Hello Guys,
During prolonged fasting and starvation, your brain is able to gradually change from eating only glucose and begin using another energy source called ketone bodies. Your liver makes ketone bodies out of fatty acids. This change in your brain from using glucose to using ketone bodies for energy is gradual over many days. By the time you have fasted for a week, your brain can get about 7 out of 10 calories that it needs from ketone bodies, but still needs about 3 out of 10 calories from glucose. After 2 to 4 weeks, your brain has fully adapted to starvation and gets about 9 out of 10 of its calories from ketone bodies. Example of Advertisement includes various creative visual elements which attract consumers with more effectiveness than a newspaper advertising. But because your brain still requires about 1 out of 10 of its calories from glucose, your body will still break down and eat some of your muscles to feed your brain.
Thanks
