I'm a fan of balanced meal. Not too much fats, protein or carbs. I'm on gluten-free, casein-free diet. I feel better after stressful day with it.
The diet is only a piece of the puzzle. Cleansing the body of metals and bugs is the main work in my opinion.
Personally my major problems are from mercury and then everything comes from it. Chelation helps me but only chelation is not the 100% cure.
The healing process is complicated work with numerous factors.
Don't lose courage. Pray to GOD and you'll be OK. I was desperate as you are.
Removing metals will relieve anxiety, bad feelings, pressure etc... You can't be ok if you are full with mercury and unavailabale copper... Metals are really bad and I know that. For lyme, ask Newport.
