I've just gone from 199-189 in roughly a week and a half and I can't tell if its strictly water weight or what not
A little of everything, well more than 1/2 water weight, and some fat and muscle.
Eat at least three times a day
make sure that every meal provides a good amount of protein and carbs
No protein and fats, any concentration of carbs you want before and after exercising.
Changing habits like eating aren't a night and day thing, accept the fact that you may crave certain things and feed those cravings even if they aren't good for you.
No, quote from my tips sticky:
Defeat the cravings, don't allow youself to eat the fatty processed foods your body desires. Get yourself some sweet fruits and vegetables and munch on those until the cravings subside.
but I'm only eating like 800 a day IF
I don't know what your basing that off of but you have your metabolism in a slump right now. Your diet by the sounds of it needs an overhaul. Give an example of what you typically eat throughout a day.
