Proteins, proteins, proteins

Today has been a very bad day. I felf sluggish most of the morning and when I got home, it took every bit of energy I had just to make dinner for my family. Why am I feeling like this? What could be wrong. I had NO proteins for the WHOLE day. I normally eat a 1 egg omelet for breakfast but was running kind of late today and opted to make a protein shake. When I got to work, it didnt taste the way I thought it would, so I tossed it so that means I had no breakfast. Around 11 I had a small bowl of oatmeal. Again, no protein. For a snack, I had half an orange. Notice the pattern? Well because I had no protein for most of the day I decided to have only proteins for dinner. Now I feel miserable. From now on, I will make SURE I have the recommended amount of proteins each day. It really makes a difference.
