I have at leat 10lbs of frozen 1lb bags of mix veggies(broc, Cauf) in my freezer at all times, Wal Mart .98 per lb and eat about a 1.5 bags a day, yams, berries(frozen Sam's Club), easy to get carbs, but you do have to EAT them and prepare them enough diff ways not to get bored.
Few pieces of fruit a day, problem solved, if not much fruit and you do not want to add a tad of Oatmeal, then bottom line, eat more veggies, day in, day out. More color the better.
PS. Sauerkraut at around 1.28 for two lb bag is a bargain and it's a fermented food, double bargin.
