I've been eating lots of oatmeal and shakes since I got a tongue piercing. I don't need to any more, it's just a wicked diet with no-cal sweetener in everything.
Oatmeal is magic. It's versatile like rice but waaaay faster. Flavor it with anything, sweet or savory: Fruit, pb&j, maple syrup, apple sauce, cocoa powder, eggs and avocado, eggs cheddar and bacon bits, apple and bacon, onions peppers and sausage, mushrooms and caramelized onions, full English breakfast with oatmeal instead of beans, chicken stock and scallions and nori and pepper paste. So gooood.
Shakes are way lower calorie when you don't use icecream. Start off with 50/50 milk and plain greek yogurt, then add fake surgar, flavor (fruit juice concentrate, protein powder, fruit/herb extracts), and other thickeners (whole fruit, pudding mix, xanthan gum). Fruit, choco, vanilla, peanutbutter, choco with fruit, vanilla with fruit, peanutbutter with fruit, pb with choco, mint extract with fruit or choco or vanilla.
Best part is I can make the food at work. No need to use precious off-time at home for food prep. Hot water for oatmeal, blender for shakes.
