I am thinking about buying some of these to mix in with the meals and soups in a bid to trick my stomach into feeling like Ive eaten something. Ive read a report that one you get passed the rubber texture theyre actually quite good for filling you up, they have 8 calories per 200grms and no fat or Carbs. Has anyone used these? what were they like? Did they improve the consistency of the meals? Did it alter your weight loss in any way??
