Density

Usually there is a clear relationship between density and moisture content. Thus bread, which has a low moisture content (about 35%) is not as dense as beef (65%); for example, 1 lb of bread requires about two-thirds as much energy as 1 lb of beef to heat to the same temperature. Thermal conductivity also comes into play in that the dimensions involved could mean substantial overheating of the surface of beef because of its density, while the more open structure of bread would not rely on thermal conductivity to the same extent.
