The food pyramid percentages are:
60% calories from carbohydrates
10% calories from protein
30% calories from fat (one-third or less from saturated fats)
Limiting sodium is healthy because of the risk of high blood pressure.
While trying to lose weigh and stay healthy, it's recommended that you eat the lower serving totals. For example the pyramid suggests that you eat 3-5 servings of vegetables per day. When dieting eat 3 or 4 instead of 5.
As time goes on and you keep track, you'll be able to adjust easier to the pyramid. It will take some time of keeping track to see where you need to make adjustments.
Here's another good site that explains it a bit more. http://www.pueblo.gsa.gov/cic_text/f...ramid/main.htm
