This is the easiest way to lose body fat while preserving muscle and health that I know of. In this video I give a basic explanation of of how to do it and some why's and some dont's.
Don't think of this as a diet! diets SUCK and don't work long term because of it.
For more information about some of the things I mention in this video search : Cyclical ketogenic diet, Benefits of fasting, Bulletproof diet, Slow Carb Diet, Hormonal response to sugars.
