On second thought… No
🌟 Can everyone become fat adapted?!

Question again…what’s the difference between being in ketosis and being fat adapted? As I understand this, my carb inout has been super low, and I’m trying to raise fats and reduce protein so I should go into ketosis but fat adapted? Thanks!

When you’re fat adapted you’re able to burn body fat for your body’s energy. Ketosis is a metabolic state when a person has ketone bodies in their system. This is a result of burning fat for fuel.

Ketone bodies are chemicals with certain characteristics that the liver makes by partially metabolizing fatty acids. There are three that the body produces: acetone, acetoacetate, and β-hydroxybutyrate. (Strictly speakingm that last one isn’t actually a ketone, but it counts as a “ketone body,” lol.)
The liver makes ketones only when carbohydrate intake is low. Once you start a ketogenic diet, you quickly enter ketosis, a state defined by a certain level of ketone bodies in the blood, once your supply of glucose is used up. But fat-adaptation is a switch in the muscle tissue, from metabolizing glucose to metabolizing fatty acids, and there are cell-level adjustments that need to be made. These adjustments take time, so it takes generally about six to eight weeks for people to become fully adapted to metabolize fat. At that point your muscles will actually refuse to metabolize glucose or ketone bodies, sparing them for other cells in the body that need them.
The brain, by the way often does even better using β-hydroxybutyrate than it does using glucose. I believe it switches readily between them, unlike the muscle cells.
