Am I eating enough?

Hello! I'm new to dieting & calorie counting & just started my second week. I dropped about 2 lbs in the first week by exercising & using this app (eye opening!). Have a quick question: if my daily recommended caloric intake is 1400 (per CC app) & I burn add'l 500 calories by exercising; a) I CAN eat at least 1900 cals that day to lose weight;  or  b) I MUST eat 1900 cals that day? I do believe I need to boost my metabolism & in the past I haven't been able to lose weight due to not eating enough. Thanks for the help!
