Most people have no idea how to eat. They think healthy just means expensive organic/health foods and stuff. In reality you can lose weight by simply eating less of the same, even if your diet is crap. And if you want to eat healthily for cheap, you can eat for a few days on bulk rice, beans, whichever lean meats and veggies are on sale, and a few other things for the price of one obeast's lunch haul at McDonald's.
