My body does not process carbs as well. I'm insulin resistant so yeah, carbs do matter to me. My doctor has told me that part of my rapid weight gain and struggle with losing is because of how my body processes them.
I'm on a metabolic diet now and am doing 60% protein, 30% carb and 10% fat. I have a structured menu that I'm allowed to eat off of and it is working beautifully. I've lost 10 lbs in 10 days.
And yes, I know it will not continue to drop that rapidly and that SOME of it was water weight but not all of it. I have been eating better (cutting out the crap) since 1/02 (and drinking close to 2-3 liters of water a day) and had only lost 8 lbs. Since starting the metabolic diet on 2/08, I've lost 10 (now drinking 4-5 liters of water a day).
As for cravings... I can honestly say that my desire for sweets has drastically dropped. Whether it will stay away is another matter but for now, I haven't had any cravings and didn't even get tempted when the girl scouts were at the office today. (GO ME!)
Personally, I just believe we each need to find what works for us and stick with it. Low/no carb, low cal, low fat, high protein, whatever. If you're feeling better, eating better and losing weight then it doesn't really matter.
