You only really have protein sources every other meal. When I make up a diet plan, every meal starts with a protein source ( lean protein mostly). You should take the number of meals you're going to have and divide the total required protein for the day by that number.

You should be getting at a bare minimum 1g protein per lb of body weight. I would reccomend more if you can. Otherwise, if you're losing weight it may in fact be partially muscle mass...not cool.

Well thats all I got for now.
