According to one embodiment, an electronic device includes a biological information acquisition processor, a body condition estimation processor, and a motion change detector. The biological information acquisition processor acquires biological information of a living body including information about the living body. The body condition estimation processor estimates a body condition of the living body based on the biological information. The motion change detector detects a motion change of the living body based on the biological information. The body condition estimation processor corrects a reference value used during body condition estimation or changes a body condition estimation method based on the motion change of the living body.
