Buy whole wheat bread, whole rye or six grain bread. Avoid high fat muffins, cakes and cookies. Most store bought muffins have high fat content. Pasta, grains, like brown rice and barley, and dried legumes are low in fat and can be high in fibre. Ones that need cooking like rolled oats and mixed grain.
Crackers are often high in fat.
Buy more of the low fat ones like soda crackers, melba toast, rice cakes, water crackers, and bread sticks. Frozen fruits with no added sugar and plain vegetables are good buys. Frozen meals and entrees should be lean or light. Watch out for high fat frozen fare like macaroni and cheese, souffle, quicke, chinese food, chicken and chips, fish and chips, pizza, croissants, puff pastry, ice cream, frozen yogurt. Don't allow a snack attack to cloud your judgement.
