Intraperitoneal injections of mice with Form (20 µg/g) or saline vehicle over 24 h, measurement of food consumption, and assessments of body fat and lean mass (%) by quantitative magnetic resonance imaging were carried out as described in materials and methods. Data are presented as means ± SE; n = 7–8 mice/group; *P < 0.05 vs. Pretreatment; **P < 0.01; ***P < 0.001.
