- How much kcal shoul I eat if on cutting diet?[/quote]
How intense of a cut are you planning? I’d recommend doing the 12 day break in at 15 x bodyweight, being sure to keep a high fat to protein ratio. Err on the side of more fat in your diet (i.e. 65 - 70%). Do your 48 hour carb load and then try dropping to 12 or 13 x bodyweight during the week.

2. What is the best fiber THINGY that one could eat to be able to shit normally during the carb low days.[/quote]
I have never had any GI issues on this diet. Eat plenty of veggies and nuts. I love almonds, and they provide 3g of fiber per serving. I’ve consumed entire tins of almonds on this diet and was no worse for wear. That’s something like 1800kcal and ~160g of fat! 
Low carb diets, physiologically, are very protein sparing. During the first few weeks I GAINED strength and muscle mass while losing fat. I was coming off a more targeted carb diet (JB/T-Dawg) which keeps glycogen stores at an intermediate level. The supercompensation of the weekends skyrocketed my strength. In one month I increased my x 8 squat by nearly 40lbs.
That said, I did initially lose upper body strength, particularly in my bench press. This seems to be a common occurance that resolves itself over time.

4. Whot supps would be good to include during the cut. I know that I need to stack up on fish oil. Anything else?[/quote]
Something like Power Drive to keep you going during those first four weeks. You’ll make the mistakes everyone else does. Overconsumption of caffeine, too little sleep, not enough veggies, too much junk food. It’s okay. Listen to DH and STICK WITH THIS SHIT 
No doubt this is a very mentally taxing diet when you begin - it’s completely iconoclastic and goes against the grain of every single piece of advice you’ve heard. I highly recommend during those initial weeks, if you’re feeling kinda bogged down, treat yourself to some super tasty treat like buffalo wings.
Even though this diet allows you to be more flexibile in food choice for body comp purposes, you shouldn’t neglect your health. I focus on lots of red meat, buckets of veggies, plenty of monounsaturated fats from nuts and olive oil, and eggs galore. For maximum fat loss (and best use of the carb loads), try to minimize saturated fats. There’s some tangential literature indicating saturates can lead to amplified insulin resistance, and could encourage spill over on the weekends.
Prior to the carb load, I perform a mini fast. I’ll bump my calories up Thursday evening right around my workout, and then fast until I begin my carb load the following day at lunch. This ensures sufficient depletion and gets the carbs to where they need to go.
Also. SLEEP SLEEP SLEEP SLEEP SLEEP! On a carb based diet I used to be able to function, albeit somewhat poorly, on something like 5 - 6 hours of sleep. I cannot swing that on this diet. I need atleast 8 hours of sleep minimum, and preferably 9 - 10 hours. I find my sleep patterns are far more regular rocking the AD, and dreams more vivid.
I hope all this helped. Welcome to the club
