I'd say you have to find some foods that work for you, and as you are learning, probably track your macros to ensure you aren't dipping too low in any one category. To make it "better" would really just entail making it work for you and work efficiently and with ease. This could mean doing some meal prep and getting a lot of food made in one day so when you are feeling lazy you've got something already made. It definitely means eating enough.
