  1. Candida die off yes !and remember the changeover means worms and other parasites are dying off too .they will fight you to eat the carbs by pumping you full of chemicals to make you crave what THEY need to eat to survive. Look it up it’s really a big part of withdrawing symptoms and the reason many fall back to feeding worms for the resulting comfort. Also bread and cheese combo is food for addiction as it feeds opioid receptors in the brain. Xx

  2. I find it curious that no one talking about the Keto Flu mentions the inevitable die of of Candida for most people when transitioning to Keto. Candida die off is brutal, yet no one mentions it. To me, it feels like the elephant in the room. Keto from Paleo was easy and I never experienced the ‘flu’, but SAD to Paleo was vicious. IMO, more because of the shift in gut biome than electrolytes. I’m certain electrolytes would likely have helped me had I known what I do now, but there is still a die off that makes people feel crummy.

  3. When I started Paleo 7 years ago, I felt that way…headaches and exhaustion but it improved as I learned how to eat more healthy foods. Elana’s cookbooks helped so much. I started feeling full and having more energy!

  4. Is there a Paleo flu? I am having a hard time trying to ditch the carbs, I feel tired, irritable and foggy headed.

    • Sheila, that is such a fantastic and interesting question. I imagine one could become a bit sluggish in reducing carbs and going through withdrawal. I hope you’ll keep me posted on how you’re doing :-)
