I'm an everyday smoothie girl. I gifted myself a Vitamix several years ago and make a pretty powerful drink every morning, which I enjoy as I've never been a "breakfast" person. My DH has jumped on the bandwagon, too, so he regularly helps with preparation.
Of course, we all seem to "react" very individually on SBD, but my experience with my morning smoothie is fantastic energy and lack of mid morning hunger. I don't think our mixes would always rank "high" as taste, but nutritionally, they are fantastic.
My standard veggies are carrot, cucumber and beet.
I always add apple and fresh ginger root.
I add two powders; one a non/soy protein power and the other a "greens" powder.
When berries are fresh and affordable I love to add them fresh yet this time of year I will buy organic frozen blueberries and cherries at costco to add. Sometimes I add banana.
Sometimes I add flax or chia seeds.
I can't really say that having a morning smoothie is helping my weightloss. What would help my weighloss would be to stop post dinner snacking.
What I can say is I've never felt better and in the spring when we visited my DH's cousin who is a MD, she commented that we were "radiant" and that I looked healthier than I did when she first met me 20 years ago. That was a true compliment since I was at normal weight then.
