In any marathon race, setting your pace is all important. If you watch professional marathon runners, they are running at the same pace nearly the entire race: at the beginning, in the middle, and at the finish line. They quickly get up to the speed they know they can maintain, and they just keep at it, mile after mile, and hour after hour. They know the race will be over after a few hours, and they are content that until that time, they will just keep on keeping on.
This is what you must do as well. Set your pace of low-carb eating, a narrow (six-hour) window of eating, and the end of all between-meal snacking, and then just do it, day after day and week after week. Christmas will be here before you know it, and you can look forward to vastly improved blood sugar scores and your A1c score. Until that time, you will just keep putting one foot in front of the other, running the race that is set before you!
