"Stored triglycerides" refers to excess fat that your body saves for future energy use.
Full definition
The main way to do this is to store glycogen in the liver (stored sugar) and then to
store triglycerides in fat tissue.
While some would worry about gaining weight from adding saturated fat to their diets, the book reminds: «Scientific studies have reported that the fatty acids from MCTS in coconut oil are not easily converted
into stored triglycerides, and that MCTs can not readily be used by the body to make larger fat molecules.»
Leptin, as I mentioned, is produced by the adipose tissue, and adipose tissue is where
we store our triglyceride or dietary fat, or endogenously - synthesized fat.
The ketones are
stored triglyceride and broken down into fatty acids used for energy.
If you diet in an intelligent way you'll force
the stored triglyceride in your fat cells to separate from the free fatty acids, leaving them to travel to the parts of the cell that can burn them up for energy.
The extra calories that are needed for muscle growth will come from
your stored triglycerides.
