When we say no sugar, that means no fruits, juices, agave sryup, honey, and anything sweet. However, if you really try this, eventually will have to eat some sugar or die. Right!? Eventually you will start losing your mind if you don't have any sugar. So what does it mean to have no sugar in the diet?! I'm trying this and it has been helpful, but after a while if I don't have just a little form of sugar, I will start acting absurdly and be extremely fatigued, with terrible eye pain and always thirsty for water. To me, it sounds likea person with undiagnosed diabetes who even though they eat sugar, they can't absorb it. I'm really interested in Dr. Osbornes advice here. Tahnks to everyone, hope to here back.
