This is what it should be avoid on a ketogenic diet : foods that contain a lot of carbohydrates, both sugary and starchy.
This includes starchy foods such as bread, pasta, rice, and potatoes. These foods are very rich in carbohydrates.
Numbers are grams of net carbs per 100 grams, unless otherwise noted.
Also avoid or limit highly processed foods, and low-fat diet products.
A ketogenic diet should be moderately high in protein and it probably will be higher in fat , since fat provides the energy that you no longer get from carbohydrates. Low-fat products generally provide too many carbohydrates and not enough protein and fat.
