Understanding Ketogenesis: Anabolism and CatabolismIs gluconeogenesis catabolic or anabolic? Anabolic, it requires energy. What does gluconeogenesis generate? How many reactions in gluconeogenesis are the reverse of glycolysis? Gluconeogenesis anabolic or catabolic are the 3 enzymes found in glycolysis but gluconeogenesie gluconeogenesis?

Ketogenesis is a pretty complicated process and can create a lot of confusion. I know a lot of people on Keto diets that would say too much protein could turn into carbs hint: I see a lot of others say you can build muscle easier on a ketogenic diet, with the same or less dietary protein hint: The key to understanding ketogenesis and why the aforementioned statements are true lies in understanding catabolic and anabolic reactions.
Catabolism, in brief, is the breakdown of large molecules into smaller ones. Anabolism is the opposite; creating larger things from smaller ones, such as gluconeogenesis or building muscle. For example, insulin will promote catabolism of carbohydrates.
Overall, however, insulin is anabolic because the overall state of the body switches to storage mode. Even though insulin can increase the rate of glucose metabolism, increased glycolysis directly contributes to lipogenesis and the storage of fatty acids. Similarly, glucagon stimulates catabolism i. Anabolic reactions like GNG in a catabolic state and catabolic reactions like glycolysis in an anabolic state are important for proper homeostasis.
Glycolysis after feeding and the presence of insulin anabolic prevents possible hyperglycemia in the context of high consumption of carbs. GNG during times of fasting catabolic prevents hypoglycemia. There is a strict level of homeostasis that the body must maintain for survival. Understanding these reactions and their physiological conditions are important to understanding how and why ketogenesis works and its importance. Similarly, the lower insulin response from protein relative to carbohydrates and the simultaneous glucagon release make muscle protein synthesis a little bit harder to manage in a low-carb diet.
Additionally, insulin is present for longer periods of time following a meal containing high ish amounts of carbs, meaning the anabolic state and muscle protein synthesis lasts longer on a high-carb diet than on a low-carb diet. Additionally, the insulin response created by protein ingestion will probably inhibit lipolysis and the production of ketones for a short time, but will return back to fasting levels relatively quick.
This is why protein restriction during weight loss on a low-carb diet is not necessary, and may actually be harmful. You should consume a little extra protein to compensate for the loss of protein created during the catabolic state created during low-carb diets.
Even excess protein in medical conditions may not be so bad, IMO. Sign in Get started. Anabolism and Catabolism Ketogenesis is a pretty complicated process and can create a lot of confusion. Never miss a story from Stephen Decker , when you sign up for Medium.
