Weight loss benefits of Tirzepatide persist after stopping treatment in Chinese adults

Obesity has become a global epidemic, contributing to a host of chronic health conditions such as type 2 diabetes, hypertension, and cardiovascular disease. In China, rising rates of overweight and obesity have become a major public health concern. While lifestyle interventions such as diet and exercise remain first-line treatments, long-term success is often limited due to frequent weight regain once interventions stop.
Tirzepatide is a dual GIP/GLP-1 receptor agonist that has shown remarkable weight loss efficacy in global clinical trials. In China, the SURMOUNT-CN trial marked the first phase 3 study evaluating tirzepatide in overweight and obese adults. While the trial previously reported up to 20% average weight loss after 52 weeks of treatment, the long-term durability of these effects after stopping medication was unknown.
In a recent study published in Life Metabolism, researchers at Fudan University report that even after stopping the anti-obesity drug tirzepatide, Chinese obese individuals can maintain significant weight loss. Briefly, 152 Chinese adults who completed the full 52-week tirzepatide regimen (10 mg or 15 mg doses) were followed for an additional 26 weeks without any anti-obesity drugs or bariatric surgery. The results showed that obese individuals maintained an average weight loss of 8.7% to 10.6% compared to baseline, significantly higher than the placebo group’s 2.5%. Waist circumference remained substantially reduced (by over 10 cm in both tirzepatide groups). Cardiometabolic markers, including HbA1c, total cholesterol, and LDL cholesterol, also continued to show improvement trends. These findings support the idea that tirzepatide has lasting benefits even after discontinuation. This is the first real-world evidence of post-treatment weight loss durability with tirzepatide in a Chinese population. It provides valuable guidance for future obesity treatment strategies and highlights the need for long-term management plans that extend beyond active therapy.

Curtin University researchers have undertaken the world’s biggest survey of low frequency satellite radio emissions, finding Starlink satellites are significantly interfering with radio astronomy observations, potentially impacting discovery and research.
Unintended signals from satellites - leaked from onboard electronics - can drown out the faint radio waves astronomers use to study the universe.
Researchers from the Curtin University node of the International Centre for Radio Astronomy Research (ICRAR), hosted at the Curtin Institute of Radio Astronomy (CIRA), focused on the Starlink mega-constellation as it has the most satellites in orbit, at ...

When women political candidates deviate from expectations or the views of their party, they are judged far more harshly than men by voters, a new study in Politics & Gender, published on behalf of the American Political Science Association by Cambridge University Press, reveals.
The research also found that voters begin campaigns with greater uncertainty about women candidates than about men, leading them to scrutinise women candidates to a greater extent when forming opinions of them.

A team led by the Trottier Institute for Research on Exoplanets (IREx) has achieved the most precise study to date of the L 98-59 planetary system, and confirmed the existence of a fifth planet in the star’s habitable zone, where conditions could allow liquid water to exist.
Volcanic planets, a sub-Earth, and a water world
L 98-59, a small red dwarf located just 35 light-years from Earth, hosts three small transiting exoplanets discovered in 2019, thanks to NASA's TESS space telescope, and a fourth planet revealed through radial velocity measurements with the European Southern Observatory's ESPRESSO spectrograph. All four planets orbit their parent star in ...

(SACRAMENTO, Calif.) — The UC Davis Department of Ophthalmology has received a five-year, $3.6 million grant from the National Eye Institute to explore a new way to treat vision loss using gene therapy.
The research could lead to safer and more effective treatments for people with serious eye diseases like macular degeneration and inherited blindness. It could also lead to treatments that don’t require surgery and can be done more widely in clinics.
“We’re excited ...

As the climate becomes warmer on average, it makes intuitive sense that we will see more hot days and we've had predictions of this for some time. However, the duration of heatwaves — how many days in a row exceed a temperature that is unusually hot for a given region — can be very important for impacts on humans, livestock and ecosystems. Predicting how these durations will change under a long-term warming trend is more challenging because day-to-day temperatures are correlated — tomorrow's temperatures have a dependence on today's temperature. This study takes ...

GLP-1 receptor agonists, a class of drug used to treat type 2 diabetes, likely trump the widely prescribed metformin for curbing dementia risk in people with the condition, finds the largest study of its kind, published in the open access journal BMJ Open Diabetes Research & Care.
The findings suggest that future clinical guidelines for the treatment of type 2 diabetes would do well to consider prioritising drugs with both blood glucose and neuroprotective effects, say the researchers.
Published research suggests that both GLP-1 receptor agonists and metformin, which are widely used to treat type 2 diabetes, protect the brains of people with the disease. But as ...

The annual UK cost of the mental health disorder PTSD is likely to top £40 billion, but the figures are based on 2020-1 prevalence rates—the most recently available—and don’t include many indirect costs, such as family support services, finds a cost analysis published in the open access journal BMJ Open.
The societal and financial impacts of this increasingly common condition have been “gravely” undervalued, conclude the researchers.

MIAMI, FLORIDA (July 22, 2025) – LaShae Rolle, 27, is a competitive powerlifer who could squat 441 pounds, bench 292 pounds and deadlift 497 pounds. She is also a breast cancer survivor and researcher and the lead author on a first-of-its kind study documenting elite-level strength training during active breast cancer treatment.
The study challenges the long-held belief that cancer patients should stick to low- or moderate-intensity exercise and suggests that with individualized and symptom-informed exercise planning, even ...

Most parents can think back to the first ultrasound image they saw of their unborn child, and may even be able to remember what impression that image had on them. Would their child be an active toddler, a tad bit ornery or stubborn, sweet and cuddly, fiercely independent, or shy and cooperative? New research suggests these initial perceptions may have been formed, at least in part, in response to how the health care provider described the baby during the exam.
These prenatal care experiences play a large role in shaping how parents ...
