Trehalose treatment tended to increase body and fat mass in Wistar rats. A–F: body mass (A), the change (∆) in body mass (B), epididymal fat mass normalized to tibia length (C), total heart (D), left ventricle (LV; E), and right ventricle (RV; F) masses normalized to tibia length, and treatment consumption volume (in ml; G) per 24 h; n = 7–8 rats.
