Yes, you do. Although I *think* the South Beach Diet is a little lighter on the fats than the Atkins Diet (someone can probably confirm or dispute...). For instance, SBD recommends Canadian Bacon vs. regular bacon because it has lower fat; also, lean meats and fish, eggs, but also egg substitute. The breakfast part was always the hardest for me because the choices are fairly limited, but once I got used to having egg omelets with some Canadian bacon on the side, it wasn't so bad (I add veggies to the omelet). I used to always skip breakfast and be starving by lunch time and then I'd overload on the carbs and crash mid-afternoon. I'm definitely not as hungry during the day with less carbs.
