4. Try to plan ahead what are you going to eat at the restaurant. This might sound like an unnecessary obligation, but it is very helpful. Sometimes, when we arrive hungry at the first restaurant we spotted, we are more likely to order something big and greasy because we think thats the only thing that can make us full. Trick your stomach by checking the menu before you arrive. Plan something light and tasty, and once again do not worry- you will not be hungry.
