most certainly not 0gm carb 1 day out!!! Here is from the man himself.. you may need to cut back on the day before and day of to some degree. First 24 hrs of carb loading are most critical

I spoke with jim about this, he told me that would be per day, so whatever your body weight is times 3-4g carbs e-a-c-h day... so yes, you may be taking in over 1kg of dry carbs over the two days... I'm 78kg, so I'll be taking in about 600g of carbs each day following what Jim has set out.
