One of the best things I learned was easy ways to understand portion sizes, especially when I am not at home or don't have something to measure with. This becomes increasingly helpful at restaurants where the portions they serve are always much larger.
Here are some great ways to visualize what a "real" portion is..
You may know that 3 ounces of steak is a healthy portion, but do you know it looks like?
3 ounces serving of cooked lean beef steak is about the same size as a deck of cards!
Do you really know at a glance how much a half a cup of potato salad is, or a cup of pasta?
A 1 cup serving size is about the same size as a tennis ball!
What about when your making pancakes, do you know how big a pancake serving is?
A 4-inch pancake is about the same size as a compact disc!
Do you pile on the meat when making a sandwich?
A 3-ounce serving of deli-sliced meat like turkey is about the same size as a cassette tape!
Don't be fooled by those extra large restaurant muffins
A regular-sized muffin is about the same size as a cupcake wrapper!
What about those pesky things like Peanut Butter, Mayo or Butter?A teaspoon is about the same size as 1 die!
A tablespoon is about the same size as 3 die!
Having something to visualize will hopefully help you when you determining portion sizes. It also helps to keep you in check with yourself when you know that heaping spoonful of mayo is way more than a single serving!
