How to get enough fibre on the keto diet

Fibre and the Keto diet for Parkinson's

The ketogenic or keto diet is a very high-fat, very low-carbohydrate, moderate protein diet which has been shown to improve certain symptoms of Parkinson’s in several small studies1,2,3. If not well-formulated the keto diet can lack fibre. Not consuming enough fibre can lead to or exacerbate constipation. Since constipation is a common non-motor symptom of Parkinson’s that can affect quality of life and impact the effectiveness of levodopa, it is super important to ensure you are consuming an adequate amount each day.

Just like all dietary regimes, there is no one-size fits all approach with the keto diet. The amount of carbohydrate required to reach ketosis on a keto diet will vary from person to person. In addition, it is unclear what the ideal ratio of fat to carbohydrate would be most appropriate for people with Parkinson’s. Therefore, the following information should be used as a guide only. For personalised one-on-one advice you should consult a Dietitian. Please note all figures quoted are estimates only.
