What Is Insulin? Understanding The Role of Insulin in Metabolism and Healthy Aging

Insulin is a hormone produced by beta cells in the pancreas with a central role in the regulation of metabolism and cell energy reserves. The major metabolic action of insulin is to regulate blood glucose levels and to promote the storage of energy substrates as macromolecules that can be mobilized between meals or in contexts of high energy demand.

The Role of the Gut-Brain Axis in Metabolism and Energy Homeostasis

The Role of the Gut-Brain Axis in Metabolism and Energy Homeostasis

In this article, we will take a look at the role of the gut microbiota and the gut-brain axis in metabolism and energy homeostasis. We will learn how food-derived chemical signals—nutrients and microbial metabolites—are translated in the gut into endocrine and neural signals that convey information about the caloric load and composition of a meal to the brain.
