Add fruit to your oatmeal for flavor. Whatever fruit you like. Or cinnamon. Or both.
This diet is not good. You're eating very little food, and it's still mostly carbs and simple sugars. Is there any way you can eat protein more than once per day? This is going to be very difficult if you cannot. I would also only eat the fruit salad once per day. Fruit is not good for your goals, especially if you're eating it multiple times per day.
Here's what a typical day looks like for me:
8am: oatmeal or cereal, and 3 glasses of whole milk
10am: mix a protein shake (100g protein) and sip this for the next 5 hours
1pm: lunch, usually either chicken or beef with vegetables, rice, or potato
5pm: 3 glasses of whole milk
6pm: dinner, similar to lunch, but a larger portion
8pm: workout, with Plazma (Biotest product found on this site)
9pm: 3 glasses of whole milk
Do you see the difference? The difference between this and what you should be doing is the amount of milk. If I were you I would cut the milk to about 1/3 of what I drink, because I'm much bigger than you, and I'm already lean. Other than that, this approach to diet works well for most people.
