Be careful with smoothies from ice cream or other fast food places -- they are usually full of lackluster ingredients and way heavy on the calories. Always avoid artificial sweeteners if they are using those to make it "light." Blue Diamond Almond/Coconut blend is great - get the sweetened one at first, then take yourself down to unsweetened. You can get it in the refrigerated milk coolers (regular almond milk can also be found on the store shelves at room temperature). Look in the health section.
Check out the new book by Rachel Beller, Eat to Lose, Eat to Win:
http://www.bellernutritionalinstitute.com/. It's refreshingly simple and if you will follow her recipes (basically, BOOST the veggies!) you will notice a difference and feel better. She even includes smoothie recipes, but my own favorite recipe is: almond/coconut milk with oats, soy nut butter, honey and frozen banana. Yummy breakfast to fuel you!
In the produce aisle, you can grab a box of organic "power greens" (salad) and find a smoothie recipe right there on the package. You dump the greens in the blender and add a green apple, lemon juice, and not much else, to make a terrifying looking drink that is super healthy. We eat all of these things...my husband loses 5 lbs. and I don't lose anything. Go figure!
On a side note, Daisymarie and I are in the same location - small world =)
