In the comments after chapter (10), Carly, talked about the importance of knowing the difference between being hungry and being thirsty. She said "I have also noticed how sometimes you need to pay attention to your body when it comes to fluids as well. When your hungry, really ask yourself if you are hungry or thirsty. I usually get a glass of water and drink it. If I'm still hungry in 10 minutes then I eat something. Drink Water! Your body needs it."
This is an important point. Determining if you are hungry or just thirsty can be tricky. If you're craving wet foods your body may be thirsty. If you drink a lot of soda or caffeine (which is a diuretic), your body may be mildly dehydrated. Drink small amounts of water all throughout the day.
