Curtis Harwell Discusses Why are You Afraid Of Carbohydrates?

As far as the amount of carbohydrates your body requires, this will vary from person to person depending on a number of things (age, weight, height, body type, activity level, job, sleep etc).  As far as eliminating them completely, whether in a bulking, fat loss, sports conditioning phase I would NEVER do that.  Carbohydrates are essentially your bodies primary source of fuel, if you restrict carbohydrates for a long duration(2-3+) there is an immense possibility for your body to enter a catabolic state, meaning your muscle cells have been depleted of glycogen, and you are tapping into your muscle storage for energy.

One method to work with is carbohydrate cycling, this is when you lower your carb intake for up to 2-3 days MAX and then refeed again after that to maintain an anabolic state(hypertrophy and fat loss).

Personally I do not carb cycle anymore, I utilzing a method called "carbohydrate timing", where you eat a large amount of carbs at the correct time of the day(morning, pre workout, post workout) rather then at night or other times during the day where it is not required and may be stored as fat.
