Re: Drinking tea as an alternative to water bottles?
A bit confused. What fast are you on? What do you mean by water bottles?
Splenda is poison. If you are on waterfast, you should not be consuming anything but water. You should not be consuming caffeinated drinks on a fast. Although i sympathise, as caffeine is my achilles heel. If i could drink tea and coffee on a fast, i'd have no trouble with doing it. With tea and coffee, also comes milk, and if you sweeten it, it is becoming less and less of a true fast.
People go into ketosis eating protein, not that i advocate that, so i'm not sure if it will take you out of ketosis or not.
The danger is, if it does, it becomes a starvation diet not a fast. Although Mastercleanse, drink lemon and maple syrup, so who knows what harm it would do, but the point is, you are supposed to be cleansing and taking caffiene is going against what you are trying to do. If it is mainly for weight loss, and it helps you, you will have to be the judge if it is worth the risk.
