How many ??

No one knows how you eat but you. If you log for a few days you can make your own adjustments that work for you. It's a learning process.

It depends on your goals, and how your body responds to certain foods or what foods your are making available to your self. The more meals you eat through out the day the less hungry you will be, and the higher your metabolism will become. If you are wanting to stay at 1800, consider breaking your allowance into 6 meals/snacks ( 300 each) or 4 meals/snacks (450 each). You should also consider how many calories are burned during your workouts as well. I don't imagine you want to go under 1800, and this can easily be done when you combine calorie restriction AND exercise. SO maybe put your self at eating 2100 calories on work out days, and 1800 on days of rest. You also want to look out what your eating post and pre-workout, and what those workouts entail.. Lots of variables... On days that I hit it hard, I save a good percentage of calories for post-workout, eating very light an hour or so before my workout..
