1. People like to do things that are easy and don’t like to do things that are hard.
Use this to your advantage by having the healthier foods cut up and available for grab & go snacking. The not-so-healthy foods need to live in more inconvenient places like high shelves or the deep, dark cabinet corners. If you have to get on your hands and knees to dig back into a cupboard for the cookies, you’ll find they become much less appealing.
2. If you want to train a dog, you’ve got to be smarter than the dog. Works with kids too.
If all else fails, you have one undeniable option – your checkbook. Chances are, you or your spouse buy nearly 100% of the food your family eats. Set firm policies for what does and does not come into your house. My husband can buy ice cream, bacon, and big bags of shredded cheese. He’s over 21 and he can do what he wants, but he can’t do it out of our regular grocery budget. If he wants those things, we’ve agreed that he must pay for them with cash out of his pocket. He still gets them sometimes, but we don’t have them nearly as often as we used to.
