Fat distribution, especially increased visceral fat, may be as important as overall obesity in increasing risk of heart disease, type 2 diabetes and certain cancers. Risk of disease, as well as visceral fat, increases dramatically with age. Cross-sectional data suggests that increased risk of disease may be largely prevented if the age related increase in visceral fat does not occur. The objective of this short review is to present data that shows visceral fat increasing over 200% in men and 400% in women between the 3 and 7 decades, show that a combination of weight gain, loss of muscle, and a shift from peripheral to central fat patterning contributes to this increase, and identify hormones that may be responsible for the shift. Finally, the review will show how participation in exercise can slow the age related shift in visceral fat.

Department of Gastrointestinal Surgery, Tongji Hospital, Tongji Medical College, Huazhong University of Science and Technology, 1095 Jiefang Av, Wuhan 4300030, PR China.
Purpose: This study aimed to investigate the relationship between visceral obesity and various disease traits, as well as to identify potential safe targets for the prevention and treatment of visceral obesity.
Study Design: Univariable and multivariable Mendelian randomization (MR) analyses were performed to examine the associations between visceral obesity and 1883 disease traits. Furthermore, we assessed the potential effect of 1684 protein expressions on visceral obesity using the available quantitative trait locus data for plasma proteins.
Effect of a Ketogenic Diet on Metabolic Dysfunction-Associated Steatotic Liver Disease (MASLD) Progression: A Randomized Controlled Trial.
JGH Open
January 2025
Division of Gastroenterology, Department of Medicine Chulalongkorn University Bangkok Thailand.
Background: Despite the popularity of a ketogenic diet, no randomized, controlled trials have evaluated its efficacy on metabolic dysfunction-associated steatotic liver disease (MASLD) progression.
Methods: We conducted an 8-week, open-label, randomized controlled trial involving 24 patients with MASLD who were randomly assigned to either the home delivery ketogenic diet or a nutrition education program on adherence to the DASH diet. The primary outcome was a reduction in hepatic steatosis as measured by transient elastography.
Prevalence of overweight and obesity in 6-15-year-old boys and girls before the COVID-19 pandemic: results from anthropological research 2001-2019 in the Czech Republic.
Cent Eur J Public Health

Department of Public Health and Hygiene, Faculty of Medicine, Pavol Jozef Safarik University in Kosice, Kosice, Slovak Republic.
Objective: Childhood overweight and obesity has been a major global problem for a long time, with a steadily increasing prevalence of obesity and a growing number of cases of serious health complications associated with childhood obesity. The main objective of the study is to assess the prevalence of overweight and obesity in boys and girls before the COVID-19 pandemic in the Czech Republic.
Methods: Body height, weight, BMI, and body composition (fat free mass, skeletal muscle mass, body fat, visceral fat area) were assessed in a cohort of 4,475 subjects (2,180 boys and 2,295 girls) aged 6-15 years.
Dapagliflozin modulates hepatic lipid metabolism through the proprotein convertase subtilisin/kexin type 9/low density lipoprotein receptor pathway.

The Second Affiliated Hospital, Zhengzhou University, Zhengzhou, China.
Background: Proprotein convertase subtilisin/kexin type 9 (PCSK9) is mainly secreted by the liver, and plays a crucial role in lipid metabolism disorder. Sodium-glucose cotransporter 2 inhibitors (SGLT2i) can regulate lipid metabolism through various pathways, including reducing visceral fat accumulation, modulating serum lipoprotein levels and alleviating hepatic steatosis. However, the specific regulatory mechanisms remain unclear.

Background: Immunotherapy and radiotherapy play crucial roles in the transformation therapy of locally advanced pancreatic cancer; however, the exploration of effective predictive biomarkers has been unsatisfactory. With the rapid development of radiomics, next-generation sequencing, and machine learning, there is hope to identify biomarkers that can predict the efficacy of transformative treatment for locally advanced pancreatic cancer through simple and non-invasive clinical methods. Our study focuses on using computed tomography (CT), positron emission tomography/computed tomography (PET/CT), gene mutations, and baseline carbohydrate antigen 199 (CA199) to identify biomarkers for predicting the efficacy of transformative treatment.
