Fresh analysis reveals that patients who come off new weight-loss injections like semaglutide or tirzepatide may regain lost weight far faster than those who stop traditional lifestyle regimens.
Published data in a leading health publication shows that while obese people frequently drop about a fifth of their total mass while undergoing treatment, the mass returns at an estimated rate of nearly a kilo each month upon discontinuation.
"Users using such drugs should be informed of the danger of rapid weight regain when the treatment is stopped," warns lead investigator Dr. Susan Jebb.
That rate of regain implies a reversion to original mass in about a year and a half.
Weighing Treatments
The study, which examined dozens of trials involving over 9,000 of participants, contrasted the outcomes of these new drugs with conventional dieting.
Researchers point out that people who shed pounds through dieting typically have a more gradual creep back—around 100 grams monthly—once they finish.
Understanding the Fast Rebound
Experts propose the mode of action of the drugs is key to understanding the accelerated rebound.
These medications imitate a body's own chemical called GLP-1, which helps regulate feelings of fullness.
"Artificially providing GLP-1 concentrations far above than the body's typical production could lead to the system to produce less of its own natural hormone, and may also diminish sensitivity to its actions," said Dr. Adam Collins, a dietetics expert.
"Stopping of this GLP-1 'fix' results in hunger is uncontrolled, making overeating much more probable."
A Lifelong Issue?
Medical guidelines suggest the injections for people with weight-linked medical conditions, alongside prescribed diet and exercise modifications.
Professionals contend that, considering the likelihood of relapse, the therapy is often ongoing.
This opinion is reinforced by drug manufacturers, who say that the findings "underscore the chronic character of excess weight," akin to managing diseases like high blood pressure.
Patient Testimonies
Users who have discontinued the jabs describe a intense resurgence of appetite.
"It felt as if something flipping and I was suddenly extremely hungry," said an individual.
The struggle is exacerbated if individuals have not established sustainable lifestyle or habit changes during treatment.
Growing Adoption
Recent estimates suggest that a significant number of adults in the UK have tried these injections in the past year, with interest being substantial.
- Use is more common among females than males.
- The 40s and 50s age group shows the highest usage rates.
- A large proportion access the medications through private prescriptions rather than the NHS.
Finally, clinicians caution that while the jabs are powerful agents for weight loss, they are not a permanent fix and maintained weight loss likely depends on combined lifestyle support.
