I'm a bit confused. I read it differently than y'all.   Ihaven't eaten in two weeks because i dont want to eat junk food and gained weight because of that.  I read this as she hadn't eaten in two weeks because she doesn't want to eat junk food because that's what made her gain weight initially. Are we certain that's not how she meant to say it? She doesn't exactly seem like the most literate person in the world.
