Do carbs and insulin make you fat? The argument centers on the ability of insulin to promote the conversion of carbohydrate to fat and lock fat in adipose tissue, as well as the necessity of glucose to provide the backbone to fat molecules within adipose tissue. But the argument ignores that all of these pathways are fundamentally regulated at a biochemical level by how much energy you need and how much you have. In episode 44 of Mastering Nutrition, we take a deep dive into the details of the biochemistry and physiology and see how insulin serves as a gauge of whole-body energy and glucose availability but simply can’t be the thing that makes you fat.
