All meat? Who said that? The foundation of your diet should be produce, healthy fats, and some meat or dairy to taste. Eggs and oatmeal (if you do grains, I dont!) for breakfast, a salad and a side of cheese/nut butter/tuna/chicken for lunch, a steamed veggie/chopped fruit/grilled protein for dinner. Snacks can be cheese, fruit, nuts, hummus, what have you.
Bottled water sounds insane to me, so I don't know which to recommend. I'd just fill up the 1 gallon jugs with the dispenser at the store for arrowhead or whatever the local water is, or buy a Brita pitcher and be done with it. If it is boring, a little lemon juice goes a LONG way.
