Be proud you ate fruit. It sounds like about 300 calories, maybe 400. Stick to your plan now. Why don't you eat normally? (Fruits, veggies, protein and some fiber whole wheat carbs.) Sounds like your body is craving fruits and vegetables. Besides, there is a study from The American Psychological Association that states there is lower depression among people who eat like I said above. Good luck to you! You can do this! It's all up to you!
By the way, I tried every diet there is, and I find fibrous carbs, proteins, veggies and fruit are the best for me, too! Count cals to get started. I believe in you!
