High-fat feeding-induced obesity with hepatic steatosis. (a) Typical images of NF and HF zebrafish. (b – d) Body weight (b), body length (c) and BMI (d) were increased by HF. n = 10, *P < 0.05, **P < 0.01. (e – f) HF increased plasma TG (e) on day 21, however it did not alter the level of fasting blood glucose (f). n = 10, *P < 0.05. ns means no significant difference. (g) Oil Red O staining of liver. Red colour indicates lipid droplets in the liver. (h) Quantification of the red area in (g). n = 10, **P < 0.01. (i) HF increased the level of hepatic lipids more than NF. n = 4, *P < 0.05
