For fat to be metabolized properly, carbohydrates must be present. The basic message is simple when it comes to selecting the amount and type of carbohydrate foods. Carbohydrates should make up 45% - 65% of the total daily calories in a healthy diet. At least 130 grams of carbohydrate should be included in the diet to prevent ketosis. Whenever possible, replace highly processed/refined grains, cereals, and sugars with minimally processed whole-grain products.
[...hence why i cringe at low carb 'diets' or 'diets' that eliminate carbs]
