Well, many very low carb veggies have plenty of fiber. Dr Atkins talks about this under the constipation question , which can result when initiating the diet.

pumpkin....high fiber, makes great cheesecake
broccalli
radishes
olives
and the list goes on.

Do you include veggies ?? No offense meant, many are choosing no veggies as part of their eating program. Dr A recommends eating 3 cups a day from an allowable list.Two of lettuce and one of green beans or another.

Hope that helps.
