Eating Out, Mexican Style:

With the fast pace and competitiveness of American society, dining out is a way of life for many people. Americans eat out an average of three to four meals a week. Unfortunately, in many cases, restaurant food often contains a lot of fat, sugar and sodium for taste and preservative value. It is possible, however, to eat healthy and choose wisely if you're skilled at special ordering and knowledgeable about food preparation for different cuisines.
Tips:
Hold or limit guacamole and sour cream. Two tablespoons of guacamole has about 50 calories and four grams of fat (72 percent fat) and two tablespoons of sour cream have 45 calories and five grams of fat (100 percent fat).
Hold or limit the chips. A typical basket of chips contains 1,040 calories and 43 percent fat.
Hold the cheese or get it on the side. A one-inch cube of cheese has about 100 calories and eight grams of fat (75-percent fat).
Skip or limit the chile con queso dip. One cup has about 529 calories and 31 grams of fat (53 percent fat).
Drink light beer or a wine spritzer instead of a margarita (90-100 calories versus 250 calories for the margarita).
Split orders and take home half in a doggie bag. Share the praline or sopapilla, if you must indulge.
