I'm a paleo eater so cook from scratch. All the actual food is listed as, say, C-green beans or P-pork chop etc, where C is crb, P is protein and F is fat. I also do an S for salada. Fitday will store foods alphaetically, bunching all the carbs together, under C then in alpha order within C.
I also am starting to save my main meals, one serving, for each day, by weeks, For example todays dinner will be curried salmon, so its listed as 4804-curried salmon, which means week 48, day 04. I add any side or salads plus breakfast foods come from the Cs and Ps which are already listed.
I only use fitday to get an accurate idea of nutritional input. I want around 75% of my calories from fat, about 20% as protein and 5% as carbs. But moderate protein (around 60-70 grams per day) and calories at 1800 a day or a bit less. Imagine doing this without fitday!
Once you set up your custom foods, its very fast to enter things. And you just enter as you go along, its always a work in progress.
