Worried about my calorie intake?

you have not eaten ENOUGH today. With the amount of exercise you do, you need to take in about 2000 calories, and you've only taken in about 900 (including what you'll have for dinner). After the exercise, you'll be at about 1500 calories, which is a little enough amount to cause you to lose weight (if that's what you're wanting to do). a deficit of 500 calories/day is enough to cause a 2lb loss per week, which is the most you should lose per week.
