my use of 'exclusively' in terms of diet should be understood to mean highest percentage and not counting items that are so negligible that the body would hardly recognize them due to the sheer proportion of meat and fat in the diet. When one consumes Anywhere from 70-95% or more of diet as protein and fat anything else is negligible.
Berries are the lowest of glycemic fruits and mixed with fat their carb content is at the most negligible.
