There is no accurate way to answer this questions being as everyones metabolism is different. I do have a few questions:
1) Why only fruits for breakfast? You need protein. Your muscles are staving in the mornings. Remember, the word breakfast means to break the fast.
2) Are you only eating 3 x's per day? That will slow your metabolism. You need 4-6 meals per day. Invest in a high quality protein shake if whole food is not always an option.
