(duration 31:25)In this show we discuss the nature of the controversy about carb consumption among Paleo-style eaters in relation to health and longevity. Some have challenged the idea that Paleo is low-carb as well as the claim that insulin (via excess carbs) is the main culprit in fat gain. So, we explore the nature of insulin once again to dispel the myths surrounding macronutrient calories. The bottom line is that eating fewer grams of carbs per day–thus secreting less insulin–will have positive effects on your fat-burning as well as your long term heath. Perhaps the main misunderstanding, about for instance Gary Taubes’ insulin and fat loss claims, stems from the fact that excess carbs are necessary for fat accumulation, but sometimes not sufficient (depending on your genes). Rigorous scientific investigation is a difficult process, and confirmation bias tends to be an easy process, unfortunately. Keeping tabs on your blood readings is important, especially if you plan on doing an n=1 study on yourself. Needless to say, we’re not in favor of eating 30 bananas a day, or 20 mangos!
