First time I fasted was for a day...thought I was gonna die...most of the battle however is in the mind, considering that your body generally has plenty of body fat stored up to get you through a day. Just be sure to drink plenty of water.
I've been on South Beach for 3 months so I'm adjusted to the hunger factor. I'm ready! Thanks for the water tip.
Well, at such a time, the body expects to run on carbs and the pancreas fires off insulin, which helps to make people hungry, edgy, perhaps headachey, lethargic, etc.
That's why the Atkins Diet works. It gets the insulin levels down, with its reduced carbs -- that takes over a day to kick in. It brings down one's appetite.
