In a short while, there’s coal everywhere, stacked to the ceiling. He can barely move. He can’t shovel any more coal onto the fire because there is so much in the way. The train stops, and people get angry. At the end of the day, he quits, his dream sabotaged. Mitochondria feel the same way when we give them more glucose than they need. They can burn only as much glucose as the cell needs for energy, not more. When we spike, we deliver glucose to our cells too quickly. The speed – or velocity – at which it is delivered is the issue. Too much at once, and problems pile up.
