Anyone who has ever attempted weight loss has also attempted to find some way to boost or speed up the rate at which they burn calories.  Metabolism, defined as the sum of all physical and chemical changes taking place in living cells in order to maintain life, can either make or break our ability to be successful at weight loss. Think of your body like an engine with your metabolism the rate at which your engine runs.  By making a few adjustments, you can cause your engine to rev up a little higher burning a few extra calories.
