I-(topic marker)-ate-only-therefore-stomach-(subject marker)-full-is
I just ate so I'm full.
Notes: Here we have the past tense 食べた therefore ばかり means the event just happened.
Basically ばかり means there is nothing but what is stated. When the verb is in the past tense it takes the meaning of "just happened" which really means "since that time nothing else has happened."
