Facts are a work in progress. There will always be new data providing new insight into details we were previously unaware of. The new conclusions we draw from the data (new and old combined) allows us to use that data for making decisions in our life, such as how to eat. The data by itself tells us nothing and leaves us with no guidance until we interpret it and test that interpretation for ourselves. When new data changes our interpretation, the old data is still valid; the new data has simply been added to it. The previous data is still fact, and new data is new facts to add to the old ones.

If the model does not work, we go back to the data to see if we missed something, and researchers go back to the lab to collect more data to fill a gap in the model, sometimes recording data that uncovers the possibility of a completely new model.

Under-feeding your exercise eats up muscle published by drclyde on August 6, 2012 – 10:16pm Glycogen is the storage form of glucose in cells, with most of it in our liver and muscle. When glycogen is low (see figure B, from reference 1), there is an increase in adrenalin (to increase fat availability), cortisol (to break down muscle), and an increase in the rate of sugar uptake into cells. The opposites are true when glycogen in muscle is full (figure A). Cortisol and other signaling pathways lead to a loss of about 40 Calories worth of muscle protein during...
