What is the fastest way to enter foods on the iPhone?
Go to a meal (e.g. breakfast), tap the “+” button in the top right corner, which will take you to the Breakfast Entry screen. There, type several words from the food name. As you type, the foods are found and displayed in the list to the right. Once you see the one you need, tap it. The food’s full name is displayed below the Food Name Search box, and you will be taken to the Amount box. Type a number (e.g. 2) and tap on a serving size in the list on the right (e.g. “oz”). You’ll see calories and weight calculated below the Amount box. Next, tap the Save button, and you’ll be taken back to the Meal screen (breakfast, in this example), where you should see the name of the food and the corresponding number of calories. If you want to enter another food, repeat the process starting from tapping the “+” button.
