I've been on a low GI diet for just over 3weeks. I've lost 11lbs. My moods have stabilised and so have my cravings and binge eating. My Doctor (enviromental health specialst amongst other things) pushed me into it and I would now swear by it.
Basically, follow your calorie count keeping bad sugars and carbs out. I've swapped fluffy pasta and rice for bulgar wheat or couscous. Swapped thick cut white bread for soya bread. Mars bars have been replaced with green and blacks organic 70% dark chocolate. I've lowered my tea intake by introducing white strawberry tea (gorgeous) and water. I've stopped buying processed foods and mainly eat bowls of stirfried veg for dinner.
I would swear by green tea and I did drink it for the first 2weeks, but just got to the point where I couldn't stand the bitter aftertaste any longer. The white tea is meant to be purer and therefore has a stronger detoxifying effect. But, there's one big positive, it's actually nice!
Anyway, it's well worth a go, I personally found the Atkins too restrictive and because I couldn't stick to it ended up putting on 3lbs. Simply wasn't my way of eating. Low Gi suits me. I've also got the hubby ad kid on it, I hope my kids never have to bother with trying to change their eating patterns...
GOOD LUCK
