I'm working on something just for this, no A.I required. Most of the problems with eating healthy in my opinion is just being prepared with the stuff to make and deciding what to make in advance. Most of the problems I've found with existing "food/recipe sites" is they quickly devolve into "branded advertising", "data collection", and/or "choice overload." Does any site really need over 10,000 choices of "chicken soup" recipes? The other problem with the Internet (there are always more problems with the Internet) is when you search for recipes in the uncurated web, every recipe is prefixed by an intensely personal story about the family you don't even know. Once you find that recipe, it's in a tiny hard to read box (I don't know who made this template) that naturally has been made very hard to copy and paste elsewhere.
Its a terrible user experience.
My idea isn't ready yet, but I'm furiously working on the MVP.
