Did you make a New Year's resolution to eat more fruits and veggies and less processed foods? You know habits are difficult to stick with but one technique that can work is that of a 'fresh start.'
Fresh starts are often associated with moving to a new home or starting a new job. I also think that decluttering a space can help you see it (and associated habits) in a different way.
So, today, clear undesirable food from your refrigerator – disliked, wilted, spoiled/spoiling. If you have the time, wipe down the shelves.
Create a go-to space for leftovers so everyone in your home knows what needs to be eaten. Try to develop the habit of doing a quick cleaning before you go grocery shopping (or on trash day).
Put foods that you want you and your family to eat in the most obvious spot. (So, the vegetable bin might not be the best place to keep cut up veggies meant for snacking.)
And, if there are foods that you keep for your spouse, kids, or grandkids … but that you want to avoid … put those foods in aluminum foil, opaque food storage containers, or on a low shelf behind other things.
Make it easy to stick to good habits and more difficult to engage in bad habits.
