Ketosis is when you have very low carb consumption and your body converts fat into ketones by your brain to use as energy, fat can't cross the blood brain barrier to be used as energy for the brain. Fat adapted means that you are able to burn fat as energy. You are only able to do this if you have lower levels of insulin in your body because insulin prevents your body from breaking down fat. Generally you need to consume less than 50 grams of carbohydrates per day to get into ketosis.
If you are in ketosis, it means that you are fat adapted because you are able to use fat as energy and you can use it to produce ketones. You can be fat adapted and able to burn fat deposits when fasting to fuel yourself without being in ketosis because you consume to many carbs from vegetables to enter ketosis.
