Breakdown % for carbs, protein and fat

sommerskins

I am trying to find the best breakdown for eating carbs, protein and fat. I am reading about it and am getting that I should have 50% carbs and 25 and 25 for protein and fat. I have heard that you want the higher percentage to be in the protein you are eating. I am eating a 1250 calorie diet and at times eating back calories and I have played with it recently and now I have a crap load of calories left, but am limited in all other areas. I want to be on an even slope. HELP!
