I see too problems - too few calories, and you're not eating breakfast soon enough. GOing too long without breakfast will cause muscle breakdown as your body turns to it for fuel. I don't know if you exercise in the morning or when, but it's best to have no more than a half hour of moderately paced exercise, then eat. Don't go much longer.
For calories...it depends on your metabolic rate. Never go less than 10 calories per pound of bodyweight. So for me that's 2020 cals/day. If you're active hat day it should be closer to 12-25 cals/pound. If you're carrying less than 30 pounds of extra fat, and you're losing more than 1-2 pounds a week, you're eating too little calories.
