Browsing the last couple pages, watching the videos and whatnot, the gist of this theory is like (and I might be completely off here. Apologies if this is all ignorant.):
Carb nite is to lose weight (and maintain strength?). Low carb 6 days a week; on day 7 eat high carb towards the end of the day. Repeat.
Carb back-load is for strength and leaning out if you're already in shape. Day before workout eat high card towards the end of the day. Otherwise, keep a low carb diet.
The 'eating high carb food' part isn't just a single meal, but stretched throughout the evening. A bit confused about what foods are better, and the volume you're supposed to eat. Sugary foods (candies, certain fruits), certain vegetables, desert foods (like brownies, ice cream...vague category), or pasta, rice and breads? do you just go mad on it and gorge, or do you have a slice of pizza or two bananas or something?
