"When people cook most of their meals at home, they consume fewer carbohydrates, less sugar, and less fat than those who cook less or not at all—even if they are not trying to lose weight," says Julia A. Wolfson, a CLF-Lerner Fellow at the Johns Hopkins Center for a Livable Future and lead author of the study. Source
-Learn to love what you cook. When the food you make tastes better than than the food you can purchase, you might be more motivated to cook at home more often. It's not hard to learn how and just takes a bit of practice.
-Combine packaged foods with home cooked additions. For instance, you may not have time to make butternut squash ravioli. But you can make a sauce filled with sautéed vegetables and pour it over the packaged ravioli you find in the frozen section of the store so you get at least some fresh ingredients.
-Make food in bulk and make it ahead. This practice becomes easy when you pick a day of the week or weekend to make something you really enjoy and make enough of it to fill a large bin. This could be a mixture such as rice, beans, tofu, and frozen veggies including peas and corn. This mixture can be heated or sautéed and eaten as a rice bowl, put into burritos, and even mixed into salads. When you get good at it, you can cook food in bulk without taking too much time away from your other in house activities.
Lastly and most importantly, have ingredients well stocked in your kitchen. Spend money at the grocery store early in the week so your valuable food allowance goes to buying raw vegetables and fruit that you'll turn into healthy and amazing homemade meals!
