Insulin is a hormone produced by the pancreas to regulate blood sugar levels. When we eat carbohydrates we disturb homeostasis by dramatically raising our blood glucose levels. High amounts of insulin are released by the pancreas to combat this. Insulin directs excess glucose to be converted into fatty acids and transported to fat cells to be stored as triglycerides(fat). When insulin levels are high, it supresses ketones and the release of fatty acids from fat cells as well. This dramatically reduces the capability of the body to use ketones/stored fat as energy.

Insulin production is also directly affected by dietary sugar. When you eat dietary sugar you will have high glucose and high insulin levels while if you don’t eat dietary sugar you will have low glucose and low insulin. While you have low insulin and glucose this is when your body is able to make much more effective use of ketones/stored fat as energy.
