All foods can be part of a healthy diet, if you eat them in the right amounts. But many of us don't know how big a single serving is — and the rest of us still "super size" it instead of sticking to a reasonable portion. How often is your chicken dish just 3 ounces (the size of a deck of cards) or your cereal bowl filled with just 1 cup? Try these tips to get servings down to size:
Measure out proper portions for one week to learn what the serving size looks like.
Dish out meals and snacks in single serve containers before storing them in the pantry, fridge or freezer.
Spend a little extra on pre-measured foods if that technique helps you eat less; it won't cost more in the end because you'd have finished the box faster the old way.
At restaurants, when the mega-plate arrives, immediately cut it in half and ask the waiter to bring a second plate, and put it aside, or better yet have the waiter put it in a doggie bag at the start of the meal, so you're not tempted by it.
