What is Eat Water Slim Pasta made of? So, let’s get things straight… this low-calorie pasta is carbohydrate free, wheat free, fat free and still tastes just like pasta? But how? What is it made of? The secret is in Glucomannan – a plant-based, water-soluble fibre in Konjac flour. When ingested, Glucomannan like most soluble fibres creates a sensation of fullness that can reduce appetite and delays stomach emptying, keeping you feeling fuller, leaving you less likely to snack or binge eat. This zero-carb pasta both satisfies pasta cravings and fills you up – a great weight management duo!
