The electronic food diary that we have developed includes a photo menu of food items in order to let users determine the potion size of each food item easily. First, users choose a food or drink item from the menu list. Then, they choose the portion size from the list “0.25, 0.5, 0.75, 1, 1.25, 1.5, 2, 2.5, 3, 3.5, 4, 5” judging from the picture shown on the screen.
