Insulin is a hormone that lets cells throughout the human body, predominantly in the liver and in the muscles, to absorb glucose and utilize it to generate energy. Insulin resistance interferes with that absorption, and it can lead to the development of prediabetes or type 2 diabetes. Insulin resistance has a strong genetic factor. Diabetes is a metabolic syndrome in which the body has high sugar levels for prolonged periods.
Insulin resistance is a pathological disorder in which cells fail to respond to the hormone insulin. The body processes insulin when glucose starts to be released into the bloodstream, primarily from the breakdown of carbohydrates within the diet. Insulin resistance makes it difficult for the body to utilize fat for energy. Limiting carbs can be helpful.
