It is a very effective concept, key word concept.. with that being said, I think if you want to incorporate this into your dieting, I would definitely look into some one has vast knowledge and experience with this concept, if you need suggestions, I know of a great guy.

bumping this to get some input, I have been reading about this recently.
Also, to anyone with more knowledge about this concept, would drinking a carb free BCAA drink during the fasting period be counterproductive, or would it be helpful??

If you are going to do the fast, do not injest anything with calories. BCAA's, although incomplete, are protein fractions nonetheless. Albeit slight, they will trigger an insulin release, countering the benefits of the fast.
If you are curious about intermittent fasting, the best thing you can do is try it and see how you feel. Black box it... if you feel and perform better, then press on.
Intermittent fasting is largely dependant on the individual. Some individuals find benefit from it, with progress to show. Others fare better with continuous feedings throughout the day. My personal opinion - not for the performance minded. With fat loss as the goal, things are a little different.
In a quick summary of an experiment conducted years ago - some subjects ate everyday, others ate every other day (1 on/1 off). On the days that the fasted subjects were allowed to eat, their total caloric intake (they were allowed to eat freely) came out to roughly match that of the daily eaters. In other words, after a week, the fasting subjects were doing well with just half the calories. Big time caloric deficit. In regards to performance, you can see how this might not fare so well however. That is just IMO however.
No avenue should go untested. Try it out - you will NOT go "catabolic" and wither if you miss meals. Your body is far more resiliant then you think!

There's no magic tricks here - intermittent fasting is real simple, and its exactly as the name implies. Don't consume foods during the fast. No shortcuts, no secrets.

I'm just saying that there isn't an insulin spike from bcaas alone. Bcaas witrh carbs will enhance the insulin levels. Bcaas alone will not

BCAAs, particularly Leucine, are insulinogenic. Not nearly to the extent of CHO, but they are none-the-less. It is for this reason that they are helpful in re-establishing ketosis in a CKD after a carb-up - they will trigger an insulin response and speed clearance of any remaining CHO in your serum.
As for I.F., I've been employing it for the last 6 weeks or so and thoroughly enjoying it. My performance has not suffered, I've gained vascularity and size and lost some fat. I'm eating primarily slightly over maintenance levels on lifting days, and half that on recovery days. I'm gradually reducing CHO intake, with the intent of going into a regressive keto diet late summer.

As far as intermittent fasting goes, keep in mind that if you eat day 1 normally, then on waking day 2 have say a casein + high fiber breakfast, then eat nothing all day till prebed where you have again some casein and something high fiber you've still done intermittent fasting as you've gone 18 hrs without food, yet its not nearly as horrible as going 36 hours (bedtime day 1 till morning day 3) as far as how it feels.

yeah, I had a feeling the leucine might cause insulin release but I've read varying opinions. I'd like to cut some fat while keeping as much size/strength as possible, but at this point I am really more concerned with the fat loss, as I can get the size/strength back pretty quickly

Have you guys given this a shot? Today was my first IF day. I seriously thought I would be starving all day, but I forced myself to eat about 4:30. Now I am gonna go home a strap on the feedbag
I've been looking over the info on the LeanGains blog - but I am unclear if I break the fast with my prework meal or if it really matters. I usually don't workout until about 7PM but I need to break the fast by about 4 or 5. Any thoughts from somebody who has tried it and what kind of eating split you did 16-5, 19-4 etc.

You want to eat your meal within 1-2 hours of lifting, so as to ensure that the nutrition you have eaten is digested and ready to be put to good use in the gym.
I've been employing a 16-8 fasting-feeding period - trying to cram in 4k kcal in 4 or 5 hours is uncomfortable considering I want to keep it clean. On recovery days I eat about 2000, and that I can consume in 5 or 6 hrs easy.

Staying Hungry is a good idea. I feel that stopping my intake after my post workout meal at 6pm every day and waking to eat at 8am the next day is a good fasting period in and of itself.
