I ate this today, is this ok for losing weight?

Looks good to me :) You make very healthy choices, and i think your exercise is great. If I would make any change, it would be to add a piece of fresh fruit to your breakfast. Eating a healthy, balanced breakfast will help you ward off cravings later in the day. And go ahead and eat the banana. Bananas are good for you, they have a lot of potium. Keep this up, and you should start seeing results in a few weeks tops.
