Just a few nit-picks:<p>Dietary fiber (at least fermentable poly&#x2F;oligosaccharides), while technically a form of carbohydrate, is fermented to short chain fatty acids by the bacteria in your gut.  These short chain fatty acids have some fairly special physiological effects that you can&#x27;t get from other macronutrients.  For this reason, from a health perspective it does make sense to treat fermentable fibers as a separate category of nutrient, and set an intake target for it.<p>Also, lactate is the preferred fuel for your brain; it has been shown that if lactate is available glucose uptake by the brain is _greatly_ diminished.  In fact, a major role of astrocytes in the brain is the metabolism of glucose to lactate for primary neurons.<p>As for the 5% protein number, for starters that is meaningless without knowing the number of calories being consumed.  If someone was somehow active enough to burn 10K calories a day 5% protein might be a reasonable amount.  For your typical 2K cal&#x2F;day diet, however, that number is woefully inadequate.  0.8g&#x2F;Kg&#x2F;day is the minimum anyone should reasonably be getting, and even non-exercising populations will tend to be leaner and feel better around 1.2g&#x2F;Kg&#x2F;day, not to mention athletes who will do best around 1.7g&#x2F;Kg&#x2F;day.
