Micro versus macro What Can Nutrition Do For You In An Energy Balance? Managing one's weight and body composition will require an understanding of nutrition. Nutrition, coined in the early 1900s, refers to the intake of food in relation to dietary energy. But that table under biomass [energy in enormous amounts] also mentions several components, and that web, of biosphere-2 at the sub-stituted sea-level, above, is dazzlingly complex, and punctuated with energy flows everywhere. So, how does one talk about nutrition without talking in calories. So, how does one talk about nutrition without talking calories on one end, and micro nutrients [a wild spectrum from iron, chloride or silica] on the other end. In broader terms, how does one see or conceptualize nutrition. So in terms of nouns versus verbs. So practice might trump concepts premised on dream factions. Perhaps she has a point in saying that we must grasps the practicality first rather than the movie script. So to put the micro into the context of energy intensive practice, that would entail maximally straining the body without actually breaking down muscle. A sub theme here should be about energy output and the energy balance equation. I would anticipate that these factors would predominately account for the final energy balance. Of which low energy availability over a long period of time increases the risk of fracture in both males and females.
