads to appetite is unsuppressed, making excessive eating much more probable."
A Lifelong Issue?
Medical guidelines recommend the injections for people with weight-linked health risks, accompanied by prescribed diet and exercise modifications.
Many experts say that, due to the significant potential of relapse, the therapy should be considered life-long.
This view is supported by pharmaceutical companies, who note that the results "emphasize the long-term nature of obesity," comparing it to managing diseases like high blood pressure.
User Experiences
People who have come off the medication report a intense return of cravings.
"It was like a switch flipping and you become ravenous," said an individual.
The struggle is exacerbated if users have not developed permanent lifestyle or habit modifications during treatment.
Widespread Adoption
Recent estimates suggest that a significant number of adults in the UK have used these injections in the past year, with demand being substantial.
- Adoption is greater among females compared to males.
- The 40s and 50s age group shows the highest level of interest.
- Many obtain the drugs through private healthcare rather than the NHS.
In conclusion, clinicians emphasize that while the jabs are potent tools for shedding pounds, they are not a standalone solution and maintained weight loss hinges on integrated lifestyle management.
