Doing cardio is not working for my tummy?

I’ve been doing cardio everyday and I see no difference. I don’t eat junk food but some juices and water mainly. For breakfast yogurt eggs pancakes or oatmeal. Drink lemon with water. Sometimes snack in a fruit like a banana or strawberry. Lunch it depends can be rice with a red meat and some beans. Dinner same as lunch.
