I was major cranky and getting depressed on Atkins and when I switched to a whole food, real similar to South Beach, I felt a whole lot better. No irritability, migraines, cravings, and losing weight. I am losing weight too.
The glycemic load is discussed in South Beach too. It makes more sense when you factor in the fiber, fat, protein, acidic level, all factors of how fast a food impacts insulin release.
