GB, that is the way i am looking at it, as fuel. no way i could go run 6+ miles on an empty stomach in the morning and get a good workout. my muscles and body would want to shut down and cramp up. i would love to utilize the fat loss, but my training would suffer badly as a result of not having enough energy. and yes, it would be tough to stomach 2000 cals in a few hours, unless it was full of useless nutrition like fast food or something.

Well, I may soon be giving a first hand account. Leangains has you taking 10g BCAA's prior to your workout. Hardly a meal, but it will help with regards to muscle breakdown.

while that is true, what will be your fuel for your workouts? yesterdays 2000cal dinner? having a hard time seeing how the body will react to not having readily carbs there to burn as fuel during workouts. i am doing endurance workouts, so i do not think i could benefit from this type of dieting. if i were only bodybuilding/powerlifting, maybe. i understand the fact of getting all your macros/nutrients for the day, but in two meals? i get really shaky when i happen to skip a meal.

early last week, there were some articles referring to insulin. what kind of effect would this diet have on insulin?

To answer your first question - bodyfat would be the primary fuel source. Since the workout will come at around the 17 hour mark (into the fast), bodyfat will play a key role here. According to the articles, bodyfat becomes more readily available within the 11-18 hour window (optimal fat burning time). I agree that you probably will not feel that 'surge' like you do when having a big carb meal right before. But think of a CKD diet - you're getting NO carbs at all with the exception of a 1 day refeed.

Insulin will obviously skyrocket with the 1st meal after the fast as it will be extremely low. This of course will come PWO when you're in a very anabolic environment. You really need to read the articles if you want to understand this as i'm not doing it much justice with my explanation.
