A 0 carb diet would definetly be boring. You couldn't have any veggies, so no fiber and very little nutrients. Als ono eggs, shell fish, coffee, artificial sweetners, processed meats, or convience foods.

Basically all you could eat would be fats, meat in a natural state, and that's about it. It doesn't sound like soemthing that can be kept up for long without health concenquences.
