What the research found
ScienceDaily reported on 27 October 2026 an Osaka Metropolitan University study in American Journal of Physiology-Endocrinology and Metabolism. Eight-week-old male mice were split into six groups: sham surgery or castration, with a control feed, a fructose feed, or fructose plus antibiotics. Low testosterone and fructose together increased liver triglycerides more than either factor alone, and antibiotics blunted the rise in liver weight. The group links the extra fat to gut-bacteria changes and higher pyruvate in the cecum; mouse liver cells in a dish stored more neutral lipid when pyruvate and fructose were combined. This is an animal and cell study, not a human diet trial and not a treatment for fatty liver. Not medical advice.
Evidence level: Animal study. Results in animals or cells often don't carry over to people.
