Holding Steady

So, I have lost 0 lbs. since last Wed. However, I haven't been exactly faithful to my diet. I have cut back my portions but I did eat bread and pasta, so there you have it. I swam 30 laps today and did 30 diving board pull ups. I am also finding that my body can handle small deviations from the diet but not big ones. I can have a small plate of spaghetti and be fine but if I eat a hamburger I feel groggy and sick. I am trying to remember that when I have a craving.
