[41] [42] The inability of the β-cells to produce sufficient insulin in a condition of hyperglycemia is what characterizes the transition from insulin resistance to type 2 diabetes. Insulin resistance is strongly associated with intestinal-derived apoB-48 production rate in insulin-resistant subjects and type 2 diabetics. [43]
Increased insulin secretion leads to hyperinsulinemia, but blood glucose levels remain within their normal range due to the decreased efficacy of insulin signaling. [4] However, the beta cells can become overworked and exhausted from being overstimulated, leading to a 50% reduction in function along with a 40% decrease in beta-cell volume. [ 9 ]
Type 1 diabetes is caused by the destruction of β-cells—the only cells in the body that produce insulin—and the consequent progressive insulin deficiency. Without insulin, the body cannot respond effectively to increases in blood sugar. Due to this, people with diabetes have persistent hyperglycemia. [31]
Type 2 diabetes is due to insufficient insulin production from beta cells in the setting of insulin resistance. [13] Insulin resistance, which is the inability of cells to respond adequately to normal levels of insulin, occurs primarily within the muscles, liver, and fat tissue. [60] In the liver, insulin normally suppresses glucose release.
Insulin is produced by the pancreas in a region called islets of Langerhans. In the islets of Langerhans, there are beta-cells, which are responsible for production and storage of insulin. Insulin is secreted as a response mechanism for counteracting the increasing excess amounts of glucose in the blood.
Beta cells are specialized cells in the pancreas that produce and release ... test results showed that after 12 weeks, the low-carb diet improved insulin’s effect on blood glucose levels by 32% ...

Insulin is a peptide hormone containing two chains cross-linked by disulfide bridges. Insulin (/ ˈ ɪ n. sj ʊ. l ɪ n /, [5] [6] from Latin insula, 'island') is a peptide hormone produced by beta cells of the pancreatic islets encoded in humans by the insulin (INS) gene. It is the main anabolic hormone of the body. [7]
