Food logging
Food logging is writing down what was eaten, with quantities, so that a day's calories and macros can be known rather than guessed. IZeat is food logging with no data entry screen: the customer says the meal to ChatGPT or Claude, the assistant writes it to IZeat, and the reply is the receipt of what was recorded.
Dietary self-monitoring took 23.2 minutes a day in the first month of a 2019 trial, and fewer than half of participants were still logging after week ten (content/sources.md, S5). What people describe as unbearable is not the counting but the input: search, pick among ten entries, fix the portion, repeat. IZeat removes the screen. One meal is one sentence, the assistant converts cups and ounces to grams, and every item keeps the source of its figures.
Logging fails at the keyboard, not in the kitchen. The people who stop are not the ones who lack numbers; they are the ones for whom six items, four times a day, for ninety days became unbearable to type. IZeat's whole bet is that the same record, said to an assistant that already knows how to talk, costs little enough to keep, and that keeping it is where the results come from.
Put it into practice: Logging a meal.
