Fig. 2.

Biometrics and serum parameters in obesity-prone mice fed during 21 days a semi-synthetic low-fat diet (LF group), a high-fat diet (HF group) or a high-fat diet with simultaneous oral daily treatment with resveratrol (30 mg/kg bw/day, HF + RSV group) or hydroxytyrosol (20 mg/kg bw/day, HF + HT group). The panels show development of body weight gain (a), fat body content at day 4 (b) and 20 (c) and the following parameters measured at the final end point of the experiment (day 21): inguinal (d), epididymal (e) and retroperitoneal (f) white adipose tissue depot weights, subcutaneous/visceral fat ratio (g) and serum glucose (h), insulin (i) and non-esterified fatty acids (NEFA, j) levels. Data are means + SEM (n = 7–10). Significant differences between groups were tested by one-way ANOVA and least-significant difference (LSD) post hoc comparisons (P < 0.05). Values not sharing a common letter are statistically different
