Be careful with long term keto. I've worked with many clients who come to be with thyroid issues after being on a ketosis diet. Ketosis should not be used as an ongoing diet. Make sure you work in carb re-feed meals on a regular basis and track your morning temperature every day. This will provide an insight into your thyroid health. If your temps start dropping you need to get off ketosis for a while.
