Want to Lose as I work Out

The number of calories you require is based on a number of factors including gender, height, weight, body composition, and activity level, so your question is difficult to answer.

You can use the calorie calculator to get a general idea of how many calories you require, keep a food diary to determine how many you're eating, and then tweak the numbers from there based on the result you're seeing on the scale.
