When you consume carbohydrates, your body breaks them down into glucose, which is then used for fuel. By restricting the amount of carbohydrates consumed, the liver begins to produce ketones. This process shifts the body toward utilizing excess stored fat for energy in place of the missing carbohydrates.
Those following a keto diet to reach their goals are encouraged to follow a meal plan filled with fresh vegetables and nuts while food items that contain refined carbohydrates such as bagels, pasta and cereals should be avoided.
Always consult your doctor before radically changing your diet – you never know if you will encounter any problems beforehand.
