You know that a lot of what we eat isn’t the best choice, but you end up choosing it anyway. I think this is mostly out of habit. Decades of living at your parents’ house have ingrained in you a habit of buying and eating the wrong kind of food.  It’s going to take a conscious effort, but now is the best time to make the right choices. You need to harness the power of habit and genuinely enjoy healthier food so it becomes part of your new day-to-day.
