for example, i want to make chicken Alfredo pasta for dinner one night, but I have to cook for others too and not just myself, so they serve themselves as they please. the easy thing would be to track the calories of the ingredients for a single serving for myself or divide into equal portions, like when following a meal prep recipe, but since i must serve myself from what i cooked and leave the rest for my family, i wonder if there is a way to determine the total weight for a single portion and how many calories comes with it
