Realtone Keto Reviews: This process uses ketones to fuel the body in the absence of food. A keto diet plan is designed to push you into ketosis by shifting your macro balance towards high fat, moderate protein and very low carbohydrate. This provides an abundance of fat you can use for energy instead of carbohydrates which are used in a traditional diet. The last point I'll make on the starving patient is that, as you can see in the figure below, the glucose level normalizes at about mg/dL within days of fasting, despite no sources of exogenous glucose. Because with so much fat being converted into B-OHB and acetoacetic acid by the liver, a significant amount of glycerol (the 3-carbon backbone of triglycerides) is liberated and converted by the liver into glycogen.
