Your basically only eating 1 chicken breast, 1 can tuna, and 8 eggs all day. Then you have a 12 hour window with no food at all. See the problem yet? Your only getting alittle over a 100 grams protein from food. You need to triple this. Cut out all that bread and eat some oats, rice, and potatoes for carbs. Maybe a little pasta here and there. Add some veggies in aswell.
