It's individual. No magic formula. Eat enough to nourish yourself, feel satisfied, and head off cravings (the ones that are for huge amounts of non-nutrient-dense foods). Having excess fat is mostly about hormonal imbalance, metabolic derangement, and/or inflammatory disease - not about CICO. Removing fat is treating just one symptom; the disorder remains and the symptom will come back if you only treat the symptom.
I think Julia Ross' book The Diet Cure is a fantastic overall exploration of health and nutrition.
