What is everyones calories needed for good workout?

I know everyone is different with goals and size etc. But I notice that if I don't have at least 1,000+ calories for the day prior to working out I won't have enough energy for a good workout.

Today I prob had 600-700 carries then went to gym at 12noon. I did 20 min of cardio which was fine. Then a crappy back routine due to lack of energy.

I think the higher my calories are for the day the better my workouts are. I just have to remember that and not get discouraged and believe I'm just weak that day.

Anyone else have a calories threshold needed for solid weights workout?

My ideal workout is usually after a proper breakfast, usually atleast 400-500 calories then letting it digest for an hour or two. My workouts are just fine with 100-200 as well though, and even fasted. Recently I've preferred to eat before going though.

I need two solid meals in me prior to gym. if not, gym fatigue. I haven't evaluated that comment since I started getting most of my carbs from whole fruit.
