Antibiotic treatment prevented high-fat diet–induced adipocyte hypertrophy. A: Adipocyte size distribution (%). B: Adipocyte mean area (μm2). C: Cell density (arbitrary unit). D: Representative adipose tissue staining in mice fed normal diet (CT), normal diet and antibiotics (CT-Ab), high-fat diet
(HF), or high-fat diet and antibiotics (HF-Ab) for 4 weeks. Data are means ± SE. Data with different superscript letters are
significantly different (P < 0.05) according to the post hoc ANOVA statistical analysis.
