Dry dog food is far better than canned! It is more economical, takes up less space, and is generally better tasting. With reconstituted dried milk (and sugar if you like) most dry food tastes not too different from dry breakfast cereal. A hundred pound sack of dry dog food contains as many calories as a ton of fresh potatoes. The dog food also contains protein, vitamins, etc., that the potatoes do not.

Our understanding of the rubber bag has led us to an effective tool that accurately indicates whether too much, too little, or just the right amount of food is going in. In the last chapter you've learned how to work that tool, integrating it into your daily and monthly routine so the information it yields can guide your eating.
All the information in the world, however, doesn't change a thing until somebody takes action based upon it. In losing weight, ``somebody'' is your body. Now we'll turn to planning meals to control the calories that go in. Analysis of the trend based on daily weight measurements is the key engineering trick to weight control. Meal planning for predictable calorie intake is the central management tool which closes the circle and achieves control over weight.
