The LLCs are a fiber drink because most of us don't get nearly enough. If you PROMISE on a stack of FF books that you will faithfully get your 2 daily TBSP of ground flaxseed in daily by putting in smoothie or on salads or over eggs, etc., you do not have to put GFS in your long life cocktail.
Understand, however, that the morning LLC is the intestinal "scrub" and the hot lemon water is the "rinse" (by way of explaining why it was set up that way). You get the biggest um...BM for you buck, so to speak, doing it this way.
HTH!
