-With these behind us, I'd like to channel [Galileo in the face of the inquisition](https://en.wikipedia.org/wiki/Galileo_affair): evolution has been hard at work for over 2 billion years shaping the chemistry of all eukaryotes, multi-cellular life and eventually mammals. The Krebs cycle, glucose metabolism, insulin spikes, glycogen in the liver, carnitine, lipase, are as real for you as they are for me. We may be very different in our genes and traits, some are more insulin resistant, for example, but we cannot be too different in our most fundamental metabolic chemistry. The chemistry which drives fat synthesis and break-up.
