Nope, you're not giving your digestion a rest with the apple fast. There's just something about the stuff in apples that draws out the toxins - that's why you should always eat apples by themselves, on an empty stomach, away from other foods (they don't mix well with other foods and take the nutrients away??).
The Apple Fast is just an amazing detox. Did you read the 'R' post below? It has some quotes...
