if you're hungry, eat. 1400 calories a day is too little for even a small female that's as active as you are. i would first try eating 1800 calories, high protein, lots of fruit and veggies, whole grains, and moderate fat. yep, that low fat crap really doesn't work, plus men need more fat in general than women anyway. if it's high quality fats (olive oil, avocado, fish, lean meats) it shouldn't affect you negatively, just keep you fuller longer. i use a website called sparkpeople to track all this stuff, they take your activity level, weight, etc into account and tell you how many calories you need, it's really helpful.

also, since you're on T, any fat you have or gain will end up in a more male distribution, so you shouldn't have to worry too much about getting more curves if you do end up gaining a bit.
