Hmmm...
Sensa is commonly referred to as The Sprinkle Diet, although the Sensa weight loss regime isn’t really a diet as such, but something you would add to your current diet.
Sensa sprinklings are in fact flavor-enhancing ‘flakes’ made from maltodextrin, tribasic calcium phosphate, silicon dioxide, and flavorings. You simply sprinkle a dash over your food (as you would salt or pepper) and it then amplifies both scent and flavor. Sensa is actually meant to work using your sense of smell, tricking your brain and belly into thinking that you’re full.
Stole this from another site... I'm dubious tbh
