Gelesis, a Boston-based company working on treatment for obesity, has created a superabsorbant hydrogel derived from food components that it is marketing under the name, "Attiva." These Gelesis Attiva Capsules will revolutionize the lives of those suffering from obesity.

Fifteen years of food-based polymer research went into making the appetite-suppressing substance. The user swallows an Attiva capsule and one or two glasses of water before a meal. The substance then swells hundreds of times its original size to create a full feeling and reducing the rate at which food is absorbed into the bloodstream. A side benefit is improved glycemic control.
