If you want to lose weight when eating out, you should ask for half portions even before the food arrives at your table. This really makes your healthy weight loss efforts count, as you won't be tempted to overeat. But what about situations where you are unable to get half portions, or it's inappropriate or difficult to request them? Situations like attending a business conference where you don't want to take home leftovers or a fine dining restaurant where it's not polite to ask for a doggie bag? Healthy weight loss is important, but so are social graces.
