ORALLY ADMINISTERED SUPPLEMENTS AND METHODS OF REDUCING ABSORPTION OF CALORIES AND MODIFYING THE NUTRITIONAL VALUES OF CONSUMED NUTRIENTS
Methods and orally administered supplements are provided, which use bacterial strains to reduce absorption of calories by a subject from consumed nutrients. The bacterial strain(s) are selected to metabolize at least part of the nutrient(s) consumed by the subject, and may be selected to be excreted and/or to have metabolic products that are excreted by the subject - making some of the consumed calories unavailable to the subject and/or reducing any of a glycemic, a cholesterol/lipids level and a protein value of the consumed nutrient(s). Appropriate coatings or covers may be applied to protect the bacteria from gastric acids, and the specific strains may be adjusted to increase their nutrient metabolism, improve their resistance to intestinal chemical conditions and optimize bacterial communities that may have synergic effects in nutrient metabolism, in a way that makes some of the calories unavailable to the subject.
