How many calories a day should i eat to permanently lose weight?

i wake up at 11 and eat toast w/ a little bit of peanut er on it and around 5 or 6 i have a bowl of raisen bran or a pb&j sandwich, i also drink 8 full gles of water EVERY day....so is this good? btw i'm almost never hungry throughout the day and have lost about 35 lbs with it so far
