RightSize smoothies are the first meal replacement smoothies on the market to offer single-serve convenience, Chapman adds. They are available in an eight-portion variety pack which includes two of each flavor: Lean Cocoa Bean®, SkinniVanilli® Slend-A-Berry® and Leano Cappuccino®. The single serve packs can be purchased online at myrightsize.com. RightSize meal replacement smoothies are made with a combination of nutrients to curb hunger and help with weight loss, including 15 grams of protein (when made with skim milk), 6 grams of fiber, over 20 essential vitamins and minerals, as well as natural ingredients such as green tea and ginger root extracts. RightSize smoothies have no added caffeine and are gluten-free. "Many diets fail because people get hungry all the time," explains Chapman. "The combination of protein and fiber in RightSize smoothies satisfies that hunger to help dieters stick to their plan and lose weight. "Best of all, RightSize smoothies taste like delicious, creamy shakes, which is a huge benefit. People look forward to their next smoothie, which can make it easier for them to stay on their diet," she adds.
