As someone with extensive experience fasting, some thoughts.<p>> My goal is to get into Ketosis before the water fast begins.<p>This is great, it's much easier to start a fast when you're in ketosis.<p>> I keep my water intake high during the week, attempting to drink between 4-7 litres of water per day.<p>This is way WAY too much water, especially if you're drinking anything on top of it. Shoot for 2.5 to 3.5 liters a day maximum. If you do this for any prolonged period of time, or multiple weeks in a row, you're going to have issues.<p>> This is why the fasting once per week doesn't work for me. I think it is just repetitive torture every week with minimal fat burning and quite a disruption to normal socializing.<p>Yeah, that's because you're doing it wrong. I'm on week 4 of 5/2 (fasting/eating) and it's sustainable. So long as I don't eat pure junk on my 2 days, it's not even that bad for the first 24 hours. I have one friend who maintained this schedule for a year and a half, and another who's been at 96+ hour fasts for over a year now.<p>> Cooking whilst mid-fast is torture<p>I didn't find that to be the case. I cooked for my girlfriend plenty on my 60 day fast. Wasn't that big of a deal. Didn't start until after the 2nd week though, so that may have something to do with it. I guess I can see it on shorter fasts if you're not adapted though.<p>> "Threw some salt in my water, feel a fair bit better after that might do this once a day."<p>Yeah... this individual and I need to have a talk about that. This guy says he's 75kg, drinking 4 to 7kg of water a day, for 3 to 5 days, without _ANY_ salt to speak of. The average human is 55 to 60% water by weight. Do you have any idea how hard that is on your kidneys? Or what it does to your salinity levels?
