What's wrong with more than 1gr calcium and sugar + caffeine long term? Same question for some fatty cheese ?I wouldn't go the calcium route, it will probably make it worse. Calcium is OK from foods up to 1gr.
"Peat's diet" may probably be one of the most destructive diets long term. Sugar, calcium, caffeine and long chain SFA in excess... along with avoiding intense exercising. Nice recipe for disaster (I mean for an already normal healthy individual).
