It forces you to a lot more fresh fruits, vegetables, and whole grains. Plus it doesn't feel like an arbitrary division. Looking back, it seems weird to take fiber out of food. It makes things taste sweeter and extends their shelf lives, but at the cost of complexity of flavor, texture, and nutritional value.
Since avoiding foods with fiber removed, my diet has become more varied, fresh, cheaper, more delicious, and I eat more food. The biggest surprise was that stopping using olive oil, which I had allowed at first, felt natural and I don't miss it. As a result, I eat to stuffed almost every meal.
