I've been wondering this, over the past couple of days, too, even though I'm a SW veteran and I know it's not true! I've been feeling really bloated and sluggish over the past week (blessed * week) and I have been wondering if it's due to the amount of pasta and potatoes I've been eating.
I have been eating a lot. I'm talking huge jacket potatoes with entire tins of baked beans on them, massive tubs of pasta salad taken to work, along with 2-3 apples and a couple of yogurts. I work in a residential home where all the food is home-cooked and we have the most delicious cakes and biscuits around all the time, so not eating them is really hard, so the only way I've been able to stop myself so far is to make sure I am full to the brim whenever I am around them!
I keep thinking to myself that if I was to eat more salad and vegetables then maybe I would have lost some more weight this week (at the moment, I don't know for sure that I haven't, as I don't weigh till Wednesday, but I've been "checking" at home, and I don't see a loss, although, I'm not sure of the difference between the SW scales and my own, so I know I'm probably upsetting myself over nothing), even though I know I have stuck to the plan 100% this week.
Having recently taken and passed a Nutrition and Health course through work, I know for a fact that carbs are the body's preferred form of energy, so cutting them out is silly. I tried the Atkins diet for three days once and lost about 10lbs (yes, really!), but as soon as I started eating normally again, it all went back on again.
I'm not really sure what the point of this post was, but I just wanted to echo the feelings of the post at the top, worrying about the amount of carby stuff one eats, even though there's nothing to worry about.
