I face the same challenges. A lifetime of eating habits is hard to overcome.

When it comes to giving up "bad stuff", I try to take a moment and ask, "Do I really, really want this? Or is there a better choice?"

But when I'm hurried or stressed, it's just too easy to fall into an old pattern.

Even small changes add up over time. I've made a lot of dietary changes -- more vegetables/salads, less meat, way less sugar, less alcohol, etc. But it has taken years. And sometimes, I just gotta have the ice cream! It's a slippery slope.

What sort of changes are you looking to make?

First thing we did was to stop stocking the things we knew we shouldn't have in our home. Sure, we make treats for special dinners and holidays, but there are no brownies, cookies or ice cream at hand. Snacks are healthy nuts, high-fiber, low-sugar protein bars (after much testing we found a few tasty ones) carrots, clementines, small apples. If we want chips for a meal, we buy a small bag to share.
Next, we started reading labels at the grocery srote, and stopped buying 99% of prepared meals. It's quick and easy to season & pan grill a fish fillet, chicken breast or lean pork chop and pair it with a fresh or frozen vegetable - we have a long list of 20-30 minute meals.
We also try to share a meal when we go out - portions served in restaurants are enough for 2-3 people! Also, it feels like a real treat to have something different, but we still aren't destroying all our efforts to eat healthy.
