Workout 5 days per week and cardio for 30 mins every day (do my cardio after workout in workout day). Current target is to cut body fat ( especally belly) without losing muscle. Can you guys advice on my diet plan?

Breakfast
5 tbs oats with milk

Lunch
rice-chicken breast and vege

Pre workout
1 scoop whey protein

Post workout
2 scoop whey protein

dinner
rice-chicken breast and vege

Pre bedtime
1 glass of milk

Am i taking enough protein and carb to avoid loss of muscle due to the cardio training?

thanks for ur advise jamis. I'm currently 165cm with 52kg, kinda underweight, i do cardio just to cut my belly =(
actually i dont eat that much, for breakfast after the oats with milk i'd feel full already. As for pre workout, i can hardly eat after i took my lunch. Anywhere how many eggs do you suggest to add in my breakfast considering my weight?
