This is my first week and so this is how I've started:
1. Label 3 1 gallon baggies Breakfast, Lunch, and Snack
2. Breakfasts are all drink mixes.
3. Lunches are soups.
4. Snacks are bars or crisps. I eat restricted IP items only as snacks.
I put seven of each in the appropriate bag and store them in a bowl in a cabinet that I usually don't need to go into except when it is time to pull out a packet. That's my IP food for the week.
I started out with 10 boxes of IP foods. I store the remainder of the packets in their boxes in a pantry unit in my garage. I don't need to see them again until it's time to refill the bags. I can see what I will need to shop for at that time.
I chose to do it this way so I would have to think to much about what I was doing and wouldn't start obsessing about what to choose.
I really like this system so far but I am just finishing my first week.
