Sugar is killing the health of our country. Everything has high fructose corn syrup in it these days. I started the Zone diet about 6 weeks ago and could not feel better. I had zero weight to lose, I just wanted better physical performance. It is crazy what this way of eating will do to/for you. I have dropped around 4-5% body fat but I have not lost a pound. I have kept all my strength and feel amazing.
Try it for a month or two. It will make a huge difference in your quality of life. It does suck at first though. Very litle bread, no pasta or rice and no sugar. All carbs come from fruits and veggies. I truly believe it is they way we were intended to eat.
