Diet is a crucial factor as well, if you want a simple way to eat well, buy a crockpot. Fill it with beans and vegetables, and lean meats (elk, bison, etc) because if you use ground beef, you quickly reaize why it is not healthy, there is a layer of grease sitting on top, and you can't ladle it out, and you can't brown the beef and drain it, either. It is visual proof that you think you might be avoiding this by draining it from your frying pan, but you're not.
Elk and bison don't leave this grease. You make a bunch of this and have bowls ready to freeze it, and then put a bowl in the fridge before bed and have a meal ready tomorrow.
