Obesity Medicine Perspective - Ketogenic Concepts
Keto is short for "Ketogenic"
When you burn fat as your primary energy source, you generate molecules called ketones. Ketones are detectable in your urine, blood and breath.
When you cut your carbohydrate cart, below a certain figure, for most people 20-30 grams, you will have to burn fat as your primary energy source and you will generate ketones. There are many methods to achieve this. No one person owns the keto diet.
Insulin pulls your body out of Ketosis
Insulin will keep you from generating these ketones. To avoid this, don't eat sugar and refined grains in all of it's forms, including breads, crackers and noodles. This includes whole wheat. When you eat these things, your blood sugar goes up, your body creates insulin to control that and you will no longer be in ketosis.
The third class of food is startches, like rice and potatoes. Starches break down quickly in your gut and rapidly raises your blood sugar and then you get an insulin surge. This once again pulls you out of ketosis.
