When you are trying to lose weight, focus on the positives about food, not the negatives. Don't think about cutting out the "bad" foods; think about all of the good things on the healthier foods you'll be eating. This will make you feel better about the food choices you're making, instead of regretting the loss of the junk foods.
Eat more nuts when you are trying to lose weight. Nuts are a great snack food and can be used in place of meat in salads and stir-fries. There are a wide variety of nuts, so that you won't get bored of eating them. You can even soak nuts in water before you eat them for a different texture.
