When I'm feeling a little peckish, but not entirely hungry, I always stop by the closest smoothie and protein joint. Jamba Juice has some low-calorie Smoothies, which are made with fresh fruit and 100 percent fruit juice. While they still contain sugar, it's the healthy, natural variety that deserves a place in your diet. Orange Carrot Karma and Berry UpBeet (16 ounces): are probably the lowest in Calories, but it has 38 grams of fruit sugar. Sometimes I get the child's smoothie to cut even more calories, and then I add whey protein and collagen boost for beautiful skin! The only reason why I'm giving it less than perfect score is that this location sometimes close early in the evening. Either the Yelp hours listed is wrong, or they just close it early when there's no longer foot traffic.
