Some people journal their thoughts or feelings. I've never been one of those people. I have a lot of random notebooks and notepads around my house because I like to keep lists though. Either a grocery list or to-do list. I have a list going of books I've read. The one journal I use every day, though, is a Food Journal.
I did Weight Watchers years ago and got in the habit of writing down what I'd eaten. I've kept up the practice, especially when I got sick last fall. It was important to see what I was putting into my body to see if something made me feel off or poorly. Another benefit to writing down what you eat is you see a true story about the amount of sugar or junk that you are eating. You don't realize, until you see it in writing sometimes, what you are actually eating or how often you are actually splurging.
I started with a simple spiral - nothing fancy. Just a small spiral lined notebook. Since I used it daily, I stepped up my game and picked up a super cute fitness journal. Not only is there a space for me to log all my food, but I can also write down a daily goal, rate my day (workout/nutrition/mood). And new to me is a place to journal what I am grateful for that day. I've seen "Grateful Journals" and have always wanted to get one but didn't want the clutter of extra books around. Problem solved!
So I challenge you to start your own journal. This is a small change that can reap big benefits. Record your food intake as well as your exercise and mood. See if you can find any connections between your moods and what is going into your body. Or perhaps you have a bad workout and you notice "Hey! I ate a lot of sugar that day."
This is a change that could cost you $0. You probably have a spare notebook or pad of paper laying around your house. What do you have to loose?
