How do I log food?

Just text what you ate, like "grilled chicken salad for lunch", or start with "log:" to make sure it is saved. You can also send a photo of your meal or of a barcode on packaged food; I estimate the nutrition, then you tap "Breakfast", "Lunch", "Dinner" or "Snack" to save it (on plain SMS, reply with the number). Logging is free and does not use up your questions.
