Hola again....
the worst thing you can do to your body is drastically limit the amount of food (nutrients, vitamins, etc) in your diet. If anything, eating small meals every 3 hours or so will boost your metabolism, so that it burns more efficiently. Go to the TOOLS and Calculators section and figure out your BMR (basal metabolic rate) or just plug in the following info in the Harris-Benedict Equation. (Just google it.) Read stickied threads to learn more on figuring out how many calories you should be eating. If you start your calories too low for your weight, it'll be even more difficult for you to lose towards the end since there won't be much of a calorie deficit that can be done.
