RE: KETODIETING FOR WEIGHT LOSS IS SOLELY BASED ON KETOSIS.
I think I have a question. If we were sort of become depleted of glucose, why the body choose to use fat instead of degrading muscle? I mean, when we run out of energy, the body metabolism would be slowed down and most of the physiological changes indicate that the body trying to conserve energy instead of using them. So why does it choose to use fat storage when it can degrade muscle in a process called gluconeogenesis since muscle is an expensive tissue (requiring a lot of energy to run)?
If we are deplted in glucose the body would use muscle proteins but nit for long because the proteins are also needed for other processes so it shifts to fat storage.
But in a keto diet which is rich in fat the glycolysis and gluconeogensis would be reduced because fat is abundant and it has to be utilized.
What the post is simply saying is that ketodiet lets your system run solely on ketosis doesnt mean that glycolysis and gluconeogenesis would not occur
@conficker, @giftessiet. The body does not degrade “muscle” or “muscle proteins (e.g actin & myosin)” in peroids of starvation. They degrade glycogen rapidly and as starvation is prolonged, the glycogen stores get depleted and the body has to utilize fats as an alternative. Proteins are rarely being used unless in very extreme cases. Ketogenesis is necessary cause it makes available ketone bodies which can be utilized by the brain and others
extra-hepatic tissues. The liver cannot even utilize these ketone bodies despite being the main producer of these bodies and this is because the liver cannot undergo ketolysis which is necessary for the utilization of ketone bodies.
