Can lean beef really be considered lean?

Hi, there. I am just now learning how to cook healthy meals. I made some 90% lean beef chilli this weekend and I still have tons left over. I was going to take some for work today, but then, I'm not sure if I should. If I'm trying to limit my diet to mostly lean meat with occasional red meat and cheats here and there (like lean meat all week, red meat once on the weekend), is this a good idea? Thank you.
