You must first cut back on your carb intake in order to go into ketosis. This entails avoiding starchy foods including grains, potatoes, rice, bread, and pasta. To keep track of what you consume, you might find it beneficial to keep a food journal.
Your body starts creating ketones once you start consuming fewer carbohydrates. When there is not enough insulin in your blood, ketones are formed. Your body can absorb nutrients from food thanks to the hormone insulin. Your body begins to use fat reserves as energy if you don't make enough insulin. Your body will remain in ketosis as long as you keep consuming less than 50 grammes of net carbohydrates each day.
