Another typical fad diet?
Actually it’s been around for a while now, and people are getting some pretty good results from it. So what exactly is so different?
Well most of these fad diets you find simply tells you to eat this certain type of food and avoid those certain type of food and viola, you’re on your way to losing a hundred pounds. Of course, a lot of them don’t really work and makes very little sense.
What is special about the Keto diet, short for ketogenic, is that it changes how your body feels. And most importantly, how your body uses energy by placing you into a state known as ketosis. And this Is where all the magic happens. In ketosis, your body starts utilizing substances known as ketone bodies, which are produced by the breakdown of your body fat triglycerides.
Quick science, first understand that your body loves glucose. If it has glucose on hand, it’s going to use that first for energy. Ina keto diet, the amount of carbohydrates you consume goes down, therefore, the amount of glucose goes down, too. In order to combat this, your body uses stored glucose in the form of glycogen, but then that’s going to run out as well.
The next step is to convert a substance known as oxaloacetate in the liver into glucose. At the same time this is happening, your body is breaking down your fat into free fatty acids and sending it to your liver to metabolize another important substance known as acetyl.
Acetyl CoA is then placed into the Krebs cycle in the liver cells to produce energy. But it can’t do that right now. Remember that oxaloacetate that was being broken down into glucose?
Well, oxaloacetate is also needed for the Krebs cycle to function. Now your liver has all of these acetyl CoA lying around so it decides to break it down into two substances called acetoacetate and beta-hydroxybutyrate, which are known as keton bodies.
It sends them into the bloodstream where other body cells pick them up, convert the ketone bodies back into acetyl-CoA. Into Krebs cycle and energy is produced! This is also really good news for your brain, since even though your brain loves glucose too, it can function on ketone bodies as well.
In fact, ketone bodies provide more energy per gram for the brain versus glucose, so win-win for your mental capacity! Not so dark, everything sounds good. Your body no longer relies heavily on carbohydrates; it burns a lot of fat, and your brain functions pretty well.
But of course, there is always a catch, a number of catches in this case. Studies show that power output decreases in cases where maximum intensity is required. This makes sense because the breakdown of glucose vie glycolysis, plays a crucial role in providing immediate energy for your body.
