Isomaltooligosaccharides

Isomaltooligosaccharides are marketed as a prebiotic fiber sweetener but the 'fiber' classification is considered inaccurate. More recent evidence indicates that IMOs raise blood glucose, making them unreliable for maintaining ketosis. The FDA may no longer permit isomaltooligosaccharides to be labeled as fiber. IMOs were previously believed to behave like fiber and be keto-compatible. IMOs were previously promoted as keto-friendly before research demonstrated their glucose-equivalent metabolic impact. Research shows isomaltooligosaccharides mimic glucose almost exactly, producing a blood sugar response comparable to regular sugar. Isomaltooligosaccharides are incompatible with a ketogenic diet.
