Abstract: A body composition analyzer using a bioelectric-impedance method includes a display unit for displaying measurement results including a weight and a body fat ratio, and a processor responsive to a user's input for causing the display means to display a part of the measurement results. In one embodiment, the display unit displays at least the body fat ratio, and the measurement result caused to be displayed by the processor is one of basal metabolism data, visceral fat data, muscle mass data, and bone mass data. The display unit displays an item selected from among the basal metabolism data, the visceral fat data, the muscle mass data, and the bone mass data if the item is designated by the user while the body fat ratio is being displayed, and then displays another item if that item is subsequently designated by the user. Thus, a main measurement result and a desired secondary measurement result can be viewed without waiting, and two or more desired secondary measurement results can be selected and viewed.
