I think that a lot of the problem that contrary physicians and other health professionals have with a controlled carbohydrate lifestyle is that they don't understand exactly what it comprises.

For example, Atkins is often touted as an all-meat, low-fiber diet, which is not true.

Most controlled carb programs also stress the value of nutrient-dense "good" carbohydrates which are often lower in carbohydrates than their less nutrient-dense fellows.

The other thing is that the controlled carb "induction" level of carbohydrates is a lot different than the later "maintenance" levels of carbohydrates.

Without supplementation, while I diet, I would be severely deficient in Vitamin C and Folate. However, as I add good carbs for weight maintenance, these numbers tend to rise. Supplementation keeps me on track in the meantime.
