Fasting is really bad for you. Does fasting even count as hacking?
Research suggests there are major health benefits to caloric restriction. Benefits include reduced risks of cancer, cardiovascular diseases, diabetes, insulin resistance, immune disorders, and more generally, the slowing of the aging process, and the potential to increase maximum life span.[3] According to Dr. Mark P. Mattson, chief of the laboratory of neurosciences at the US National Institute on Aging, fasting every other day (intermittent fasting) shows beneficial effects in mice as strong as those of caloric-restriction diets,[4] and a small study conducted on humans at the University of Illinois indicates the same results [5] According to the US National Academy of Sciences, other health benefits include stress resistance, increased insulin sensitivity, reduced morbidity, and increased life span.
The first day-and-a-half was the hardest I felt really hungry. Then suddenly the hunger stopped and I felt great: really alive and full of energy. This feeling remained for the rest of the week.
Originally I had intended to drink fruit juice but it gave me a terrible stomach upset and I switched to water only (although I did have an occasional glass of wine).
Somewhere around day two my fat started to melt and began to coat my mouth and skin. I grew some huge spots (edit: pimples).
Day three I felt a little light-headed at times but was never tired: I had read about the dangers of muscle-loss so I chose to visit the gym each night and was swimming for up to an hour, too.
By day 5 I could have kept going without problem: I'm a big guy and could easily do 40 days without food. I stopped only because I had a family celebration to attend (and I'm not sure my mother would have approved).
I can't say I noticed much in the way of weight loss. I had read that you normally lose about a pound a day (which may have been true). I'd been drinking plenty of liquid so I didn't lose water.
The evening when I went back onto food was also interesting: the food tasted different — more intense and satisfying.
The following days I felt great and had meant to repeat the exercise for a longer period, but as I yet I haven't. No matter what anyone says, that first day-and-a-half does not get any easier.
Some of the reported upsides that I cannot confirm from such a short diet are: your digestive system shuts down very early and so it gets a rest for repair (something that modern humans never manage but ancient humans probably did); your gut flora also gets a chance to die-off a bit and regrow — we are a forest of yeast and bacteria and some people think the occasional prune-and-regrowth is healthy; your fat (especially your internal fat) starts to melt and be burned up as fuel (this is a surprisingly kludgy process: it seems to all go liquid at once all over your body). I can surmise that given a longer period of time it would be beneficial to get rid of the stored fat (and other chemicals stored in it—fat in animals stores feed flavours after-all). There are reports that stopping, clearing out and restarting your digestive/fat/fat storage/liver system can have other surprising health benefits most notably with Type 2 diabetes; there are also reports of benefits to allergies and food intolerances (again I can't verify).
My father has been discussing doing something similar with his doctor in the hope of curing his Type 2 diabetes.
So, in summary, I found the experiment interesting, informative and fun and would recommend it to anyone (with sufficient fat store) who would like to see what it is like (and can get through the initial wall).
If you do: keep exercising so you don't lose muscle; don't eat anything as then you will become hungry again; don't operate heavy machinery (and probably avoid driving) as you do get light headed; don't expect to lose a large amount of weight in such a short amount of time; avoid fruit juice; don't expect your world-view to change or for it to make you a stronger/wiser/more spiritual person; do expect it to give you newfound respect for ancient man and those forced to starve through drought and war.
I tried giving up eating for a week and it was a fascinating experience: if you are curious, try it. It won't kill you and it probably won't harm you unless you are already ill. It gives you an interesting insight into ancient man and how well our bodies are made to cope with hunger and starvation. The first day-and-a-half was the hardest I felt really hungry.

I'm going to jump right into the idea of fasting for 6 days and the unfortunate reality that most people in our field(s) don't. 1. know how to lose weight (really) 2. know how to eat 3. know how to workout Here, if you want to try fasting, which I do recommend, give this a shot. http://www.leangains.com/ or do the Warrior diet (one huge meal a day). A 16/8 fast is great. Heck, I sometimes even do an eat-stop-eat way…
Do you actually believe you're more likely to lose weight eating organic protein?

Fasting has real and proven health benefits. I have heard physicians state that it is the single most benficial thing you can do for your health. From Wikipedia: Research suggests there are major health benefits to caloric restriction. Benefits include reduced risks of cancer, cardiovascular diseases, diabetes, insulin resistance, immune disorders, and more generally, the slowing of the aging process, and the potenti…
During fasting you will lack vital nutrients that cannot be stored by the body. When you end a fast your blood sugar level will sky rocket, which is also bad for you.

Thanks for the interesting read but I'm confused about this statement: "I grew some huge spots." What kind of spots?

I'm about as serious a high-quality protein advocate as probably exists in the leaderboard for this site (neither "organic" nor "grassfed" are particularly important adjectives for me, so much as "local" and "humane"), and I do not understand what this has to do with diet and weight loss. Do you actually believe you're more likely to lose weight eating organic protein?
You are more likely to remain healthy while losing weight eating organic protein.

Fasting when you sleep hardly counts.
True, though there is a reason why breakfast got its name.
