Remember how I mentioned that I try to pay attention to what my body needs? Well, I sort of ignored what my body told me when I had breakfast at my brother's house. I had some toast (with a nice heavy whole grain bread) and knew my body needed some protein and planned to have an egg. Not sure why I neglected to have the egg...too busy yacking and visiting I guess.
Then during the drive home (about 5 hours) I had some veggie sticks and a muffin. By this point my body really wanted protein and I ended up with what I call a "carb headache." I get those now and then when I don't have enough protein, even when I eat complex carbs. (When I was eating too many simple carbs of white flour and potato chips--before My Healthy Eating Challenge--I got frequent carb headaches.)
Thankfully I took some medication for my headache and it helped. When I got home, I ate a bowl of cottage cheese and felt much better, physically.
