My Pyramid Tracker (http://www.mypyramidtracker.gov/default.htm) is a free site from the U.S. Department of Agriculture. It analyzes your food intake and makes recommendations based on the 2005 Dietary Guidelines for Americans.
I was testing it to see if I should recommend it to the bloggers when I found out that my pyramid is quite lopsided. The analysis showed that for the last 24 hours my calorie intake was twice as much as my energy expenditure and my grain intake was 273% of the recommended intake. This could make for a very out of shape "pyramid". You may want to check out the link to see how you fare in the world of nutrition.
