Fasting- no caloric intake. You can drink water and non-caloric beverages like black coffee. The benefit comes from not taking in any calories, not dehydrating yourself.

I know some religious fasts prohibit drinking, like on Yom Kippur you're not even supposed to drink water during the fast. But that's different.

Hydration rocks. The number of over hydrated humans reading this is quite small. If you consume coffee and/or alcohol regularly, your kidneys may appreciate an agua break. Pee clear. As a regular practice.

The following are acceptable to me when I IF:

• water, sometimes weak lemon or lime water
• seltzer, flavored or plain
• tea (black/green/mate/red/herbal), no sweetener and no creamers; can be hot or iced
  • lemon in iced tea is ok
• coffee, no sweetener and no creamers (this is rare -- usually has to be cafe americano)

Dr. Eades has written about the benefits of drinking extra water for fat burning. His conjecture is that thinning the blood reduces the concentration of insulin in the blood, which gives a slight boost to fat cells' rate of expelling fatty acids. However, even non caloric sweeteners cause a psychosomatic insulin release which makes me miserable and shuts off the gravy train of FFAs. That's why sweetened tea/coffee and sodas are off limits. I've helped myself adjust to this by not drinking my tea or coffee sweetened even when I'm not fasting, and eliminating soda from my diet.

Fasting is stressful enough on the body. There is no reason to also be dehydrated.

Yes. Whenever I'm thirsty. No need to measure it out.

When I IF I drink water and herbal teas. Lots of them. I see no reason not to. It keeps me hydrated and my mouth somewhat happy and occupied.

When I IF it's great for me to get some sort of flavor in my mouth so what I like to is mix half soda water and organic lemon juice. Suppreses the appetite and it seems to flush out my system pretty effectively.

I know that's not 100% orthodox paleo, 'cause I doubt cave man were running around with Big Gulps of carbonated beverages but its my own personal preference when I'm on a fast.

I'll drink plenty of water, and maybe some green tea or black coffee

Yes water for sure.

I regularly water fast for 2-4 weeks each spring. I experience mini Al weight loss. Remain overweight bur otherwise no overt health problems ( no diabetes, no htn , chilesterol ok, no pain).
