When you're trying to lose weight or trying to improve your eating habits, a diet diary (or food journal) can be a helpful tool. I wondered if That's Fit readers keep a diet diary. Here's what you said:

• 46 percent of you keep a diet diary every day. Whether you're trying to lose weight or not, a diet diary is a great way to make sure you're keeping on track with your healthy eating goals. Reader jmparlan said, "Right now I am using a diet diary every day. It has helped me lose 40 pounds in 25 weeks."
  
• 19 percent of you will keep track of your eating habits for a few days. This isn't a bad way to go. Even if you only track your eating for three or four days here and there, it can be enough to give you a reality check.
• 19 percent of you have tried keeping a journal, but never kept it up. A diet diary isn't an assignment with a due date, it's merely a tool that can help you get a handle on your eating. Even if you haven't kept up journaling in the past, give it a try. You may find patterns in your eating habits and be able to make improvements.
• 16 percent of you don't keep a diet diary. If you want to give it a try, check out AOL Health's online diet diary -- it's convenient and easy to use.
