Heading out to dinner with a friend, go dutch with what's on your plate! The portion sizes at most restaurants are enough to feed a small army, way too much for a single person. Split a meal, dessert or drink with a friend to help cut those calories in half.
Ignore the temptation of others around you. If you are at a birthday party and someone keeps telling you to eat a small slice, tell them "no, thanks". It's hard when people know that you're trying to lose weight, but you must be firm. If they keep hassling you about this, then avoid being around them if you are able to.
Say you're a condiment lover. You love to slather mayonnaise on your sandwiches. One of many small changes that can save you hundreds of calories over time is to simply use mustard instead of mayo on your next sandwich. Depending on how much mayo you used to use, you could save up to 100 calories from that simple swap.
