Is it possible to live off only vegetables, fruits, nuts, vitamins, and protein shakes? Does anyone else have this diet?

I'll be living on my own soon and I'll only have a budget of 19 bucks per day. I think switching to only veggies and fruit will save me money. I also need to change my diet because I have arthritis and was told a gluten free diet really helps ease pain. I just want to know if anyone else has this diet? What are some tips?
