I've been fortunate enough to read this book and follow TNT as well and I have to agree with everything Roland says. I've never been so relaxed about my eating and find it much easier to stay on track. I rarely crave "bad" foods and I never find myself hungry.
Also, it's convenient. When you're at a restaurant, it's easy to find something that's low carb, but not necessarily low fat.
For me, it's the best way to see results. Eating a little amount of carbs makes me crave a
big amount of carbs, so cutting them out all together is the way to go for me. Like Roland said, the book makes it easy to jump right in, so for those of us with little patience, it's great!
