Summary
A Reddit user with bloating for about 18 months and joint, muscle and nerve pain from August 2022, whose energy was normal until a ketogenic diet in May 2025. Fatigue began with keto and extreme tiredness after meals followed, especially during the less carnivore phase; keto included a month of strict carnivore. On an animal-based diet since October 2025 they sleep 10-11 hours, have low energy and brain fog, and joint and muscle pain is mostly gone; blood tests were normal apart from high cholesterol.
