I know how to find my own caloric maintenance for cutting, maintaining and bulking.. However I am in the dark on how to calculate this for a women since she does not really lift weights. If it helps here is a background: my g/f is already skinny and has a good body. She is about 5' 4" and weighs 115lbs. She does not really want to cut down much fat (there isn't much to get ride of) BUT she is a brides-maid in her cousins wedding and of course she wants to looks as great at possible and wants to cut down like 5lbs and maybe 1% of b/f or so. Problem is that I have no freaking clue what her maintenance would be. Currently her diet ranges quite a bit. One day she will eat well and only take in about 1200 cals, another day she will take in 2000. My best guess was the find a median and have her try and keep her cal intake consistant at 1400 (not sure if that's too low though). She is pretty active (goes to the gym 4X a week and does some light lifting for ~ 30min and then another 30-40min of cardio. Should I just tell her to watch what she eats more consistantly or should there be a specific cal # for her to follow? Thanks for any help. My knowledge of cal maintenance is limited to that of the male gender.
