How much you eat is just as important as what you eat. You want to experience life in the U.S., but don’t feel compelled to pick up bad habits. Stick to the portions you would normally eat. The U.S. is known for its “supersizing”, especially in restaurants. It is OK to ask for a to-go box and take home that food you couldn’t finish at the restaurant.
Also, check food and drink packages to find out what is considered a normal serving. For example a 20 oz. bottle of soda is actually 2 1/2 servings. Many things that are packaged in what appear to be single serving sizes are actually 2 or more portions.
It’s easier to maintain a healthy weight than it is to overeat and have a lot to lose later.
