In the years I have been writing this blog, the single most important concept I have run across is Portion Control.
You have to get a handle on how much you are putting into your stomach if you want to have a chance at good nutrition and good health. The perfect partner to Portion Control is Serving Size. When you look at a snack package and read “150 calories per serving,” don’t get excited about eating it until you know how many servings are in it. If there are four servings in the package you need to realize that eating the whole package is a 600 calorie snack, not a 150 calorie one.
I like the visual examples in the info graphic. A three ounce serving of protein is about the size of a deck of cards.
My Plate also gives a good breakdown of the proper proportions of veggies to fruits, grains, protein and dairy in a healthy diet.
