In an interview over at PaleoDiet++, Paul Jaminet comments on the usefulness (or not) of strict low-carbing (emphasis mine):
It is mistaken to think that carbs are inherently harmful, in moderation carbohydrate is nutritious for us. The body’s ability to generate some glucose from amino acids doesn’t change the nutritive value of carbs, because on very low-carb and high-protein diets, only part of the body’s glucose needs are met through gluconeogenesis (manufacture of glucose from protein) and the rest are postponed, under the evolutionary assumption that carb deprivation is temporary and carbs will soon become available. The metabolic and hormonal adaptations that achieve this postponement of glucose utilization are harmful if persisted in for long periods of time. There is another angle to this: carbohydrates only become harmful at low doses in certain pathological conditions. A negative reaction to carbs is diagnostic of these pathologies. Some in the low-carb community assume that if carbs do cause problems, the proper response is to avoid carbs for the rest of one’s life. No, the proper response is to cure the pathology that has made one carb intolerant. There may be a few genetic conditions where no cure is possible, but commonly the problem is a bacterial overgrowth or infection in the gut and it is quite treatable or curable by natural means. There is no good reason for people to be forced to forgo carbs for the rest of their life. Nor is starving the body of carbs likely to generate long-term health.
Reading this, you might guess that Paul is a 30 bananas kind of guy. But no, the Perfect Health Diet is actually a lower carb diet. In fact, Paul sometimes refers to PHD as a “low-carb” diet … it certainly is compared to SAD (usually in the 150g/day ballpark).
You’re mileage may vary, but I suspect that if you’re on the fence re carbs, you’re probably better off worrying more about the quality of them rather than the quantity of them. Getting rid of processed foods high in refined flour and sugar will probably naturally reduce your carbs.
Standard caveat: if low-carbing works for you, mad props!
