If this is your first approach at a Paleo or Primal diet after years of living on the SAD (Sandard American Diet) it is likely you will have detox symptoms. This isn't so different than that of a drug addict but less severe. You will have insatiable cravings for foods, you may have flu like symptoms, and you may just have lethargy and general fatigue. This may be referred to as a Herxheimer reaction. This is typically relegated to those taking antibacterials and resembles bacterial sepsis but I use the term for detoxing, while maybe not clinically correct in its usage it does apply here.
Detox reactions are occurring due to the fact that you're eliminating the diet of bacteria in your gastrointestinal tract. The die-off of critters in your gut happens at such a rate that the liver cannot handle the load and the result is a feeling of malaise. There's really little that one can do during this period which, depending on your state of health, may be a couple days or even weeks. Don't let this discourage you from taking on the change in diet though. You may go in feeling awful but on the other side it is worth the trouble and the elimination of the bad bacteria floating around the body. A lot of Paleo websites fail to mention this portion of things since there may be trepidation of those looking to change their diet and lifestyle. All I can say is to stay the course with it.
Things that can help during Detox:
- Epson Salt baths
- Magnesium Supplements
- Ascorbic Acid (Vitamin C)
- L-Glutamine (which helps rebuild the gut lining)
- Plenty of fluids to help flush
- Milk Thistle to aid the liver
- Relaxation and Patience
