ようになる・
A verb can't go straight before なる or する. With ように in between, ようになる is a change that has come about: now you can, or now you do. ようにする is making a point of doing something.

making a point of it

読めるようになる, 食べるようになる. "No longer" is usually なくなる: 食べなくなる.
ようにする
Verb (dictionary form or ない-form) + ようにする
食べるようにする, 食べないようにする. A habit you keep up is ようにしている.
ようになる: now you can
After a potential form: you couldn't before, and now you can. English says "can now" or "learned to".
