I haven't tried the one-day weekly fasts, but earlier this year I did a 7-day water fast (i.e. you eat nothing and you drink nothing but water). This was primarily for cleansing, rejuvenation, and curiosity. I was doing the 5x5 StrongLift regimen for a few months previous to the fast, and continued after the fast.
I'm also a strict vegan with an emphasis on raw fruits/veg/nuts/seeds, although I still eat cooked foods occasionally. The reason I mention this is because I've heard that if you're a carnivore, or heavy into dairy, soy, processed food, or junk/fast foods, the effects of the fast can be more severe (i.e. more intensified cleansing crises, which are things like headaches, breakouts, pains, etc.), but I didn't have any particular difficulties like those other than lack of energy.
Anyway, during the fast I did nothing (no cardio, no walking, no lifting), and just did things around the house (I didn't have to work or drive anywhere, so I basically stayed home for a week). [And if you want to try this type of fast, I hope you're able to take a week off at work, otherwise, it may be risky.] The first day or two was tough (i.e. battling the hunger/cravings/etc.), but from the next day on, I didn't have any hunger/cravings, or even the desire to think about food, let alone eat it. After about 3 days, the effects of the fast kicked in because I was much weaker and had little energy. This continued up through the 7th day and by then I was like a zombie, just low on energy, and slept when I felt like it.
I've heard that the first extended fast is the worst, and that they get easier if you continue to do them. I hope to be trying another one (perhaps 5-day or more) sometime soon. It's a logistical concern, because you have to be sure you have no obligations (like to drive, or do anything basically for that period), and thus it takes some planning. Fasts should be prepared for (nutritionally), and you should read up on it before and during the fast. There are a bunch of useful books out there. If you have a lot of things you need to do/organize/clean around the house, it's perfect, and you don't realize how much time (out of a day) eating can take (driving/shopping, preparing/cooking, storing, cleaning, etc.) until you don't do it for a while! One book saw fasting as a form of time management.
The effects of the fast included both fat and muscle loss. I lost a lot of fat (there wasn't too much to begin with, but what was there was nearly gone), and some muscle. I was weak most of the time and did not do any strenuous activity. [Forgot to mention that on the first day of the fast, I was moving tons of very heavy boxes for about an hour or so, and thus did do quite a lot of strenuous activity, but after that day, no more.] I was a bit worried about muscle loss during the fast, but decided to try it anyway. When I got off the fast, after a few days of easing foods back into the system, I took it easier at the gym and didn't want to overdo anything. I was very pleased to notice that it only took about 2 weeks (2-3 sessions per week) to surpass what I was doing before the fast, and that was just because I wanted to ease back in gradually. I could have pushed/rushed it, but chose not to.
I'm not making any health claims, nor do I recommend that anyone do what I did. I also don't really think it's a good idea to associate/link (extended) fasting with weight lifting. The reason I did the fast had NOTHING to do with lifting, or losing weight, or anything. It was purely a cleansing/rejuvenative experiment that I plan on doing at least 2X per year, possibly more. Hope this helps anyone interested in this type of fast. Please don't do it unless you have a pretty decent idea of what you're doing, I WOULD NOT recommend this just anyone. Also, if during the fasting period you have to drive, or do anything like intensive work/study, etc. DO NOT attempt this type of fast! (You can still drive after the first day or so, but after that, it would be very risky.)
