Log food
Add a product or meal from the database to a meal on a day.
MCP tool fitatu_write → log_food
write
Adds one product or meal from search_food to the chosen meal and day, in grams, milliliters or a handy measure the product offers, such as a slice or a package. It reaches no one and is undone with one call, delete_diary_item, so it runs without asking first.
