This video should be seen by every person who is insulin resistant, diabetic, hypoglycemic etc. I wish doctors or the medical support teams would use this to educate people on how our bodies work internally.

Correction... The brain uses 120 grams of glucose a day if It readily available . However, if it isn’t, the liver makes enough to use. Additionally, the oxidative priority of using glucose is first, but the brain doesn’t use it as efficiently as the secondary fuel. The secondary fuel, if glucose can be reduced, is ketones. Ketones also form ATP. They supply energy throughout the whole body. You can stay in ketosis during feeding states. Carbohydrates reduction will keep you in a healthy state of ketosis. Ketones can be produced when well fed.

Very fascinating that fatty acid is used for the brain and heart ! Learned something new as always from you guys, awesome! Keep on the hard work, you guys rock!
@vidakmilacic 8 years ago

Statement 'Ketone bodies are only used by heart / brain' is FALSE. Ketone bodies are used inside muscle cells, specific in mitochondria to produce ATP. Gluconeogenesis is not driven by fatty acid or amino acids. It is driven by fatty acid and amino acids together. There is another kanacademy video which explains this much better.
