Most of us have a hard time drinking all of our water, so I thought I would add something that helps me with the motivation to drink more water.
When I first started doing this diet, I did a lot of internet research, and one thing I read (which I think is also in the FAQ section) was that it works because when you are in ketosis, you are literally peeing out your calories!
No water = No pee = Calories waiting to come out!
So Drink Drink Drink!!!
(hope that helps)
