This is my first day of trying this out, and so far, I love it...
I initially figured it was either quackery or a money-making gimmick, but after reading up on the WD on bodybuilding.com and checking out some posts from bodybuilders who eat similarly, I decided to give it a shot.
So far today, I've had only water, coffee, some whey protein, and fruit, and I feel incredible. I normally do the usual bodybuilding 7-8 meals a day, am never hungry (I'm usually force-feeding myself all day), and constantly having my energy levels going up and down- from lots of energy to total crash several times a day. Today it's been a steady day of feeling great, and my mood in general feels better than usual. I'm looking forward to eating a big meal tonight and going to sleep afterward, which is what I always want to do after eating (and wreaks havoc with my productivity if eating 6-8 times a day).
The only thing I'm worried about is going in the gym this week (I lift weights 3 days a week currently) and getting my butt kicked by much less weight than I'm used to from an overall lack of carbs/calories. I"m not sure if this will occur or not (I like to have an apple and a scoop of whey pre-workout, which seems to fuel me pretty well and would fit with the WD just fine).
Not spending half of the day wishing I were asleep, or feeling like a zombie is amazing though! So far, I really like it.
Edit- It'll be nice to see if I can lean out a little from this while still at least maintaining my muscle mass and strength. I'm 5'10 and weigh about 220lbs not bad for someone who started out as a 145lb weakling

), mainly muscle but I do have a little gut from "bulking" as well- I think it's mainly excess water but there's definitely some fat there as well. I'd guess I'm at about 15-16% bodyfat right now but not totally sure.
