We have discussed the benefits of resistant starch, but there are 2 other ingredients of EiroLean that are just as important, and make the resistant starch more effective; Fiber and Protein.  Fiber has 2 types, insoluble and soluble.  The most important type in regards to weight loss is the soluble type.  Here’s why.  Fiber is bulky, so it tends to make us feel full.  Insoluble fiber moves out of the stomach fast, unless there is fat, protein, or…soluble fiber to slow it down.  Soluble fiber, like the ground oat bran found in EiroLean, slows down stomach emptying which keeps us feeling full longer.  Because the contents of the stomach enter the small intestine more gradually, satiety is maintained longer.  In the small intestine soluble fiber also slows things down, which helps to maintain feeling full.  By the time this satiety effect is wearing off, the resistant starch is now entering the large intestine, where the process of digestion by the gut flora creates the SCFAs (discussed in the previous post) that help us burn fat, and thus add to our satiety.  So how does protein factor into this?  As a macronutrient, protein, especially high quality protein like the Whey Isolate found in EiroLean, helps curb your appetite by releasing a hormone called PYY.  This hormone works by slowing the gastric emptying and directly suppressing appetite.(1)  Now we have 2 mechanism slowing down the stomach emptying and keeping us feeling full longer untill the resistant starch can do its thing in the large intestine.  All 3 of these mechanisms:  resistant starch, soluble fiber, and quality protein, allows us to consume a 230 calorie shake and make the brain think we just had a 500 calorie meal.  When you can restrict calories this way, weight loss is more manageable and success is more probable.
