I pretty exclusively go with FBC style cooking.I have kept track of the weights for all of my trips for the last 3 years. You should be able to get by with between 1.4# and 1.6# of food per day. For breakfasts I have a mixture of oatmeal, pecans, brown sugar,Nido and dried fruit. Depending on your appetite 5-6 oz bagged weight should do the trick. Oh yeah, my Via also. For lunches and snacks I use a combo of gorp, jerky, dried fruit, an energy goo, and home made bars. For dinners almost anything you cook can be dehydrated and used. I need 5 1/2 oz - 6 oz dried for dinner and also have a bag of tea and some chocolate for dessert. On trips of more than 6 days I find that I have to increase my daily food intake after day 5. I don't know what freeze dried weighs per day but I do know that it is expensive, high in sodium and tastes like s--t. I use some of the Food Mavens recipes and others I have come across. If you are interested PM me.
