Glucose metabolism and energy expenditure.

<p><b>A</b>. Plasma glucose concentrations in <i>ad libitum</i> fed wild-type and ob-norm mice that were maintained on a high-fat diet (open bars) or low-fat diet (filled bars). <b>B</b>. Plasma insulin concentrations of wild-type and ob-norm mice at 18 and 26 weeks of age that were maintained on a high-fat diet (open bars) or low-fat diet (filled bars). <b>C</b>. Plasma glucose concentrations in response to a glucose injection in wild-type (black) and ob-norm (red) mice. Triangles represent mice on a low-fat diet and squares represent mice on a high-fat diet. * indicates p<0.05. <b>D</b>. Average beam breaks per minute for wild-type and ob-norm mice maintained on a low-fat (filled bar) or high-fat (open bar) diet. <b>E</b>. Average oxygen consumption for wild-type and ob-norm mice in the light phase (open bars) and dark phase (closed bars).
