Losing weight is a challenge almost as difficult as reading an entire dictionary or climbing a tree that’s covered in canola oil. Take an expert approach to tackling the task of slimming down with today's Groupon: for $59, you get one 24-pack case of RightSize smoothies and one 15-pack of SlimminAde drink mix packets from RightSize (up to a $119 value). Today's Groupon is redeemable online only and includes shipping.

RightSize streamlines the pound-shedding process with an appetizing array of meal-replacement shakes and weight-loss supplements. Available in both SkinniVanilli and Chocolate Mousse Reduce, each of the 24 ready-to-drink smoothies combines sundae flavors with nutritional necessities, packing in plentiful fiber and protein as well as a half day’s requirement of more than 20 vitamins and minerals per serving. Each prepackaged smoothie is conveniently sized for a quick, complete meal on the go, with just the right amount to replenish famished fuel tanks more efficiently than fast-food lunches or glove compartments filled with cookie dough.

RightSize also explores the tastier side of nutritious hydration with its SlimminAde drink-mix packets. Drinkers sprinkle one pouch into 16 ounces of water and shake until dissolved, quenching thirst with a lip-smacking lemonade flavor and a hip-shrinking caloric count. SlimminAde also boosts vital stats, filling individuals with daily allowances of vitamins, boosting omega 3 fatty acids, and increasing the ability to dunk on regulation-size rims.
