Should I worry about fiber?

It’s common to reduce fiber intake when switching to a ketogenic diet, simply because fiber is most abundant in foods that are high in carbohydrates, particularly vegetables and grains. Fiber is an important nutrient that’s essential for good health, and although it is technically a carbohydrate, it does not increase blood glucose or insulin levels. So we highly recommend making an effort to get enough fiber unless you are on a carnivore or low fiber diet, in which the approach is slightly different.
