This strategy may be the most challenging to consistently employ but can make the biggest dent in your budget. Sit down once a week and plan all the meals for that week, and then shop only for the items you need to prepare those meals. Allow for leftovers in your meal plan, and be realistic about how many nights you might eat out or be too busy to cook. Not only does this strategy cut down on the amount of food you buy at the grocery store, but it also decreases the amount of food you waste.
