Guest guest Posted April 13, 2005 Report Share Posted April 13, 2005 Does anybody takes in mind fiber calories when counting them for CR purposes? Although there is ongoing debate in this area, a caloric value of 1.5- 2 cal/gram for fiber is the currently accepted value (being the soluble kind the more caloric) which are absorbed from gut (mainly colon) once bacteria living there have metabolized it into SCFA, such as acetate (used for building fats), propionate (used for gluconeogenic purposes) and butyrate (main food for colonocites).. Even then, since a fiber intake for most people these days probably doesn't top 25 grams/day, that's only about 35-50 calories total per day. A massive 100 grams of fiber/day (I easily reach values of 60-70 grams a day) would yield >150 kcalories, what would be significan; thus you may be adding about 10% more calories from those calculated just from fats, proteins or carbs. This turns fiber to a fourth macronutrient by its own, isn't it?!
