So right now, for my own personal ACCOUNTABILITY, I have been tracking what I eat each day. At least most days. Sometimes I do miss.  For me, this is my way of forcing me to THINK about the food I am putting into my mouth each and everyday. Forces me to REALIZE the effects that food has on our fitness levels, our energy levels and overall health.  I don't' necessarily watch the calories I eat each day, I watch the type of foods and the quantity.  I personally don't think counting calories is really a necessity if you are eating correctly. Lots of fruits, vegetables, lean meats, good sources of proteins, etc. are the key ingredients.

One nice thing about these tracking sites, I'll list some below, is that depending on your goals or needs you can customize them pretty good. And they all have pretty deep databases of food's and their values.  Some workout programs, such as P90x or Insanity have you stick to certain percentages/ratios of carbs/protein  through out the program.  With these tools, you can adjust it accordingly so you can see how well you are sticking within those goals from your program. You may not follow their routines to the letter, I certainly don't, but it does let you know how you are doing in relationship. 

Anyways, I plan to keep trying to post my daily journal each day, but you can also follow my directly on the site I am using currently at http://www.myfitnesspal.com/food/diary/kprice.

Here are some others that I've seen mentioned, I can't speak to their capabilities yet, but I've read some other reviews that they work pretty similar to myfitnesspal.com.
