From EIRO Pharmacist:

So, how does EiroLean™ work and why am I not hungry when I use the EiroLean meal replacement shake? To answer this question, we need to discuss the Eiro RS™ Technology. Why do most “diets” fail? Because you are hungry! The genetic predisposition to eat is always greater than our will power not to eat unless certain metabolic conditions are met. Only when the brain thinks we are full will the cascade of hormonal events be in place for us to not be hungry and preferentially burn fat as fuel. This is the whole concept behind Eiro’s RS Technology.

By combining 4 different types of resistant starch along with soluble and insoluble fiber, EiroLean can restrict calories and still provide satiety (the absence of hunger). Resistant starch cannot be digested in the stomach or small intestine. It can only be digested in the large intestine by the normal gut flora. These beneficial bacteria of the large intestine break down resistant starch into short chain fatty acids (SCFA). One particular SCFA called butyrate might block the body’s ability to burn carbohydrates. According to Janine Higgins, PhD, nutrition research director for the Univ. of Colorado’s Clinical Research Center, “Carbohydrates are the body’s preferred source of fuel. Butyrate can prevent the liver from using carbs as fuel and, instead, stored body fat and recently consumed fat are burned.”(1) A study by Higgins et al showed that replacing 5.4% of the carbohydrate content of a meal with resistant starch increased fat oxidation by 23%. This study showed that this increase is apparently sustained throughout the day, even if only one meal contains resistant starch, and the increased fat oxidation is maintained if one consumes resistant starch on a daily basis.

It appears from this study that resistant starch changes the order in which the body burns food. Usually carbohydrates are burned first, but when resistant starch is present, dietary fat is burned first, before it has a chance to be stored as body fat.(2) If you couple Dr. Higgins study with the pilot study just completed by Eiro Research then the evidence is compelling that resistant starch has a dramatic impact on weight management, especially when incorporated into a support program like EiroFit. Numerous studies have demonstrated that resistant starches from high amylose corn (like the Hi-Maize® found in EiroLean) promotes intestinal/colonic health through its fermentation and action as a prebiotic fiber. It encourages the growth of health-promoting bacteria, reduces pH, and increases the production of butyrate.

We have discussed how butyrate contributes to weight management but it also is important for colon health.(3) EiroLean allows us the health benefits of resistant starches while restricting calories, without feeling hungry: a win-win situation, and with proven results, a home-run in the weight management industry.
