Have you had an allergy panel done? With clean food you end up having more of single substances. Allergies could explain a lot. My daughter recently was feeling terrible all the time. She actually ended up in the ER from eating virtually anything. Her allergy results came back after a couple of weeks showing very high allergies to nearly all meat, plus as expected dairy and eggs.
Starting Primal June 2012 at 148.5lbs, goal weight in November 2012.
Lowest weight 93lbs - too thin. Now up to around 101lbs and holding.
Primal, minus eggs, dairy and a myriad of other allergens.
