The Bariatric Advantage High Protein Meal Replacement comes in a single serving packet or an economic 24-serving tub with a measured scoop to make accurate dispensing easy. Each 140 to 160 calorie serving provides a full 27 grams of protein, with only 7 grams of carbohydrate (of which 5 grams are fiber, and only 1 gram is sugar) and a half gram to 4 grams of fat. They are also lactose-free to best meet the needs of weight loss surgery patients. One hundred percent of the protein is from a high quality whey protein isolate (There is no soy protein, only a small amount of soy lecithin to mask aftertaste). Fortified with between 15 and 50 percent of the DV for 23 essential vitamins and minerals, this product makes a perfect pre-operative weight loss shake or post-operative meal replacement for bariatric surgery patients. Our meal replacement also comes in a great variety of flavors (chocolate, vanilla, strawberry, banana) as well and an unflavored shake that can be mixed with soup, yogurt, fruit or home-purchased flavorings.
