Hi, Dr. Sears,
Q: Does the Zone Diet have any impact on the stabilization of anti-diuretic hormone levels? I have something that appears similar to diabetes insipidus, but it only happens occasionally, so no one can figure out what it is. Some of the triggers appear to be eating sugar or simple carbs (doesn't happen every time), or going most of the day without eating carbs, so I'm wondering if stabilizing blood sugar with the Zone has any impact on ADH.
A: I believe that maintaining a constant level of insulin may ideally stabilize the levels of ADH, especially since the extremes of carb intake seem to be associated with its swings.
