For people who are very ill, reducing carb intake and “weaning” into the diet may be the appropriate path. Some people can jump right in. If you’re very sick I recommend weaning carbs for a few months leading into the diet.
Month 1: No grains or dairy, drink only water. That’s going to be much lower in inflammatory foods right away. Sparkling water is fine.
Month 2: Remove soy, legumes, and eat only meat and vegetables and some fruit. Eat meat first at each meal so you end up eating mostly meat.
Month 3: (If your symptoms haven’t been alleviated by the Month 1 or Month 2 diet, continue to the Lion Diet)
